Calibrating Compass Readings
In order to ensure that the watch is performing
direction measurements correctly, be sure to
perform figure 8 calibration whenever the
measurement results produced by the watch
are different from readings produced by
another compass. You should also perform
figure 8 calibration before setting out on a
climb.
●
Note that accurate compass readings
and/or calibration will not be possible in an
area where strong magnetism is present.

Digital Compass Reading Precautions
1. Display the current time screen.

Watch Mode
2. Use (A) and (D) to select [COMPASS].
3. Press (C).
4. Hold down (A) for at least two seconds.
This displays the direction measurement
setting screen.
5. Use (A) and (D) to move the pointer to
[FIGURE 8].
6. Press (C).
This displays the figure 8 calibration
screen.
When the screen shown above appears,
move your arm in a figure 8 pattern as
shown in the illustrations below.
●
Allow your wrist to twist.
●
Keep your arm as far as possible from
your body as you move it.
●
After calibration is successful, a check
mark appears for a few seconds, and
then the setting screen re-appears.
Note
●
The message [FAILED RETRY?]
appears on the display if calibration
fails.
Press (A) or (D) to select [YES] (Re-
calibrate) or [NO] (Stop calibration),
and then press (C).
●
To return to the direction measurement
setting screen during the above
procedure, press (E).
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.
l
Magnetic North and True North
●
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.
