I can’t get correct altitude readings.
Relative altitude is calculated based on changes in barometric pressure measurement by the watch’s
pressure sensor. This means that barometric pressure changes can cause readings taken at different
times 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, you need to be sure to perform regular
calibration in accordance with the local altitude (elevation) indications.
For more information, see “To specify a reference altitude value” (page E-70).
■
Following a relative altitude reading, the watch’s second hand points to 9 o’clock.
• The reading value is outside of the allowable measurement range. See page E-68.
• This could indicate sensor error. If
ERR
(error) is on the digital display, refer to “Barometric Pressure,
Bearing, Altitude, Temperature, and Depth Readings” (page E-120) for more information.
Depth Meter Mode
■
The watch will not enter the Depth Meter Mode.
LOW
or
HML
fl
ashing on the screen indicates that the watch is in the charge recovery state. The watch
will not enter the Depth Meter Mode while it is in the charge recovery state.
■
ERR appears when I try to enter the Depth Meter Mode.
This indicates that the reference pressure for setting the 0-meter depth is outside of the sensor’s allowable
measuring range. If the high-altitude limit pressure is 530 hPa or lower, a
ERR
will occur. If the water
depth limit pressure is 9,500 hPa or greater, a
ERR
will occur.

■
The 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 fi gure 8 calibration or 3-point
calibration, and then try taking a reading again. For more information, refer to “To perform fi
gure 8
calibration” (page E-58), “To perform 3-point calibration” (page E-60), and “Location” (page E-65).
■
Direction readings produce different results at the same location.
• Move away from any potential source of strong magnetism and try taking a reading again. See
“Location” (page E-65).
■
I am having problems taking direction readings indoors.
• Move away from any potential source of strong magnetism and try taking a reading again. See
“Location” (page E-65).
Whenever you have a sensor malfunction, take the watch to your original retailer or nearest authorized
CASIO distributor as soon as possible.
Altitude Readings
■
Altitude readings produce different results at the same location.
■
Readings produced by the watch are different from the elevation and/or sea level altitude
indications in my area. (Negative sea level altitude values are produced in a location where the
indicated elevation is a positive value.)
E-117
Taking Direction Readings
■
Abnormal magnetism detection is indicated.
• Move away from any potential source of strong magnetism and try
taking a reading again.
• If abnormal magnetism is detected again when you retry, it could mean
that the watch itself has become magnetized. If this happens, continue
to keep away from the source of strong magnetism, perform fi
gure 8
calibration or 3-point calibration, and then try taking a reading again.
For more information, refer to “To perform fi gure 8 calibration” (page E-58),
“To perform 3-point calibration” (page E-60), and “Location” (page E-65).
■
ERR appears on the digital display during sensor reading operations.
There is something wrong with the sensor. This could be due to nearby strong magnetic force. Move
location where magnetism is not present and try again. If, after multiple retries,
ERR
keeps appearing,
contact your original retailer or CASIO service center. See “Location” (page E-65).
■
ERR appears following fi gure 8 calibration or 3-point calibration.
If the screen displays hyphens (
- - -
) followed by the
ERR
(error) indicator, it could mean there is
something wrong with the sensor.
• Wait for about one second for the
ERR
indicator to disappear from the display, and then calibrate the
sensor again.
• If
ERR
continues to appear even after multiple attempts to calibrate, contact your original retailer or
authorized CASIO service center.

Troubleshooting
Time Setting
See “Radio Controlled Atomic Timekeeping” (page E-20) for information about adjusting the time setting
according to a time calibration signal.
■
The current time setting is off by hours.
Your Home City setting may be wrong (page E-34). Check your Home City setting and correct it, if necessary.
■
The current time setting is off by one hour.
If you are using the watch in an area where time calibration signal reception is possible, see “To confi gure
Home City and summer time settings” (page E-34).
If you are using in the watch in an area where time calibration signal reception is not possible, you may
need to change your Home City’s standard time/daylight saving time (DST) setting manually. Use the
procedure under “To change the current time and date settings manually” (page E-36) to change the standard
time/daylight saving time (DST) setting.
Barometric Pressure Readings
■
Following a relative barometric pressure reading, the watch’s second hand points to 9 o’clock.
• The reading value is outside of the allowable measurement range. See page E-48.
• There may be a problem with the sensor. If
ERR
(error) is on the digital display, refer to “Barometric
Pressure, Bearing, Altitude, Temperature, and Depth Readings” (page E-120) for more information.

Illumination Precautions
• The LED that provides illumination loses power after very long use.
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can
cause frequent activation of the auto light switch and illumination of the display. To avoid running down
the battery, disable the auto light switch whenever engaging in activities that might cause frequent
illumination of the display.
• Note that wearing the watch under your sleeve while the auto light switch is enabled can cause
frequent illumination of the display and can run down the battery.
• Illumination may not turn on if the face of the watch is more than 15
degrees above or below parallel. Make sure that the back of your hand
is parallel to the ground.
• Illumination turns off after the preset illumination duration (page E-111), even
if you keep the watch pointed towards your face.
•
Static electricity or magnetic force can interfere with proper operation of
the auto light switch. If illumination does not turn on, try moving the
watch back to the starting position (parallel with the ground) and then tilt
it back towards your face again. If this does not work, drop your arm all
the way down so it hangs at your side, and then bring it back up again.
• You may notice a very faint clicking sound coming from the watch
when it is shaken back and forth. This sound is caused by mechanical
operation of the auto light switch, and does not indicate a problem with
the watch.
E-113
Note
• This watch features a “Full Auto Light”, so the auto light switch operates only when available light is
below a certain level. It does not illuminate the display under bright light.
• The auto light switch is always disabled, regardless of its enabled/disabled setting, when any one of
the conditions below exists.
While any tone (alarm, timer, etc.) is sounding
While the watch is in the Digital Compass Mode and Depth Meter Mode
While a receive operation is in progress
While a hand movement operation is in progress
• If the auto light switch is enabled, display illumination may be delayed if you angle the watch towards
your face while a barometric pressure, altitude, or temperature reading operation is being performed.
To enable or disable the auto light switch
1. In the Timekeeping Mode, pull out the crown.
2. Press
B
fi
ve times. This will cause
AUTO
to appear on the left of the
digital display, along with the fl ashing current auto light switch setting
(
ON
or
OFF
) on the right.
3. Rotate the crown to select either enabled (
ON
) or disabled (
OFF
) for
the auto light switch setting.
4. Push the crown back in.

About the Auto Light Switch
Enabling the auto light switch causes illumination to turn on,
whenever you position your wrist as described below in any mode.
Moving the watch to a position that is parallel to the ground and
then tilting it towards you more than 40 degrees causes
illumination to turn on.
Warning!
•
Always make sure you are in a safe place whenever you are reading the display of the watch
using the auto light switch. Be especially careful when running or engaged in any other activity
that can result in accident or injury. Also take care that sudden illumination by the auto light
switch does not startle or distract others around you.
•
When you are wearing the watch, make sure that its auto light switch is disabled before riding on
a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended
operation of the auto light switch can create a distraction, which can result in a traffi c accident
and serious personal injury.
