Module No. 3553
Troubleshooting
Signal Reception (Time Calibration Signal)
Q1The watch cannot perform a receive operation.
Is the watch’s battery charged?
Signal reception is not possible while battery power is low. Keep the watch exposed to light until it recharges sufficiently.
Is the watch in the Timekeeping Mode or World Time Mode?
Time signal receive is not possible unless the watch is in the Timekeeping Mode or World Time Mode. Enter the Timekeeping Mode or World Time Mode.
Is your Home City setting correct for your location?
The watch will not indicate the correct time if the Home City setting is wrong. Change your Home City setting so it correctly reflects your location.
After checking the above, the watch still cannot perform a receive operation.
Time calibration signal reception is not possible under the conditions described below.
When watch is at Level 2 power saving
Timer countdown operation in progress
If successful reception is not possible for some reason, you can adjust the time and day settings manually.
Q2The signal receive operation always fails.
Is the watch in a location that is appropriate for signal reception?
Check your surroundings and move the watch to a location where signal reception is better.
Did you avoid touching the watch while the receive operation was in progress?
Minimize movement of the watch and do not perform any watch operation while a receive operation is in progress.
Is there an alarm configured to sound during the same period that the signal receive operation is performed?
Receive stops if an alarm operation starts while it is being performed. Disable the alarm.
Is the signal transmitter in your area transmitting a signal?
The transmitter of the time calibration may not be transmitting a signal.
Try again later.
Q3Signal reception should have been successful, but the watch’s time and/or day is wrong.
Adjust time and day settings manually.
Altitude Measurement
Q1Readings produce different results at the same location.
Watch readings are different from altitude information available from other sources.
Correct altitude readings are not possible.
Relative altitude is calculated based on changes in barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken 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, it is recommended that you regularly calibrate its readings in accordance with local altitude (elevation) indications.
Q2[ERR] appears during measurement.
There may be a problem with the sensor. Try taking another measurement.
If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.
Digital Compass
Q1The entire display is flashing.
Abnormal magnetism has been detected. Move away from any potential source of strong magnetism and try taking a reading again.
If the display flashes again, it could mean that the watch itself has become magnetized. Move away from any potential source of strong magnetism, perform 2-point calibration, and then try taking a reading again.
Q2[ERR] appears during measurement.
There is a problem with the sensor or there may be a source strong magnetic force nearby. Move away from any potential source of strong magnetism and try taking a reading again. If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.
Q3[ERR] appears following 2-point calibration.
[ERR] on the display could indicate a sensor problem.
If [ERR] disappears after about one second, try performing 2-point calibration again.
If [ERR] keeps appearing after multiple attempts, contact a CASIO service center or your original retailer.
Q4Direction information indicated by the watch is different from that indicated by a backup compass.
Move away from any potential source of strong magnetism, perform 2-point calibration, and then try taking a reading again.
Q5Readings at the same location produce different results.
Cannot take readings indoors.
Move away from any potential source of strong magnetism and try taking a reading again.
Barometric Pressure Measurement
Q1The barometric pressure differential graphic is not displayed after barometric pressure measurement.
The barometric pressure differential graphic is not displayed if the barometric pressure measurement value exceeds the allowable measurement range (260hPa to 1,100hPa) or if the barometric pressure differential exceeds ±10hPa. If [ERR] is displayed, there may be a problem with the sensor.
Q2[ERR] appears during measurement.
There may be a problem with the sensor. Try taking another measurement. If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.
Temperature Measurement
Q1[ERR] appears during measurement.
There may be a problem with the sensor. Try taking another measurement. If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.
World Time
Q1The time for a World Time City is not correct.
The summer time setting (standard time/summer time) may be wrong.
Alarm and Hourly Time Signal
Q1An alarm does not sound.
Is the watch’s battery charged?
Keep the watch exposed to light until it recharges sufficiently.
Other than the above.
The alarm’s settings may not be configured. Configure the alarm settings.
Q2The hourly time signal does not sound.
Is the watch’s battery charged?
Keep the watch exposed to light until it recharges sufficiently.
Other than the above.
The hourly time signal may be disabled. Enable the hourly time signal.
Charging
Q1The watch does not work even though it is exposed to light.
The watch stops operating whenever the battery goes dead. Keep the watch exposed to light until it recharges sufficiently.
Q2[H], [M], and [L] are flashing on the display.
The watch is in the charge recovery mode. Wait until the recovery process is complete (about 15 minutes). The watch will recover more quickly if you place it in a brightly lit location.
If a signal receive operation, alarm, hourly time signal, illumination and/or other power-intensive functions are used within a short period of time, the charge level of the battery will drop and cause the watch to go into a charge recovery mode. Function availability will be temporarily limited, but functionality will return after the battery recovers.
Q3[CHG] is flashing on the display.
The charge level of the watch is extremely low. Immediately expose the watch to light to charge it.
