E-103
■
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-16
You are in an area where signal
reception is not possible for
some reason.
See “Approximate Reception Ranges”. E-15
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-17), 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-28).
E-102
• Even if battery power is at Level 1 (
H
) or Level 2 (
M
), the Digital Compass Mode, Barometer/
Thermometer Mode, or Altimeter Mode sensor may become momentarily disabled if there is not enough
voltage available to power it suffi ciently. In this case,
ERR
will appear on the display. This does not
indicate malfunction, and sensor operation should resume once battery voltage returns to its normal
level.
• If
ERR
keeps appearing during a reading operation, it could mean there is a problem with the
applicable sensor.
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-91) 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-10). Continue exposing the watch to light
until the battery power indicator shows “
H
” or “
M
”.

Direction, Altitude, Barometric Pressure, and Temperature Readings
■
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.
■
“ERR” appears on the display while I am using a sensor.
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 display and sensor operations will be disabled.

• If
ERR
appears while a reading operation is being performed in a sensor mode, restart the operation. If
ERR
appears on the display again, it can mean there is something wrong with the sensor.

■
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-37) and “Location” (page E-42).
■
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-42).
■
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-42).
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
■
The barometric pressure differential pointer does not appear on the display when I enter the
Barometer/Thermometer Mode.
• This could indicate sensor error. Try pressing
B
again.
• The barometric pressure differential pointer is not displayed when the displayed current barometric
value is outside of the allowable measurement range (260 to 1,100 hPa).
E-99
■
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 altimeter of this watch for mountain climbing or other activities, it is highly recommended
that you check a map, local altitude indications, or some other source for your current correct altitude and
regularly calibrate the altimeter with the latest information.
For more information, see “To specify a reference altitude value” (page E-61).
Taking Direction Readings
■
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-42).
■
ERR appears following bidirectional calibration.
If the screen displays dashes (
- - -
) 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.

Troubleshooting
Time Setting
See “Radio Controlled Atomic Timekeeping” (page E-14) 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-28). 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-28).
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-30) 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.)
