Digital Compass
Q1
The symbol   is shown on the
display.
Abnormal magnetism has been detected.
Move away from any potential source of
strong magnetism and try taking a reading
again.
●
If   appears again, it could mean that the
watch body has become magnetized. Move
away from any potential source of strong
magnetism, perform direction calibration,
and then try taking a reading again.

Q2
[ERROR] 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 [ERROR] keeps appearing after
multiple measurement attempts, contact a
CASIO service center.

Q3
[ERROR] appears on the display
following direction calibration.
If [- - -] is followed by [ERROR] on the display,
it could mean there is something wrong with
the sensor.
●
If [ERROR] disappears after about one
second, try performing bidirectional
calibration again.
●
If [ERROR] continues to appear even after
multiple attempts, contact a CASIO service
center.
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 bidirectional
calibration, and then try taking a reading
again.
