●

Do not use your watch for scuba diving or

other types of diving that requires air tanks.

●

Watches that do not have WATER RESIST

or WATER RESISTANT marked on the

back cover are not protected against the

effects of sweat. Avoid using such a watch

under conditions where it will be exposed to

large amounts of sweat or moisture, or to

direct splashing with water.

●

Even if a watch is water resistant, note the

usage precautions described below. Such

types of use reduce water resistance

performance and can cause fogging of the

glass.

ー　

Do not operate the crown or buttons while

your watch is submersed in water or wet.

ー　

Avoid wearing your watch while in the

bath.

ー　

Do not wear your watch while in a heated

swimming pool, sauna, or any other high

temperature/high humidity environment.

ー　

Do not wear your watch while washing

your hands or face, while doing

housework, or while performing any other

task that involves soaps or detergents.

●

After submersion in seawater, use plain

water to rinse all salt and dirt from your

watch.

●

To maintain water resistance, have the

gaskets of your watch replaced periodically

(about once every two or three years).

●

A trained technician will inspect your watch

for proper water resistance whenever you

have its battery replaced. Battery

replacement requires the use of special

tools. Always request battery replacement

from your original retailer or from an

authorized CASIO service center.

●

Some water-resistant watches come with

fashionable leather bands. Avoid

swimming, washing, or any other activity

that causes direct exposure of a leather

band to water.

●

The inside surface of the watch glass may

fog when the watch is exposed to a sudden

drop in temperature. No problem is

indicated if the fogging clears up relatively

quickly. Sudden and extreme temperature

changes (such as coming into an air

conditioned room in the summer and

standing close to an air conditioner outlet,

or leaving a heated room in the winter and

allowing your watch to come into contact

with snow) can cause it to take longer for

glass fogging to clear up. If glass fogging

does not clear up or if you notice moisture

inside of the glass, immediately stop using

your watch and take it to your original

retailer or to an authorized CASIO service

center.

●

Your water-resistant watch has been tested

in accordance with International

Organization for Standardization

regulations.

●

Band

●

Tightening the band too tightly can cause

you to sweat and make it difficult for air to

pass under the band, which can lead to skin

irritation. Do not fasten the band too tightly.

There should be enough room between the

band and your wrist so you can insert your

finger.

●

Deterioration, rust, and other conditions can

cause the band to break or come off of your

watch, which in turn can cause band pins to

fly out of position or to fall out. This creates

the risk of your watch falling from your wrist

and becoming lost, and also creates the risk

of personal injury. Always take good care of

your band and keep it clean.

●

Immediately stop using a band if you even

notice any of the following: loss of band

flexibility, band cracks, band discoloration,

band looseness, band connecting pin flying

or falling out, or any other abnormality. Take

your watch to your original retailer or to a

CASIO service center for inspection and

repair (for which you will be charged) or to

have the band replaced (for which you will

be charged).

Watch Operation Guide 3554

●

Temperature

●

Never leave your watch on the dashboard

of a car, near a heater, or in any other

location that is subject to very high

temperatures. Do not leave your watch

where it will be exposed to very low

temperatures. Temperature extremes can

cause your watch to lose or gain time, to

stop, or otherwise malfunction.

●

Leaving your watch in an area hotter than

+60 °C (140 °F) for long periods can lead to

problems with its LCD. The LCD may

become difficult to read at temperatures

lower than 0 °C (32 °F) and greater than

+40 °C (104 °F).

●

Impact

●

Your watch is designed to withstand impact

incurred during normal daily use and during

light activity such as playing catch, tennis,

etc. Dropping your watch or otherwise

subjecting it to strong impact, however, can

lead to malfunction. Note that watches with

shock-resistant designs (G‑SHOCK,

BABY‑G, G‑MS) can be worn while

operating a chain saw or engaging in other

activities that generate strong vibration, or

while engaging in strenuous sports

activities (motocross, etc.)

●

Magnetism

●

Though operation of your watch normally is

not affected by magnetism, its accuracy

may be affected if the watch itself becomes

magnetized. Also, very strong magnetism

(from medical equipment, etc.) should be

avoided because it can cause malfunction

of your watch and damage to electronic

components.

●

Electrostatic Charge

●

Exposure to very strong electrostatic

charge can cause your watch to display the

wrong time. Very strong electrostatic

charge even can damage electronic

components.

