Troubleshooting
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.

Q2
[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.

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.

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.

Barometric Pressure
Measurement
Q1
The barometric pressure differential
graphic is not displayed after
barometric pressure measurement.
The barometric pressure differential graphic is
not displayed if the barometric pressure
measurement value exceeds the allowable
measurement range (260hPa to 1,100hPa) or
if the barometric pressure differential exceeds
±10hPa. If [ERR] is displayed, there may be a
problem with the sensor.

Q2
[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.
Temperature Measurement
Q1
[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.
World Time
Q1
The time for a World Time City is not
correct.
The summer time setting (standard time/
summer time) may be wrong.
