• 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 or Level 2, the Digital Compass Mode,
Barometer/Thermometer Mode, or Altimeter 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.
Whenever you have a sensor malfunction, be sure to take the watch to
your original dealer or nearest authorized CASIO distributor as soon as
possible.