●

Electrostatic charge may cause temporary

blotching in blank areas of the LCD.

●

Chemicals

●

Do not allow your watch to come into

contact with thinner, gasoline, solvents,

oils, or fats, or with any cleaners, adhesives,

paints, medicines, or cosmetics that contain

such ingredients. Doing so can cause

discoloration of or damage to the resin

case, resin band, leather, and other parts.

●

Storage

●

If you do not plan to use your watch for a

long time, thoroughly wipe it free of all dirt,

sweat, and moisture, and store it in a cool,

dry place.

●

Resin Components

●

Allowing your watch to remain in contact

with other items or storing it together with

other items for long periods while it is wet

can cause color on resin components to

transfer to the other items, or the color of the

other items to transfer to the resin

components of your watch. Be sure to dry

off your watch thoroughly before storing it

and make sure it is not in contact with other

items.

●

Leaving your watch where it is exposed to

direct sunlight (ultraviolet rays) for long

periods or failure to clean dirt from your

watch for long periods can cause it to

become discolored.

●

Friction caused by certain conditions

(strong external force, sustained rubbing,

impact, etc.) can cause discoloration of

painted components.

●

If there are printed figures on the band,

strong rubbing of the printed area can cause

discoloration.

●

Leaving your watch wet for long periods can

cause fluorescent color to fade. Wipe the

watch dry as soon as possible after it

becomes wet.

●

Semi-transparent resin parts can become

discolored due to sweat and dirt, and if

exposed to high temperatures and humidity

for long periods.

●

Daily use and long-term storage of your

watch can lead to deterioration, breaking, or

bending of resin components. The extent of

such damage depends on usage conditions

and storage conditions.

●

Leather Band

●

Allowing your watch to remain in contact

with other items or storing it together with

other items for long periods while it is wet

can cause the color of the leather band to

transfer to the other items or the color of the

other items to transfer to the leather band.

Be sure to dry off your watch thoroughly with

a soft cloth before storing it and make sure

it is not in contact with other items.

●

Leaving a leather band where it is exposed

to direct sunlight (ultraviolet rays) for long

periods or failure to clean dirt from a leather

band for long periods can cause it to

become discolored.

CAUTION:

Exposing a leather band to rubbing or dirt

can cause color transfer and discoloration.

●

Metal Components

●

Failure to clean dirt from metal components

can lead to formation of rust, even if

components are stainless steel or plated. If

metal components exposed to sweat or

water, wipe thoroughly with a soft,

absorbent cloth and then place the watch in

a well-ventilated location to dry.

●

Use a soft toothbrush or similar tool to scrub

the metal with a weak solution of water and

a mild neutral detergent, or with soapy

water. Next, rinse with water to remove all

remaining detergent and then wipe dry with

a soft absorbent cloth. When washing metal

components, wrap the watch case with

kitchen plastic wrap so it does not come into

contact with the detergent or soap.

●

Bacteria and Odor Resistant Band

●

The bacteria and odor resistant band

protects against odor generated by the

formation of bacteria from sweat, which

ensures comfort and hygiene. In order to

ensure maximum bacteria and odor

resistance, keep the band clean. Use an

absorbent soft cloth to thoroughly wipe the

band clean of dirt, sweat, and moisture. A

bacteria and odor resistant band

suppresses the formation of organisms and

bacteria. It does not protect against rash

due to allergic reaction, etc.

Watch Operation Guide 3554

●

Liquid Crystal Display

●

Display figures may be difficult to read when

viewed from an angle.

●

Watch with Data Memory

●

Allowing the battery to go dead, replacing

the battery, or having your watch repaired

can cause all data in watch memory to be

lost. Note that CASIO Computer Co., Ltd.

assumes no responsibility for any damages

or losses caused by data lost due to

malfunction or repair of your watch,

replacement of the battery, etc. Be sure to

keep separate written copies of all

important data.

●

Watch Sensors

●

A watch sensor is a precision instrument.

Never try to take it apart. Never try to insert

any objects into the openings of a sensor,

and take care to ensure that dirt, dust, or

other foreign matter does not get into it.

After using your watch where it has been

immersed in saltwater, rinse it thoroughly

with fresh water.

●

Heart Rate Monitor Functions

●

The back cover of the watch has a built-in

sensor that detects your pulse. This is used

to calculate and display an approximate

heart rate value. The factors below can

cause error in the displayed heart rate

value.

