Operation Guide 5269

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.

E-70

■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 andTemperature 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-71

■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.

■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 difficult inside ferro-concrete structures. Remember that you will not be able to take direction readings inside of trains, airplanes, etc.

Battery■Why is the low battery alert flashing?

Battery power is low. Watch operations are disabled while the low battery alert is flashing on the digital display.

If the low battery alert disappears after battery power recovers but then starts to flash again after a short while, it means that you need to have the watch’s battery replaced.
