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
Q2
[-----] appears on the display
following altitude differential
measurement.
[-----] appears when the altitude differential is
outside the allowable measuring range
(±3,000 m). If [ERROR] appears on the
display, there may be a problem with the
sensor.
l
Setting a Reference Altitude and Taking
Relative Altitude Readings
Q3
[ERROR] appears during

There may be a problem with the sensor. Try
taking another measurement. If [ERROR]
keeps appearing after multiple measurement
attempts, contact a CASIO service center.