ー　

How the watch is affixed to the wrist

ー　

Individual wrist characteristics and

conditions

ー　

Training type and intensity

ー　

Sweat, dirt, and/or other foreign matter

near the sensor

All of this means that heart rate values

displayed by the watch are approximate,

and no guarantees are made concerning

their accuracy.

●

The heart rate monitor function of this watch

is intended for recreational purposes, and

should not be used in any way for medical

purposes.

●

Chargeable Battery Handling (Please

recycle!)

The built-in lithium-ion battery includes

valuable resources. When you are ready to

discard your watch, follow proper procedures

in order to recycle resources. For information

about the proper procedure to follow when

discarding the watch, contact an authorized

CASIO service center or your original retailer.

Important!

●

Do not try to replace batteries by

yourself. Request battery replacement

from an authorized CASIO service

center or your original retailer.

●

Personal Information Protection

Precautions

To protect your personal information, be sure

to perform the operation under “Resetting

Watch Settings” before transferring

ownership of this watch to another party or

before disposing of it.

Note that CASIO Computer Co., Ltd.

assumes no responsibility for any

damage or loss suffered by you or any

third party arising through the use of your

watch or its malfunction.

User Maintenance

●

Caring for Your Watch

Remember that you wear your watch next to

your skin, just like a piece of clothing. To

ensure your watch performs at the level for

which it is designed, keep it clean by

frequently wiping with a soft cloth to keep your

watch and band free of dirt, sweat, water and

other foreign matter.

●

Whenever your watch is exposed to sea

water or mud, rinse it off with clean fresh

water.

●

For a metal band or a resin band with metal

parts, use a soft toothbrush or similar tool to

scrub the band with a weak solution of water

and a mild neutral detergent, or with soapy

water. Next, rinse with water to remove all

remaining detergent and then wipe dry with

a soft absorbent cloth. When washing the

band, wrap the watch case with kitchen

plastic wrap so it does not come into contact

with the detergent or soap.

●

For a resin band, wash with water and then

wipe dry with a soft cloth. Note that

sometimes a smudge like pattern may

appear on the surface of a resin band. This

will not have any effect on your skin or

clothing. Wipe with a cloth to remove the

smudge pattern.

●

Clean water and sweat from a leather band

by wiping with a soft cloth.

●

Not operating a watch crown, buttons, or

rotary bezel could lead to later problems

with their operation. Periodically rotate the

crown and rotary bezel, and press buttons

to maintain proper operation.

Watch Operation Guide 3554

●

Dangers of Poor Watch Care

Rust

●

Though the metal steel used for your watch

is highly rust-resistant, rust can form if your

watch is not cleaned after it becomes dirty.

ー　

Dirt on your watch can make it impossible

for oxygen to come into contact with the

metal, which can lead to breakdown of

the oxidization layer on the metal surface

and the formation of rust.

●

Rust can cause sharp areas on metal

components and can cause band pins to fly

out of position or to fall out. If you ever notice

any abnormality immediately stop using

your watch and take it to your original

retailer or to an authorized CASIO service

center.

●

Even if the surface of the metal appears

clean, sweat and rust in crevasses can soil

the sleeves of clothing, cause skin irritation,

and even interfere with watch performance.

Premature Wear

●

Leaving sweat or water on a resin band or

bezel, or storing your watch an area subject

to high moisture can lead to premature

wear, cuts, and breaks.

Skin Irritation

●

Individuals with sensitive skin or in poor

physical condition may experience skin

irritation when wearing a watch. Such

individuals should keep their leather band

or resin band particularly clean. Should you

ever experience a rash or other skin

irritation, immediately remove your watch

and contact a skin care professional.

Battery

●

The special rechargeable battery used by

your watch is not intended to be removed or

replaced by you. Use of a rechargeable

battery other than the special one specified

for your watch can damage your watch.

●

The rechargeable (secondary) battery can

be charged by using the charging cable to

connect the watch to a device equipped

with a USB terminal, so it does not require

regular replacement as the primary battery

requires. Note, however, that long use or

operating conditions can cause the

capacity or charging efficiency of the

rechargeable battery to deteriorate. If you

feel that the amount of operation provided

by charging is too short, contact your

original retailer or CASIO service center.

●

Regular, once-a-month charging is

recommended to extend the service life of

the watch’s battery.

date and time of the measurement.

