●

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 3567

●

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 a digital watch normally is not

affected by magnetism, very strong

magnetism (from medical equipment, etc.)

should be avoided because it can cause

malfunction 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 can cause the display

to go blank momentarily or cause a rainbow

effect on the display.

●

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 3567

●

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.

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.

●

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.

Watch Operation Guide 3567

Battery Replacement

●

Leave battery replacement up to your

original retailer or authorized CASIO

service center.

●

Have the battery replaced only with the type

specified in the “Specifications”. Use of a

different battery type can cause

malfunction.

●

When replacing the battery, also request a

check for proper water resistance.

●

Ornamental resin components may

become worn, cracked, or bent over time

when subjected to normal daily use. Note

that if cracking or any other abnormality

indicating possible damage is noticed in a

watch submitted for battery replacement,

your watch will be returned with an

explanation of the abnormality, without the

requested servicing being performed.

●

normal daily activities, etc.

Counting Steps

If you are wearing the watch correctly, the

watch will count your steps as you walk or

engage in your normal daily activities.

Important!

●

Since this watch is a wrist-worn device,

it may detect non-step movements and

count them as steps. Also, abnormal

arm movements while walking may

cause a miss count of steps.

●

Getting Ready

To enable the most accurate step count, wear

the watch with the face on the outside of your

wrist and tighten the band securely. A loose

band may make it impossible to obtain correct

measurement.

The watch does not connect with a

phone and correct its time when I

press (D).

Time setting syncing will not be performed if

you press (D) while a stopwatch elapsed time

measurement operation or a timer countdown

operation is in progress. Stop the current

stopwatch or timer operation, and then press

(D) again.

Time is not displayed correctly.

If your phone is unable to receive a signal

because you are outside its service range or

for some other reason, the watch may not be

able to display the correct time. If this

happens, connect the phone to its network

and then correct the time setting.

Step Count

Displayed step count is not correct.

While the watch is on your wrist, it may detect

non-step movements and count them as

steps.

Step Count

Also, step count problems can also be caused

by how the watch is being worn and abnormal

arm movement while walking.

Counting Steps

The step count does not increase.

To avoid miscounting non-walking

movements, the step count or distance value

is not displayed for about 18 seconds after you

start to walk.

It appears only after you have continued

walking for about 18 seconds, with the number

of steps you took during the first 18 seconds

included in the total.

[ERR] appears when counting steps.

[ERR] (error) indicates that 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.

[R] may appear on the display when the

watch’s battery power is low, or if you use the

light or other functions a number of times

during a short period, which momentarily

causes the battery level to go low. If this

happens, all watch functions, except for

timekeeping, become disabled.

If [R] remains on the display or if it keeps

appearing, it may indicate that the battery

needs to be replaced.

Request battery replacement from a CASIO

service center or your original retailer.
