■
The digital display fl ashes at one-second intervals.
• This occurs during a digital compass operation when abnormal
magnetism is detected. The watch hands continue to move normally.
• Move the watch away from magnetic accessories, electric devices,
computers, and any other devices that generate strong magnetism,
and try performing the sensor operation again.
• Try performing the operation again. If abnormal magnetism is not
indicated again, you will be able to perform the operation normally.
• If abnormal magnetism detection is indicated again, it may mean that
the watch case may have become magnetized or that magnetism
conditions are completely different from those where you last
performed bidirectional calibration. Perform bidirectional calibration
using the procedure under “To perform bidirectional calibration” (page
E-26).
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-26).
• 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.
■
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.
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 specify standard time or daylight saving time (DST) for a city” (page E-41) for more information.
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 batteries replaced.