You can also measure the altitude

differential between two points.

●

Barometric Pressure and Temperature

Measurement

You can display the current barometric

pressure tendency, which helps you be on

the alert for noteworthy pressure changes.

The watch can be used to take current air

temperature readings.

●

Tide Function

You can view tide information (Tide Graph)

for the port you specified.

Important!

●

This watch is not a special-purpose

measuring instrument. Measurement

function readings are intended for

general reference only.

●

When using this watch for serious

trekking, mountain climbing, or other

activities, always take along another

compass to confirm readings. If the

readings produced by this watch are

different from those of the other

compass, perform figure 8-calibration

of the watch’s compass to ensure

better accuracy.

ー　

Compass readings and calibration

will not be possible if the watch is in

the vicinity of a permanent magnet

(magnetic accessory, etc.), metal

objects, high-voltage wires, aerial

wires, or electrical household

appliances (TV, computer,

cellphone, etc.)

Compass Reading

●

The watch’s altimeter function

calculates and displays relative

altitude based on barometric pressure

readings produced by its pressure

sensor. Because of this, altitude

values displayed by the watch may be

different from your actual elevation

and/or sea level elevation indicated for

the area where you are located.

Regular calibration in accordance with

the local altitude (elevation)

indications is recommended.

Altitude Measurement

●

The illustrations included in this

operation guide have been created to

facilitate explanation. An illustration

may differ somewhat from the item it

represents.

●

You can obtain more accurate display

values by creating a profile before

measuring your heart rate or activity

data.

Creating Your Profile

●

Depending on the version of your

watch’s software, its operations and

display contents may differ from those

described in this Operation Guide.

Charging the Watch

The charging cable can be used to charge the

watch. The watch can also be charged by

sunlight or other light, in addition to electrical

power.

Charging with the Charger Cable

Charging with the charger cable is faster than

solar charging.

Important!

●

Use only the supplied charger cable for

charging.

●

A device with a USB port (Type-A) can

also be used for charging.

●

Note that no guarantees are made

concerning the suitability of all types of

USB ports for charging. If charging is

not possible for some reason,

disconnection from the USB port is

recommended.

●

Place the charger on a desk or other

stable surface, making sure there is

plenty of open space around it.

Charging with the charger and watch in

a bag or some other enclosed space

can cause overheating of the watch.

●

Should water or any other liquid get

onto the watch or charger cable during

charging, immediately unplug the

charger cable from the power source.

●

Perform charging in an environment

where ambient temperature is

between 5 °C and 35 °C (41 °F and

95 °F).

●

Avoid pinching your hands or fingers in

the gap of the clip of the charging

cable.

●

Charging the Watch

USB

1. Turn on your computer or other device

disappears. Charging stops at this time.

●

Charging from a Non-computer

Device’s USB Port

You can charge using power from a USB port

(Type-A) that meets USB standards.

●

Voltage: 5 V

●

Current: 0.5 A min.

●

Precautions When Charging

●

A charging operation will not start while the

battery level indicator shows . To

prolong the life of the watch’s rechargeable

battery, charge only while the battery level

indicator shows or lower.

●

Do not attempt charging at high ambient

temperatures of 35 °C (95 °F) or greater.

The watch becomes hot during charging,

which can cause charging to stop

automatically. High ambient temperature

may result in a less than full charge.

●

Operation on a custom computer or a

computer that has been modified from its

original configuration is not guaranteed.

●

The watch may become warm during

charging. This is normal and does not

indicate malfunction.

Note

●

Starting from a blank display, it takes

about 3.2 hours to achieve a full

charge.

●

Charging time depends on ambient

temperature and other factors.

Watch Operation Guide 3554

Solar Charging

Power generated by the solar panel powers

watch operations and also is used to charge a

rechargeable (secondary) battery. The solar

panel is integrated into the LCD of the watch,

and power for charging is generated

whenever the face is exposed to light.

●

Charging the Watch

When you are not wearing the watch, put it in

a location where it is exposed to bright light.

While you are wearing the watch, make sure

that its LCD (solar panel) is not blocked from

light by the sleeve of your clothing. Power

generation efficiency is reduced even when

the LCD is blocked only partially.

NOYES

Important!

