Q2
The 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.
l
Appropriate Signal Reception Location
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.
l
Turning Off an Alarm or the Hourly
Time Signal
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.
Q3
Signal reception should have been
successful, but the watch’s time and/
or day is wrong.
Is the indicated time off by one hour or by
30 minutes?
The watch may be using the wrong time
offset. Specify the area you want to use as
your Home City.
l
Is the indicated hour and/or minute wrong?
The hour hand and/or minute hand may
be out of alignment. Perform the
procedure under “Hand Alignment
Adjustment” to auto adjust hour and
minute hand alignment.
l
After checking the above, the time and/or
day settings is still wrong.
Adjust time and day settings manually.

Time Setting
Altitude Measurement
Q1
Readings 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.
l
Calibrating Altitude Readings (Offset)
Q2
Following a relative altitude reading,
the watch’s second hand points to 9
o’clock.
The second hand will move to 9 o’clock if a
reading is outside the allowable altitude
measurement range (-700 m to 10,000 m
(-2,300 to 32,800 feet)). If [ERR] is displayed,
there may be a problem with the sensor.
l
Checking the Altitude Differential from a
Reference Point
Q3
[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
Q1
The entire display is flashing.
Abnormal magnetism has been detected.
Move away from any potential source of
strong magnetism and try taking a reading
again.
l
Digital Compass Reading Precautions
●
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.
l
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.
l
Digital Compass Reading Precautions
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.
Q4
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 2-point
calibration, and then try taking a reading
again.

Digital Compass Reading Precautions
Q5
Readings 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.
