Troubleshooting
Time Setting
See “Radio Controlled Atomic Timekeeping” (page E-21) 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-40). 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 configure Home City settings” (page E-40).
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-45) to change the standard time/daylight saving
time (DST) setting.
E-111
Sensor modes
■ I can’t 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.
■ “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.
E-112
• If ERR appears while a measurement operation is being performed in a sensor
mode, restart the measurement. If ERR appears on the display again, it can mean
there is something wrong with the sensor.
• Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass/
Thermometer Mode, sensor may be disabled if there is not enough voltage
available to power it sufficiently. 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 measurement, it could mean there is a problem with
the applicable sensor.
■ ERR appears on the display after I perform bidirectional calibration or
northerly 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.
E-113
■ ERR appears on the display after I perform northerly calibration.
The ERR message indicates there may be some problem with the sensor. The ERR
message also may be due to movement of the watch while the calibration procedure
is being performed. Try performing calibration again, taking care to ensure that the
watch is not moved.
If this does not solve the problem, the problem may be due to some nearby source of
terrestrial magnetism. Try performing the calibration procedure again from the
beginning.
Whenever you have a sensor malfunction, take the watch to your original dealer or
nearest authorized CASIO distributor as soon as possible.
E-114
■ What causes incorrect direction readings?
• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-58).
• 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. Note that digital compass operation cannot be performed inside a train,
boat, etc.
■ 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.
E-115
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-88) 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-14). Continue
exposing the watch to light until the battery power indicator shows “H” or “M”.

Time Calibration Signal
The information in this section applies only when LISBON, LONDON, MADRID,
PARIS, ROME, BERLIN, STOCKHOLM, ATHENS, MOSCOW, HONG KONG,
BEIJING, HONOLULU, ANCHORAGE, VANCOUVER, LOS ANGELES,
EDMONTON, DENVER, MEXICO CITY, CHICAGO, NEW YORK, HALIFAX,
ST. JOHN’S, SEOUL, or TOKYO is selected at the Home City. You need to adjust the
current time manually when any other city is selected as the Home City.
E-117
■ 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-26
You are in an area where signal
reception is not possible for
some reason.
See “Approximate Reception Ranges”. E-23
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.

E-118
■ The current time setting changes after I set it manually.
You may have the watch configured for Auto Receive of the time calibration signal
(page E-28), 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-40).
■ 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.
E-26
If you are unable to receive the time calibration
signal, change the standard time/daylight saving
time (DST) setting manually.
E-43
E-119
■ Auto Receive is not performed or you cannot perform Manual Receive.
Possible Cause Remedy Page
The watch is not in the
Timekeeping Mode or World
Time Mode. Auto receive is performed only while the watch is
in the Timekeeping Mode or World Time Mode.
Switch to either of these two modes.
E-36
Your Home City setting is wrong.
Check your Home City setting and correct it, if
necessary.
E-40
There is not enough power for
signal reception.
Expose the watch to light to charge it. E-12