●

Depending on light intensity and local

conditions, the watch may become hot

to the touch when exposed to light for

charging. Take care to avoid burn

injury after charging. Also, avoid

charging the watch under high-

temperature conditions like the ones

described below.

ー　

On the dashboard of a vehicle

parked in the sun

OPEN WATER SWIMMING uses GPS

to measure the distance you swim.

However, since GPS signals are

affected by the external factors

described below, it may not be

possible to record distances you swim

accurately.

ー　

Water surface reflects GPS signals,

which affects measurement

accuracy.

ー　

GPS signals are difficult to receive

underwater, so GPS signals are lost

whenever the watch is submerged.

To improve distance and route

measurement accuracy using GPS,

refer to the points below.

ー　

After successfully receiving GPS

signals, wait a few minutes before

starting activity measurement. This

will allow the GPS sensor to warm up

and provide time for the watch to

download the necessary GPS

information.

ー　

When swimming, make sure that the

wrist where you are wearing the

watch is above the surface of the

water. Depending on your

swimming style, distance and

trajectory may not be recorded

accurately.

Starting Heart-rate Training

With heart-rate training, you measure your

heart rate and then use the resulting value as

a benchmark for training. You can monitor

your heart rate levels and keep your exercise

intensity in line with your training goals, which

contributes to more efficient training,

improved cardiopulmonary function, and

better health.

* Heart Rate Zone (HR zones)

●

To specify a target heart rate zone

Specify a target heart rate zone that matches

your training objectives.

The range from 50% to 100% of your

maximum heart rate is divided into five heart

rate zones. You can easily control the intensity

of your training by keeping your heart rate

within a particular zone. Each heart rate zone

has a main effect, and understanding these

effects can enhance the effectiveness of your

training.

●

Zone 1 (50 to 60% of maximum heart rate):

Very light training

Zone 1 training improves overall health and

helps you recover from more strenuous

training.

You can continue training in this zone for

long periods.

●

Zone 2 (60 to 70% of maximum heart rate):

Light training

Zone 2 training increases general stamina.

It uses fat as an energy source, improving

the body’s ability to burn fat.

You can continue training comfortably in

this zone for long periods.

●

Zone 3 (70 to 80% of maximum heart rate):

Moderate training

Zone 3 training improves aerobic fitness. It

causes lactic acid to begin to accumulate in

the bloodstream, but the body can reuse the

lactic acid for energy, so it does not affect

performance.

Since Zone 3 training requires deeper

breathing, you will feel the need for a

moderate amount of effort.

●

Zone 4 (80 to 90% of maximum heart rate):

Hard training

Zone 4 training improves speed endurance

and enhances the ability of the body to use

protein (sugar) for energy. In addition, Zone

4 training allows you to tolerate high levels

of lactic acid in the blood.

Zone 4 training results in muscle fatigue and

rough breathing.

●

Zone 5 (90 to 100% of maximum heart rate):

Very hard training

Zone 5 training improves maximum

performance. Large amounts of lactic acid

are accumulated, so long-term training is

not possible.

Zone 5 training results in labored breathing

and muscle fatigue.

Digital Compass Reading

Precautions

Location During Use

Taking readings near sources of strong

magnetism can cause reading error. Keep the

watch away from the following types of items.

Permanent magnets (magnetic accessories,

etc.), metal objects, high-voltage wires, aerial

wires, electrical household appliances (TVs,

computers, cellphones, etc.)

●

Note that correct direction readings are not

possible indoors, especially inside of

reinforced concrete structures.

●

Accurate direction readings are not

possible on electric trains, on boats, on

aircraft, etc.

Storage Location

Exposure of the watch to magnetism can

affect the accuracy of digital compass

readings. Keep the watch away from the types

of items below.

Permanent magnets (magnetic accessories,

etc.), metal objects, electrical household

appliances (TVs, computers, cellphones, etc.)

Altitude

Measurement

The watch takes altitude readings and

displays results based on air pressure

measurements taken by a built-in pressure

sensor.

Important!

●

The altitude readings displayed by the

watch are relative values that are

calculated based on barometric

pressure measured by the watch’s

pressure sensor. This means that

barometric pressure changes due to

weather can cause altitude readings

taken at the same location to be

different. Also note that the value

displayed by the watch may be

Altitude Reading

Precautions

Effects of Temperature

When taking altitude readings, take the steps

below to keep the watch at as stable a

temperature as possible. Changes in

temperature can affect altitude readings.

