Auto light switch precautions
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-45), 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-49
Button Operation Tone
When enabled, the button operation tone sounds any time you press one of the watch’s buttons. You can
enable or disable the button operation tone as desired.
Even if you disable the button operation tone, the alarm, Hourly Time Signal, and Countdown Timer
Mode alarm all operate normally.
To enable or disable the button operation tone
1. In the Timekeeping Mode, hold down
A
until
ADJ
appears in the upper display.
When you release
A
(after ADJ appears), city code will be fl ashing in the upper display.
2. Use
D
to cycle through settings on the upper display until the current
button operation tone setting (
MUTE
or
KEY
) is shown.
See the sequence in step 2 of the procedure under “To change the
current time and date settings” (page E-16) for information about
how to scroll through setting screens.
3. Press
E
to toggle the button operation tone setting between enabled (
KEY
) and disabled (
MUTE
).
4. After the setting is the way you want, press
A
to exit the setting screen.

Low Battery Indication
A low battery indicator appears on the display when battery power is low. Have the batteries replaced as
soon as possible.
Note
For information about battery life guidelines and supported battery types, see the product
specifi cations.
See “Speci cations” (page E-55).
The conditions below are in effect while the low battery indicator is fl ashing.
All hands are stopped.
Except for the low battery indicator, all other display functions are
disabled.
Watch tones are disabled.
Display illumination is disabled.
Watch operations are disabled.
Note
Sequentially or repeatedly performing sensor, light, alarm, and other power intensive operations
over a short period can cause a sudden drop in battery power, which will make the low battery
indicator fl ash. Even though the low battery indicator may disappear and watch functions may
become re-enabled, battery replacement is recommended.

Troubleshooting
Time Setting
The current time setting is off by a couple of hours.
Your Home City setting may be wrong (page E-14). Check your Home City setting and correct it, if
necessary.
The current time setting is off by one hour.
You may need to change your Home City’s standard time/daylight saving time (DST) setting. Use the
procedure under “To change the current time and date settings” (page E-16) to change the standard time/
daylight saving time (DST) setting.
World Time Mode
The time for my World Time City is off in the World Time Mode.
This could be due to incorrect switching between standard time and daylight saving time.
See “To confi gure World Time City and summer time settings” (page E-36) for more information.
E-52
Batteries
The low battery indicator is fl ashing on the digital display.
The watch’s battery power is low. Have the batteries replaced as soon as
possible.
See “Low Battery Indication” (page E-50).

E-53
Bearing and Temperature Readings
The temperature unit setting won’t change.
The temperature unit setting is always Celsius (
°C
) whenever
TOKYO
is selected as the Home City. In
this case, the setting cannot be changed.
“ERR” appears while a sensor operation is in progress.
Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal
circuitry. When this happens,
ERR
(error) will appear on the upper display and sensor operations will be
disabled.
Digital Compass
Operation
Temperature
Measurement
If
ERR
appears while a measurement operation is being performed in a sensor mode, restart the
measurement. If
ERR
appears on the upper display again, it can mean there is something wrong with
the sensor.
If
ERR
keeps appearing during measurement, it could mean there is a problem with the applicable
sensor.
E-54
“ERR” appears on the upper display following bidirectional calibration.
If
- - -
appears and then changes to
ERR
(error) on the calibration screen, it means that there is something
wrong with the sensor.
If
ERR
disappears after about one second, try performing the calibration again.
If
ERR
keeps appearing, contact your original dealer or nearest authorized CASIO distributor to have
the watch checked.
Whenever you have a sensor malfunction, take the watch to your original dealer or nearest authorized
CASIO distributor as soon as possible.
Incorrect direction readings.
Incorrect bidirectional calibration. Perform bidirectional calibration (page E-25).
Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel
beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move
away from large metal objects and try again.
Different results produced by direction readings taken at the same location.
Magnetism generated by nearby high-tension wires is interfering with detection of terrestrial magnetism.
Move away from the high-tension wires and try again.
Problems taking direction readings indoors.
A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism
readings. Move away from the object causing the interference or take the direction reading outdoors.
Indoor direction readings are particularly diffi cult inside ferro-concrete structures.
Remember that you will not be able to take direction readings inside of trains, airplanes, etc.
