Troubleshooting
Time Setting
See “Radio Controlled Atomic Timekeeping” (page E-19) for information about adjusting the time setting
according to a time calibration signal.
■
The current time setting is off by hours.
Your Home City setting may be wrong (page E-34). Check your Home City setting and correct it, if
necessary.
■
The current time setting is off by one hour.
If you are using the watch in an area where time calibration signal reception is possible, see “To confi
Home City and summer time settings” (page E-34).
If you are using in the watch in an area where time calibration signal reception is not possible, you may
need to change your Home City’s standard time/daylight saving time (DST) setting manually. Use the
procedure under “To change the current time and date settings manually” (page E-36) to change the
standard time/daylight saving time (DST) setting.
Altitude Readings
■
Altitude readings produce different results at the same location.
■
Readings produced by the watch are different from the elevation and/or sea level altitude
indications in my area. (Negative sea level altitude values are produced in a location where the
indicated elevation is a positive value.)
E-105
■
I can’t get correct altitude readings.
Relative altitude is calculated based on changes in barometric pressure measurement by its pressure
sensor. This means that barometric pressure changes can cause readings taken at different times 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, you need to be sure to perform regular
calibration in accordance with the local altitude (elevation) indications.
For more information, see “To specify a reference altitude value” (page E-57).
■
Following a relative altitude reading, the watch’s second hand points to 9 o’clock.
• The reading value is outside of the allowable measurement range. See page E-55.
• This could indicate sensor error. If
ERR
(error) is on the digital display, refer to “Direction, Altitude,
Barometric Pressure, and Temperature Readings” page E-107) for more information.
Taking Direction Readings
■
Abnormal magnetism detection is indicated.
• Move away from any potential source of strong magnetism and try
taking a reading again.
• If abnormal magnetism is detected again when you retry, it could mean
that the watch itself has become magnetized. If this happens, continue
to keep away from the source of strong magnetism, perform
bidirectional calibration, and then try taking a reading again. For more
information, refer to “To perform bidirectional calibration” (page E-48)
and “Location” (page E-51).
E-106
■
ERR appears on the digital display during sensor reading operations.
There is something wrong with the sensor. This could be due to nearby strong magnetic force. Contact
your original retailer or CASIO service center See “Location” (page E-51).
■
ERR appears following bidirectional calibration.
If the screen displays hyphens (
- - -
) followed by the
ERR
(error) indicator, it could mean there is
something wrong with the sensor.
• Wait for about one second for the
ERR
indicator to disappear from the display, and then calibrate the
sensor again.
• If
ERR
continues to appear even after multiple attempts to calibrate, contact your original retailer or
CASIO service center.
■
The direction information indicated by the watch is different from that indicated by a backup
compass.
• Move away from and potential source of strong magnetism, perform bidirectional calibration, and then
try taking a reading again. For more information, refer to “To perform bidirectional calibration” (page
E-48) and “Location” (page E-51).
■
Direction readings produce different results at the same location.
• Move away from any potential source of strong magnetism and try taking a reading again. See
“Location” (page E-51).
■
I am having problems taking direction readings indoors.
• Move away from any potential source of strong magnetism and try taking a reading again. See
“Location” (page E-51).
Whenever you have a sensor malfunction, take the watch to your original retailer or nearest authorized
CASIO distributor as soon as possible.
E-107
Barometric Pressure Readings
■
Following a relative barometric pressure reading, the watch’s second hand points to 9 o’clock.
• The reading value is outside of the allowable measurement range. See page E-74.
• There may be a problem with the sensor. If
ERR
(error) is on the digital display, refer to “Direction,
Altitude, Barometric Pressure, and Temperature Readings” for more information.
Direction, Altitude, Barometric Pressure, and Temperature Readings
■
ERR appears on the digital display during sensor reading operations.
This indicates that there is a problem with the sensor, making sensor readings impossible.
• If the error is indicated while a reading operation in progress, restart the operation. If
ERR
appears
again, it could mean there is something wrong with the sensor.
• If
ERR
appears frequently, it could mean that the sensor is faulty. Contact your original retailer or
CASIO service center
■
I can’t change the temperature, barometric pressure, and altitude display units.
When
TYO
(Tokyo) is selected as the Home City, the altitude unit is set automatically to meters (m), the
barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These settings
cannot be changed.
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

Charging
■
The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 5 (page E-14). Keep the watch exposed to light until
it recharges suffi
■
RECOVER is fl ashing on the digital 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.
Note
• Performing repeated illumination and/or sensor reading operations over a short time period can cause
a sudden drop in watch’s charge. This will cause the watch to enter the charge recover mode. The
watch is in the charge recovery mode when
RECOVER
is fl
recovery mode is the same as a low battery charge state, access to some functions is limited while the
watch charge is recovering. Normal operation will resume after recovery is complete. For more
information, refer to “Power Recovery Mode” (page E-16).
• A fl
CHARGE
indicator means that the charge level of the watch has suddenly dropped.
Immediately expose the watch to light to charge it.

■
The display shows the ERR indicator when I check the result of the latest receive operation.
Possible Cause Remedy Page
• You are wearing or moving the
watch, or performing a button
operation during the signal
receive operation.
• The watch is in an area with
poor reception conditions.
Keep the watch in an area where reception conditions are good
while the signal receive operation is performed.
E-21
You are in an area where signal
reception is not possible for
some reason.
See “Approximate Reception Ranges”. E-20
The calibration signal is not
being transmitted for some
reason.
• Check the website of the organization that maintains the time
calibration signal in your area for information about its down times.
• Try again later.

■
The current time setting changes after I set it manually.
You may have the watch confi
cause the time to be adjusted automatically according to your currently selected Home City. If this results
in the wrong time setting, check your Home City setting and correct it, if necessary (page E-34).
E-110
■
The current time setting is off by one hour.
Possible Cause Remedy Page
Signal reception on a day for
switching between standard
time/daylight saving time (DST)
may have failed for some reason.
Perform the operation under “To get ready for a receive operation”.
The time setting will be adjusted automatically as soon as signal
reception is successful.

If you are unable to receive the time calibration signal, change the
standard time/daylight saving time (DST) setting manually.
E-36
■
Auto receive is not performed or you cannot perform manual receive.
Possible Cause Remedy Page
The watch is not in the
Timekeeping Mode.
Auto receive is performed only while the watch is in the Timekeeping
Mode. Enter the Timekeeping Mode.

Your Home City setting is wrong. Check your Home City setting and correct it, if necessary. E-34
There is not enough power for
signal reception.