●

Take readings with the watch on your wrist.

●

Take readings in an area where

temperature is stable.

Altitude Readings

●

Do not use this watch while skydiving, hang

gliding, paragliding, gyrocopter flying, glider

flying, or engaged in other activities where

altitude changes suddenly.

●

Altitude readings produced by this watch

are not intended for special-purpose or

industrial level use.

●

In an aircraft, the watch measures the in-

cabin pressurized air pressure, so readings

will not match altitudes announced by the

crew.

Altitude Readings (Relative Altitude)

This watch uses International Standard

Atmosphere (ISA) relative altitude data

defined by the International Civil Aviation

Organization (ICAO). Barometric pressure

generally becomes lower as altitude

increases.

Correct measurement may not be possible

under the conditions below.

●

During unstable atmospheric conditions

●

During sudden temperature changes

●

After the watch has been subjected to

strong impact

Watch Operation Guide 3554

Measured Altitude Value Adjustment

Using GPS Signal Data

If you performed a GPS signal receive

operation before starting measurement of an

activity that uses GPS signals for

measurement, the measured altitude value

will be automatically corrected when the

watch receives correction information. Note,

however, that this also may result in some

difference between the measured value and

the actual altitude.

Also note that the measured altitude value

adjustment operation using GPS signal data

may take a few minutes. The adjustment

operation may take even longer, depending

on your current environment. Regular manual

adjustment of the measured altitude value

using locally available information is

recommended. The watch will not use GPS

signal data to adjust measured altitude values

for one hour after you adjust the measured

altitude value manually.

Barometric Pressure

and Temperature

Measurement

You can use the watch to take barometric

pressure and temperature readings for your

current location.

Thermometer measurement: -10.0 °C

to 60.0 °C (14.0 °F to 140.0 °F)

●

Large changes in barometric pressure

and/or temperature can cause past

data readings to be plotted outside of

the visible area of the graph. Though

plots are not visible, the data is still

maintained in watch memory.

Barometric Pressure Change

Indications

Whenever the watch detects a significant

change in air pressure readings (due to

sudden altitude change, or to the passage of

a low pressure or high pressure area), it will

perform a sound and/or vibration operation

and display a flashing arrow to let you know.

The arrow that appears shows the direction of

the pressure change. These alerts are called

“Barometric Pressure Change Indications”.

●

The watch will notify you by a 10-second

sound/vibration operation when there is a

sudden drop in atmospheric pressure.

●

A four-second sound/vibration operation

will notify you when there is a sudden rise in

atmospheric pressure, or the passage of

high or low pressure.

This

indication:

Means this:

Sudden drop in pressure

Sudden rise in pressure

Sustained rise in pressure,

shifting to a fall

Sustained fall in pressure, shifting

to a rise

Important!

●

To ensure correct barometric pressure

change indication operation, enable it

in a location where the altitude is

constant (such as a lodge, camp area,

or on the ocean).

●

A change in altitude causes a change

in air pressure. Because of this, correct

readings are impossible. Do not take

readings while ascending or

descending a mountain, etc.

information is included.

●

You may experience location

information acquisition problems in the

vicinity of a city borderline.

The watch’s time and day is not be

indicated correctly if the time zone

setting is not right for your location. If

this happens, move to a location near

the center of the city you want to set as

your Home City and acquire location

information again.

Leap Second Reception

GPS signal reception each year on June 1 or

later and on December 1 or later also receives

leap second information.

Note

●

It can take as long as 15 minutes to

complete the leap second information

receive operation.

●

The leap second information receive

operation is repeated until information

receipt is complete.

●

Once the leap second information

receive operation is complete, the

watch will not make any attempt to

receive it again until the following June

1 or December 1.

●

When connecting with a phone to

adjust the watch date and time

settings, leap seconds will also be

received along with the time

information. If this happens, leap

seconds may not be received when

receiving a GPS signal.

●

The first GPS signal receive operation

after the watch’s current time and/or

date setting has been changed

manually will include receipt of leap

second information.

Watch Operation Guide 3554

Signal Reception Precautions

●

When the watch is unable to adjust its time

in accordance with a GPS signal for some

reason, average timekeeping accuracy is

within ±15 seconds per month.

●

Note that an internal decoding process the

watch performs after it receives a GPS

signal may cause the time setting to be

slightly off (by less than one second).

