Troubleshooting
Time Setting
■
Why is the current time setting off by a couple of hours?
Your Home City setting may be wrong (page E-17). Check your Home City setting and
correct it, if necessary.
■
Why is the current time setting 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-22) to change the standard time/daylight saving time (DST) setting.
Sensor modes
■
Why can’t I change the temperature unit setting?
The temperature unit setting is always Celsius (
°C
) whenever
TOKYO
is selected as
the Home City. In this case, the setting cannot be changed.

■
Why does “ERR” appear 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 digital
display and sensor operations will be disabled.
Direction Reading and
Temperature Measurement
• If
ERR
appears while a measurement operation is being performed in a sensor
mode, restart the measurement. If
ERR
appears on the digital display again, it can
mean there is something wrong with the sensor.
• If
ERR
keeps appearing during measurement, it can mean there is a problem with
the applicable sensor.
E-72
■
Why does “ERR” appear on the digital 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.
■
What causes incorrect direction readings?
• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-36).
• 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.
E-73
■
What causes different direction readings to produce different results 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.
■
Why am I having 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.
E-74
Battery
■
Why is the low battery alert fl ashing?
Battery power is low. Watch operations are disabled while
the low battery alert is fl ashing on the digital display.
If the low battery alert disappears after battery power
recovers but then starts to fl ash again after a short while,
it means that you need to have the watch’s battery
replaced.
