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.

Magnetic North and True North
●
There are actually two types of north:
magnetic north and true north.
Magnetic north: North indicated by the needle
of a compass
True north: Direction to the North Pole
Graphic direction pointer
As shown in the illustration below, magnetic
north and true north are not the same.
Note
Use (A) (East) and (C) (West) to change
the magnetic declination direction and
angle.
Holding down (A) or (C) scrolls through
●
settings at high speed.
Setting range: 90° west to 90° east
[OFF]: Magnetic north
[E]: East declination (Magnetic north is
east of true north.)
[W]: West declination (Magnetic north is
west of true north.)
To return the setting to [OFF], press (A)
●
and (C) at the same time.
