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.
Changes in barometric pressure
ー
Changes in temperature caused by
ー
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.

2.
Hold down (E) for at least two seconds.
Release the button when [ALTI] appears
on the display.
This displays the current altitude and
enters the Altitude Offset Mode.
3.
Use (A) and (C) to change the altitude
value to an elevation value obtained from
another source.
Setting range: -10,000 to 10,000 meters
(or -32,800 to 32,800 feet)
Setting unit: 1 meter (or 5 feet)
Holding down (A) or (C) scrolls through
●
settings at high speed.
To return the altitude setting to its initial
●
factory default, press (A) and (C) at the
