Calibrating Compass Readings; Setting Up For True North Readings (Magnetic Declination Calibration) - Casio 3452 Operation Manual

Calibrating Compass
Readings
Perform 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.
Digital Compass Reading Precautions
l
1.
Press (A).
This displays the Digital Compass Mode
setting screen.
2.
Rotate the rotary switch to move the
pointer to [CALIBRATION].
3.
Press the rotary switch.
4.
While keeping the watch horizontal, press
(D).
This starts calibration of the first point,
which causes [PLEASE WAIT] to appear
on the display. [ROTATE 180°] will appear
when calibration is successful.
5.
Keeping the LCD of the watch pointing
upwards, rotate it 180 degrees. Be as
exact as possible.
6.
While keeping the watch horizontal, press
(D).
This starts calibration of the second point,
which causes [PLEASE WAIT] to appear
on the display. [TURN OVER] will appear
when calibration is successful.

7.
Turn the watch over so the LCD is pointing
at the ground.
8.
While keeping the watch horizontal, press
(D).
This starts calibration of the third point,
which causes [PLEASE WAIT] to appear
on the display. [SUCCESSFUL] will
appear when calibration is successful. A
few seconds later, the watch will return to
the Digital Compass screen.
Note
If calibration fails, the message
●
[FAILED RETRY?] will appear. To retry
calibration, press the rotary switch.
Press (C) to stop calibration.
Setting Up for True North
Readings (Magnetic
Declination Calibration)
Rotary Switch
If you want the watch to indicate true north
instead of magnetic north, you need to specify
the current 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°.4' (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.
Ground
1.
Press (A).
This displays the Digital Compass Mode
setting screen.
2.
Rotate the rotary switch to move the
pointer to [MAGNETIC DECLINATION].
3.
Press the rotary switch.
4.
Rotate the rotary switch to configure the
magnetic declination direction and angle
settings.
Setting range: 90° west to 90° east
[0° (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 [0° (OFF)], press
●
(D).

the steps below.
A Press (C).
B Rotate the rotary switch to select
whether or not you want to save the
current settings.
[YES]: Current settings saved
[NO]: Current settings not saved
Pressing (C) enables configuration of
●
the magnetic declination direction and
angle settings.