●

GPS signal reception is not possible under

the conditions described below.

ー　

While

or lower is displayed for the

battery level

ー　

While the watch is connected with a

phone and data communication is in

progress

ー　

While the watch’s Airplane Mode is

enabled

ー　

While sleep measurement is in progress

●

If the receive operation is successful, the

time and day settings will be adjusted

automatically in accordance with the Home

City (time zone) and summer time settings.

Summer time will not be applied correctly in

the cases described below.

ー　

When the summer time start date and

time, end date and time, or other rules are

changed by authorities

ー　

When location information is received,

but it is not location information for your

actual location (For example, when you

are near a borderline of a city and the

acquired location information is for a

neighboring city, etc.)

Using GPS Outside Your Country

Some countries or geographic areas put legal

restrictions on the use of GPS, on the

collection and logging of location information,

etc. Your watch has built-in GPS functionality,

so before embarking on international travel to

a country or area outside of the country where

you purchased your watch, you should check

with the embassy of the countries you plan to

visit, your travel agency, or some other reliable

source of information to find out if there are any

prohibitions or restrictions on bringing in

devices with GPS functionality, or on the

logging of location information, etc.

Using Watch Operations to

Adjust the Time Setting

When your watch cannot communicate with

your phone or receive GPS signals for some

reason, you can adjust date and time settings

on the watch manually.

Watch Operation Guide 3554

Viewing the Face in the Dark

The watch has a light that illuminates the face

for viewing in the dark.

●

The light turns on each time you perform a

button operation.

●

Illumination is turned on when the sounds or

vibrations start by Auto Lap, notification or

alarm etc. Illumination that is turned on by a

notification operation cannot be turned off.

●

To illuminate the face manually

Press (B) to turn on illumination.

●

Illumination will turn off automatically if an

alarm starts to sound.

●

Using Auto Light

If Auto Light is enabled, face illumination will

turn on automatically whenever the watch is

positioned at an angle of 40 degrees or more.

degrees

or more

For information about enabling Auto Light, see

the information below.

Configuring the Auto Light Setting

Important!

●

Auto Light may not operate properly

when the watch is at a horizontal angle

of 15 degrees or greater from

horizontal as shown in the illustration

below.

●

Electro-static charge or magnetism

can interfere with proper auto light

operation. If this happens, try lowering

your arm and then angle it towards

your face again.

●

When moving the watch you may note

a slight rattling sound. This is due to

operation of the auto light switch,

which determines the current

orientation of the watch. It does not

indicate malfunction.

Note

●

If Auto Light is enabled, face

illumination may be delayed if you

angle the watch towards your face

while a compass, altitude, barometric

pressure, or temperature reading

operation is being performed.

Fastening the Watch to Your

Wrist

Correctly wearing the watch on your wrist is

essential to obtain accurate heart rate,

breathing exercise, and sleep measurements.

Especially when using the watch while running

or performing other strenuous exercises,

make the adjustments described below to

ensure that the watch does not shake or shift.

1. With the watch fastened loosely on your

wrist, place at least one finger to the right

of the watch* (Figure).

* If you wear the watch on your right wrist,

place your finger(s) to the left of the (C)

button (left side of the watch).

Figure

2. Position the watch so there is at least one

finger width between it and the bone that

protrudes from the side of your wrist

(Figure).

●

The location and shape of this bone

(circled in the illustration) differ from

person to person.

3. After you determine the best wrist position

for the watch, tighten the band securely

enough to keep the watch from sliding on

your wrist.

Important!

●

A band that is snugly tightened for

heart rate or other measurements can

make it difficult for air to pass under the

band and cause you to sweat, which

can lead to skin irritation. After

measuring your heart rate, loosen the

band enough so you can insert a finger

between it and your wrist.

●

Wearing the watch for long periods,

sweat, or certain usage environments

create the risk of skin rash. To prevent

skin problems, regularly remove your

watch from your wrist to give your skin

some time to rest.

●

The watch is not fastened correctly to

your wrist if you can see green light

coming out from behind the watch.

●

Keep your arms still during breathing

exercise measurement.

●

For details about how to wear the

watch during blood oxygen level

measurements, see the information

below.

Troubleshooting

Charging with the Charger

Cable

The watch won’t charge with the

charger cable.

Is the end of the charger cable with the

special watch connector securely aligned

with the watch charger terminal?

