Calibrating the Bearing Sensor
Whenever you suspect that direction readings produced by the watch are
wrong, you should calibrate it. You can use either one of two calibration
procedures: bidirectional calibration or northerly calibration .
Use bidirectional calibration when you want to take readings within an area
exposed to magnetic force. This type of calibration should be used if the
watch becomes magnetized for any reason.
With northerly calibration, you "teach" the watch which way is north (which
you have to determine with another compass or some other means). You
could use this calibration procedure, for example, to set the watch to indicate
true north instead of magnetic north.
Important!
• 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
previously set 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.
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. Press A to enter the Digital Compass Mode.
2. Hold down E until
display, which indicates the setting screen.
• At this time, the magnetic 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 A to calibrate the first direction.
•

When calibration of is successful, the display will show
and the magnetic 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 A again to calibrate the second direction.
•

calibration is successful, the display will show

again. If

authorized CASIO distributor to have the watch checked.
To perform northerly calibration
1. While in the Digital Compass Mode, hold
down E until
which indicates the setting screen.
2. Press D to start the northerly calibration
procedure.
• At this time,

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 A to start the calibration operation.

Barometer and Thermometer Precautions
• The pressure sensor built into this watch measures changes in air
pressure, which you can then apply to your own weather predictions. It is
not intended for use as a precision instrument in official weather prediction
or reporting applications.
• Sudden temperature changes can affect pressure sensor readings.
• Temperature measurements are affected by your body temperature (while
you are wearing the watch), direct sunlight, and moisture. To achieve a
more accurate temperature measurement, remove the watch from your
wrist, place it in a well ventilated location out of direct sunlight, and wipe all
moisture from the case. It takes approximately 20 to 30 minutes for the
case of the watch to reach the actual surrounding temperature.
Pressure Sensor and Temperature Sensor Calibration
The pressure sensor and temperature sensor built into the watch are
calibrated at the factory and normally require no further adjustment. If you
notice serious errors in the temperature readings produced by the watch, you
can calibrate the sensor to correct the errors.
Important!
• Incorrectly calibrating the barometric pressure sensor can result in incorrect
readings. Before performing the calibration procedure, compare the
readings produced by the watch with those of another reliable and accurate
barometer.
• Incorrectly calibrating the temperature sensor can result in incorrect
readings. Carefully read the following before doing anything.
Compare the readings produced by the watch with those of another reliable
and accurate thermometer.
If adjustment is required, remove the watch from your wrist and wait for 20
or 30 minutes to give the temperature of the watch time to stabilize.
To calibrate the pressure sensor and the temperature sensor
1. Press B to enter the Barometer/
Thermometer Mode.
2. Hold down E until
upper display area.
3. Release E, and wait for four or five more
seconds until either
reference temperature value (if set) start to
flash. This is the setting screen.
• If you want to calibrate the barometric
pressure sensor, press D to move the
flashing to the middle display area. This is
the pressure sensor calibration screen.
• At this time,
pressure value should be flashing on the
display.
4. Use the C (+) and A (–) buttons to set the
calibration value in the units shown below.

5. Press E to return to the Barometer/Thermometer Mode screen.
To select the temperature, barometric pressure, and altitude units
1. Enter the Timekeeping Mode.
2. Hold down E until the city code starts to
flash, which indicates the setting screen.
3. Use D to select the setting screen for the unit
you want to change.
• See step 2 under "To set the time and date"
for information about how to scroll through
setting screens.
4. Press C to change the unit setting.
• Each press of C changes the selected unit
setting as shown below.
