•Y ou can turn off (OFF ) magnetic declination correction (which effectiv ely
makes the magnetic declination angle: 0° ) by pressing A and C at the
same time.
•The illustration, for e xample, shows the value y ou should input and the
direction setting you should select when the map sho ws a magnetic
declination of 1° West.
3. When the setting is the wa y you want, press E to e xit the setting screen.
Precautions about bidirectional calibration
•Y ou can use any two opposing directions f or bidirectional calibration. Y ou
must, howe ver , make sure that they are 180 degrees opposite each other .
Remember that if you perf orm the procedure incorrectly , you will get wrong
bearing sensor readings.
•Make sure that y ou do not move the w atch while calibration of either
direction is in progress.
•Y ou should perform bidirectional calibration in an en vironment 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, f or example, calibr ate 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 displa y the bidirectional
calibration screen.
•At this time, the north pointer flashes at the
12 o’ clock position to indicate that the w atch
is ready to calibrate the first direction.
3. Place the watch on a le vel surf ace facing an y direction you want, and
press C to calibrate the first direction.
•xxx is shown on the display while calibr ation is being performed. When
calibration is successful, the display will sho w OK and x2x , and the
nor th pointer flashes at the 6 o’ clock position. This means that the w atch
is ready for calibration of the second direction.
4. Rotate the watch 180 degrees.

5. Press C again to calibrate the second direction.
•xxx is shown on the displa y while calibration is being performed. When
calibration is successful, the displa y will show OK and the Digital Compass
Mode (showing the angle v alue) 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 hav e the watch check ed.
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 norther ly
calibration screen.
•At this time, -N- (nor th) appears on the
display .

3. Place the watch on a level surf ace, and position it so that its 12 o’ clock
position points nor th (as measured with another compass).
4. Press C to star t the calibration operation.
• --- is shown on the displa y while calibration is being performed. When
calibration is successful, the display will sho w OK and the Digital Compass
Mode (with 0 ° shown as the angle v alue).
•If --- 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 hav e the watch check ed.
Using the Digital Compass While Mountain Climbing or
Hiking
This section describes three real-life situations where y ou could use the
watch’s built-in digital compass.
•T o set a map and find your current location
Having an idea of your current location is important when mountain
climbing or hiking. T o 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 nor th as indicated by the watch.
•T o find the bear ing to an objective
•T o deter mine 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 nor therly 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 w atch
has been configured with a declination to
correct to true nor th, align the map’s true
north with the watch indication.
•This will position the map in accordance
with your current location.
4. Deter mine your location as you chec k the
geographic contours around you.

To find the bearing to an objective
1. T ake a compass reading and then set the map
so its nor therly indication is aligned with nor th
as indicated by the watch, and determine your
current location.
•See “T o set a map and find your current
location” for inf ormation about how to
perf or m the above step .
2. Set the map so the direction you want to trav el
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 nor th as indicated by the watch and
the nor therly direction on the map are aligned.

Note
•The follo wing procedure is possible only with a
watch that has a rotary bezel.
1. T ake a compass reading and then set the map
so its nor therly indication is aligned with nor th
as indicated by the watch, and determine your
current location.
•See “T o set a map and find your current
location” for inf ormation about how to
perf or m the above step .
2.
As shown in the illustr ation to the left, change
your position so y ou (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 b y the watch.

Important!
•If you want to perf or m both bidirectional and nor therly calibration, be sure
to perform bidirectional calibration first, and then perf or m nor ther ly
calibration. This is necessary because bidirectional calibration cancels any
e xisting nor ther ly calibration setting.
•The more correctly you perf orm bidirectional calibration, the better the
accuracy of the bearing sensor readouts. Y ou should perf or m bidirectional
calibration whene ver you change en vironments where you use the bearing
sensor , and whenev er you f eel 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.
•Y ou can select a value within the range of
W 90° to E 90 ° with these settings.
•The following e xplains 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)