Charging may fail if there is space

between the terminals.

Precautions When Charging

Did you leave the watch attached to the

charger cable after charging was

complete?

Charging stops automatically after the

Heart Rate Measurement

[ERROR] is displayed during

measurement.

There may be a problem with the sensor. Try

taking another measurement. If [ERROR]

keeps appearing after multiple measurement

attempts, contact a CASIO service center or

your original retailer.

Altitude Measurement

Readings produce different results at

the same location.

Watch readings are different from

altitude information available from

other sources.

Correct altitude readings are not

possible.

Relative altitude is calculated based on

changes in barometric pressure measured by

the watch’s pressure sensor. This means that

barometric pressure changes can cause

readings taken at the same location to be

different. Also note that the value displayed by

the watch may be different from the actual

elevation and/or sea level elevation indicated

for the area where you are located. When

using the watch’s altimeter while mountain

climbing, it is recommended that you regularly

calibrate its readings in accordance with local

altitude (elevation) indications.

Calibrating Altitude Readings

[- - - - -] appears on the display

following altitude differential

measurement.

[- - - - -] appears on the display when the

altitude differential is outside the allowable

measuring range (±3,000 m (±9,840 feet)). If

[ERROR] is displayed, there may be a

problem with the sensor.

Setting a Reference Altitude and Taking

Altitude Differential Readings

[ERROR] is displayed during

measurement.

There may be a problem with the sensor. Try

taking another measurement. If [ERROR]

keeps appearing after multiple measurement

attempts, contact a CASIO service center or

your original retailer.

Digital Compass

The symbol [ ] is shown on the

display.

Accessing the compass function causes

[ ] to appear on the display. This icon will

disappear when you perform a bearing

measurement operation.

Taking a Compass Reading

If [ ] appears on the display during

bearing or activity measurements, it means

abnormal magnetism was detected. Move

away from any potential source of strong

magnetism and try taking a reading again.

If [ ] appears again, it could mean that the

watch body has become magnetized. Move

away from any potential source of strong

magnetism, perform direction calibration, and

then try taking a reading again.

Calibrating the Compass

Digital Compass Reading Precautions

[ERROR] is displayed during

measurement.

There is a problem with the sensor or there

may be a source of strong magnetic force

nearby. Move away from any potential source

of strong magnetism and try taking a reading

again. If [ERROR] keeps appearing after

multiple measurement attempts, contact a

CASIO service center or your original retailer.

Digital Compass Reading Precautions

[ERROR] appears on the display

following direction calibration.

If [- - -] is followed by [ERROR] on the display,

it could mean there is something wrong with

the sensor.

●

If [ERROR] disappears after about one

second, try calibrating again.

●

If [ERROR] keeps appearing after multiple

attempts, contact a CASIO service center or

your original retailer.

Direction information indicated by the

watch is different from that indicated

by a backup compass.

Move away from any potential source of

strong magnetism, perform direction

calibration, and then try taking a reading

again.

Calibrating the Compass

Digital Compass Reading Precautions

Readings at the same location

produce different results.

Pedometer

Displayed step count is not correct.

While the watch is on your wrist, it may detect

non-step movements and count them as

steps.

Counting Steps

Also, step count problems can also be caused

by how the watch is being worn and abnormal

arm movement while walking.

Causes of Incorrect Step Count

The step count does not increase.

To prevent erroneous counting, the count

display does not increase immediately after

you start walking.

[ERROR] appears when using the

pedometer.

[ERROR] (error) is displayed when sensor

operation is disabled because of sensor or

internal circuitry malfunction.

If the indicator remains on the display for more

than three minutes or if it frequently appears,

it could indicate a faulty sensor.

Contact a CASIO service center or your

original retailer.

Tide Function

There are errors in the tide

information.

Since the high tide and low tide times and tide

levels of the Tide Graph are calculated based

on past data, the calculated data may be

different from actual tide information.

Also note that the degree of the error can be

affected by terrain, weather, and other

conditions. Use the tide information of this

watch for reference only.

Be sure to check accurate tide forecast

information issued by various organizations,

and do not use the tide information of this

watch to determine tide levels used for

navigation or any other purpose where there

is the risk of danger.

Alarm

There is no sound and/or vibration

operation performed for alarms.

Is the watch’s battery charged?

Charge the watch until the battery is

sufficiently recharged.
