• You can turn off (OFF) magnetic declination correction (which effectively
makes the magnetic declination angle: 0°) by pressing A and C at the
same time.
• The illustration, for example, shows the value you should input and the
direction setting you should select when the map shows a magnetic
declination of 1° West.
3. When the setting is the way you want, press E to exit the setting screen.
Precautions about bidirectional calibration
• You can use any two opposing directions for bidirectional calibration. You
must, however, make sure that they are 180 degrees opposite each other.
Remember that if you perform the procedure incorrectly, you will get wrong
bearing sensor readings.
• Make sure that you do not move the watch while calibration of either
direction is in progress.
• You should perform bidirectional calibration in an environment that is the
same as that where you plan to be taking direction readings. If you plan to
take direction readings in an open field, for example, calibrate in an open
field.
To perform bidirectional calibration
1. In the Digital Compass Mode, hold down E
for about two seconds until the magnetic
declination angle and magnetic declination
angle direction values start to flash on the
display. This is the setting screen.
2. Press D to display the bidirectional
calibration screen.
• At this time, the north pointer flashes at the
12 o’clock position to indicate that the watch
is ready to calibrate the first direction.
3. Place the watch on a level surface facing any direction you want, and
press C to calibrate the first direction.
•
xxx is shown on the display while calibration is being performed. When
calibration is successful, the display will show
OK and x2x, and the
north pointer flashes at the 6 o’clock position. This means that the watch
is ready for calibration of the second direction.
4. Rotate the watch 180 degrees.

5. Press C again to calibrate the second direction.
•

calibration is successful, the display will show
OK and the Digital Compass
Mode (showing the angle value) screen.
• If
xxx appears and then changes to
ERR
(error) on the calibration
screen, it means that there is something wrong with the sensor. When
ERR
disappears after about one second, try performing the calibration
again. If
ERR
keeps appearing, contact your original dealer or nearest
authorized CASIO distributor to have the watch checked.
To perform northerly calibration
1. In the Digital Compass Mode, hold down E
for about two seconds until the magnetic
declination angle and magnetic declination
angle direction values start to flash on the
display. This is the setting screen.
2. Press D twice to display the northerly
calibration screen.
• At this time,
-N- (north) appears on the
display.

3. Place the watch on a level surface, and position it so that its 12 o’clock
position points north (as measured with another compass).
4. Press C to start the calibration operation.

calibration is successful, the display will show

screen, it means that there is something wrong with the sensor. When

again. If

Using the Digital Compass While Mountain Climbing or
Hiking
This section describes three real-life situations where you could use the
watch’s built-in digital compass.
• To set a map and find your current location
Having an idea of your current location is important when mountain
climbing or hiking. To do this, you need to “set the map”, which means to
align the map so the directions indicated on it are aligned with the actual
directions of your location. Basically what you are doing is aligning north on
the map with north as indicated by the watch.
• To find the bearing to an objective
• To determine the direction angle to an objective on a map and head in that
direction
To set a map and find your current location
1. With the watch on your wrist, position it so the
face is horizontal.
2. In the Timekeeping, Digital Compass,
Barometer/Thermometer, or Altimeter Mode,
press C to take a compass reading.
• The reading will appear on the display after
about two seconds.
3. Rotate the map without moving the watch so
the northerly direction indicated on the map
matches north as indicated by the watch.
• If the watch is configured to indicate
magnetic north, align the map’s magnetic
north with the watch indication. If the watch
has been configured with a declination to
correct to true north, align the map’s true
north with the watch indication.
• This will position the map in accordance
with your current location.
4. Determine your location as you check the
geographic contours around you.

To find the bearing to an objective
1. Take a compass reading and then set the map
so its northerly indication is aligned with north
as indicated by the watch, and determine your
current location.
• See “To set a map and find your current
location” for information about how to
perform the above step.
2. Set the map so the direction you want to travel
on the map is pointed straight in front of you.
3. With the watch on your wrist, position it so the
face is horizontal.
4. In the Timekeeping, Digital Compass,
Barometer/Thermometer, or Altimeter Mode,
press C to take a compass reading.
• The reading will appear on the display after
about two seconds.
5. Still holding the map in front of you, turn your
body until north as indicated by the watch and
the northerly direction on the map are aligned.

• This will position the map relative to your current location, so the bearing to
your objective is straight ahead of you.

in that direction
Note
• The following procedure is possible only with a
watch that has a rotary bezel.
1. Take a compass reading and then set the map
so its northerly indication is aligned with north
as indicated by the watch, and determine your
current location.
• See “To set a map and find your current
location” for information about how to
perform the above step.
2.
As shown in the illustration to the left, change
your position so you (and the 12 o’clock position
of the watch) are pointed in the direction of
objective, while keeping the map aligned with
the readings being produced by the watch.

• If you want to perform both bidirectional and northerly calibration, be sure
to perform bidirectional calibration first, and then perform northerly
calibration. This is necessary because bidirectional calibration cancels any
existing northerly calibration setting.
• The more correctly you perform bidirectional calibration, the better the
accuracy of the bearing sensor readouts. You should perform bidirectional
calibration whenever you change environments where you use the bearing
sensor, and whenever you feel that the bearing sensor is producing
incorrect readings.
To perform magnetic declination correction
1. In the Digital Compass Mode, hold down E
for about two seconds until the magnetic
declination angle and magnetic declination
angle direction values start to flash on the
display. This is the setting screen.
2. Use A (+) and C (–) to change the magnetic
declination angle and magnetic declination
angle direction settings.
• You can select a value within the range of
W 90° to E 90° with these settings.
• The following explains magnetic declination
angle direction settings.
OFF: No magnetic declination correction
performed. The magnetic declination
angle with this setting is 0°.
E: When magnetic north is to the east (east declination)
W: When magnetic north is to the west (west declination)
