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-24
You are in an area where signal
reception is not possible for
some reason.
See “Approximate Reception Ranges”.
E-21
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 gured for auto receive of the time calibration signal (page E-23), which will
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-36).
E-125
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
confi gure World Time City and summer time settings” (page E-113) for more information.
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-15). Keep the watch exposed to light until it
recharges suffi ciently.
■
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 recovery mode. The
watch is in the charge recovery mode when
RECOVER
is fl ashing on the digital display. The charge
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-17).
•
A fl ashing
CHARGE
indicator means that the charge level of the watch has suddenly dropped.
Immediately expose the watch to light to charge it.
E-124
Whenever you have a sensor malfunction, take the watch to your original retailer or nearest authorized
CASIO distributor as soon as possible.
Barometric Pressure Readings
■
Following a barometric pressure differential reading, the watch’s small hand points to 12 o’clock.
•
The reading value is outside of the allowable measurement range. See page E-79.
•
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.
E-123
■
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. Move
location where magnetism is not present and try again. If, after multiple retries,
ERR
keeps appearing,
contact your original retailer or CASIO service center. See “Location” (page E-57).
■
ERR appears following fi gure 8 calibration or 3-point 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 any potential source of strong magnetism, perform fi gure 8 calibration or 3-point
calibration, and then try taking a reading again. For more information, refer to “To perform fi gure 8
calibration” (page E-48), “To perform 3-point calibration” (page E-50), and “Location” (page E-57).
■
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-57).
■
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-57).
E-122
■
I can’t get correct altitude readings.
Relative altitude is calculated based on changes in barometric pressure measurement by the watch’s
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-63).
■
Following a relative altitude reading, the watch’s small hand points to 12 o’clock.
•
The reading value is outside of the allowable measurement range. See page E-61.
•
This could indicate sensor error. If
ERR
(error) is on the digital display, refer to “Direction, Altitude,
Barometric Pressure, and Temperature Readings” (page E-124) 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 fi gure 8
calibration or 3-point calibration, and then try taking a reading again.
For more information, refer to “To perform fi gure 8 calibration” (page E-48),
“To perform 3-point calibration” (page E-50), and “Location” (page E-57).

Troubleshooting
Time Setting
See “Radio Controlled Atomic Timekeeping” (page E-20) 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-36). 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 gure
Home City and summer time settings” (page E-36).
If you are using 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-38) 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.)
