Calibrating Compass Readings

Perform 2-point calibration whenever you
notice the watch's compass readings are
different from those of another compass, or
before setting out on a climb or trek.
Note that accurate compass readings
●
and/or calibration will not be possible in an
area where strong magnetism is present.

3.
While keeping the watch horizontal, press
(C).
This starts calibration of the first point,
which causes [- - -] to appear on the
display. [Turn 180°] appears on the
display when calibration is successful,
and the three-line graphic direction
pointer flashes at 6 o'clock. One second
later, [CALIBRATION] [-2-] appears on
the display.
4.
Rotate the watch 180 degrees, taking care
to be as exact as possible.
5.
Press (C).
This starts calibration of the second
●
point, which causes [- - -] to appear on
the display.
When calibration is successful, [OK]
●
appears on the display and the watch
returns to the Digital Compass screen.
Note
[ERR] [-1-] appears if calibration fails
●
for some reason. If this happens,
restart the above procedure from step
3.
Setting Up for True North Readings
(Magnetic Declination Calibration)
If you want the watch to indicate true north
instead of magnetic north, you need to specify
your current location's magnetic declination
direction (east or west) and declination angle.
Magnetic North and True North
l
The magnetic declination angle value can
●
be set in 1° (degree) units only. Use a value
that is closest to the angle you want to set.
Example: For an angle of 7.4°, set 7°.
Example: For an angle of 7°40' (7 degrees,
40 minutes), set 8°.
Note
Magnetic declination angles (east or
●
west) and angle degree values for
specific locations can be found on
geographic maps, mountain climbing
maps, and other maps that include
contour lines.
