Calibrating Compass Readings; Calibrating Compass Readings (Bidirectional Calibration); Setting Up For True North Readings (Magnetic Declination Calibration) - Casio 5470 Operation Manual

Note
Normally the Compass Mode
●
indicates magnetic north. You can
also configure settings to indicate
true north.

Magnetic North and True North

After the initial reading is displayed,
●
the watch will continue to take
readings about every second for
about the next 60 seconds. The
watch will return to the Timekeeping
Mode automatically about 60
seconds after you press (C).
Auto Light will not illuminate the face
●
while a compass operation is in
progress.
If an alarm or other beeper sounds,
●
or if you turn on illumination by
pressing (L) while a compass
operation is in progress, the
compass operation will be
suspended momentarily. The
compass operation will resume
when the beeper stops or
illumination turns off.
Aligning a map with actual
●
surroundings (setting a map)
Setting a map means to align the map so the
directions indicated on it are aligned with the
actual directions of your location. Once you
set a map, you can more easily get a grasp of
the relationship between map markings and
actual geographic contours. To set a map with
this watch, align north on the map with the
north indication of the watch. Once you set the
map, you can compare your bearing on the
map with your surroundings, which will help
you determine your current location and
destination.
Note that map reading skills and experience
●
are required to determine your current
location and destination on a map.

Readings

Calibrating Compass Readings

(Bidirectional Calibration)
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.
Pull out the crown.
2.
While keeping the watch horizontal, press
(C).
This starts calibration of the first point,
which causes [o WAIT] to appear on the
display. If calibration is successful,
indicators will appear on the display in the
following sequence: [OK] n [Turn 180°]
n [p 2].
3.
Rotate the watch 180 degrees, taking care
to be as exact as possible.
4.
Press (C).
This starts calibration of the second point,
which causes [p WAIT] to appear on the
display. [OK] will appear on the display if
calibration is successful.
5.
Push the crown back in to complete the
setting operation.
Note
[ERR] will appear if calibration fails
●
for some reason. If this happens,
restart the above procedure from
step 1.
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
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
Crown
include contour lines.
1.
Pull out the crown.
2.
Press (B).
3.
Rotate the crown to change the magnetic
declination direction and angle settings as
desired.
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
●
(A) and (C) at the same time.
