Calibrating Altitude
Readings (Offset)
To minimize the difference between locally
indicated and measured values, you should
update the reference altitude value (offset)
before setting off and during treks or any other
activities where you take altitude readings.
Also, you can ensure accurate measurements
by checking a map local altitude indications or
some other source for your current location’s
altitude, and regularly calibrating watch
readings with the latest information while
mountain climbing.
Note
●
You can find out the altitude at your
current location from signs, maps, on
the Internet, etc.
●
Differences between actual altitude
and watch readings can be caused by
the factors below.
ー
Changes in barometric pressure
ー
Changes in temperature caused by
variations in barometric pressure
and by elevation
●
Though altitude readings can be taken
without calibration, doing so may
produce readings that are very
different from indications by altitude
markers, etc.
1.
Enter the Altimeter Mode.
l
2.
Pull out the crown.
This displays the current altitude and
enters the Altitude Offset Mode.
Crown
3.
Rotate the crown to calibrate the
displayed value to that of a local altitude
(elevation) marker.
Setting range: -3,000 to 10,000 meters
Setting unit: 1 meter
●
To return the altitude setting to its initial
factory default, press (A) and (C) at the
same time.
4.
Push the crown back in to complete the
setting operation.
Note
●
If you do not perform any operation for
about two minutes after pulling out the
crown, crown operations will
automatically become disabled. If that
happens, push the crown back in and
then pull it out again.
Checking the Altitude
Differential from a Reference
Point
After you set a reference altitude, the second
hand of the watch will indicate the difference
between your current altitude and the
reference altitude. This makes it easy to
measure the altitude difference between two
points while climbing or trekking.

Setting the Altitude Differential
Measurement Range
1.
Enter the Altimeter Mode.
l
2.
Pull out the crown.
This displays the altitude for your current
location.
Crown
3.
Press (B) twice.
This displays the altitude differential
measurement range.
4.
Rotate the crown to select either [100m] or
[1000m].
[100m]: ±100 meters (±328 feet) in 5-
meter (16-foot) units
[1000m]: ±1000 meters (±3280 feet) in
50-meter (164-foot) units
5.
Push the crown back in to complete the
setting operation.
