Digital Compass
In the Digital Compass Mode, a built-in bearing sensor detects magnetic north at regular intervals and
indicates one of 16 directions on the display.

Digital Compass Readings
• When you press

to start digital compass measurement,
COMP
will appear on the display initially to
indicate that a digital compass operation is in progress.
• About two seconds after you start a digital compass measurement operation, letters on the display will
indicate the direction that the 12 o’clock position of the watch is pointing. Four pointers that indicate
magnetic north, south, east, and west also will appear.
• After the fi
each second for up to 20 seconds. After that, measurement will stop automatically.
• The direction indicator and angle value will show
- - -
to indicate that digital compass readings are
complete.
• The auto light switch is disabled during the 20 seconds that digital compass readings are being taken.
• The following table shows the meanings of each of the direction abbreviations that appear on the
display.

example, the actual direction can be anywhere from 304 to 326 degrees.

• Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in
large measurement error.
• You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
• Any ongoing direction measurement operation is paused temporarily while the watch is performing an
alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned
on (by pressing
L
). The measurement operation resumes for its remaining duration after the operation
that caused it to pause is fi
• See “Digital Compass Precautions” for important information about taking direction readings.
Calibrating the Bearing Sensor
You should calibrate the bearing sensor whenever you feel that the direction readings being produced by
the watch are off. There are three different calibration methods available: magnetic declination correction,
bidirectional calibration, and northerly calibration.
•
Magnetic Declination Correction
With magnetic declination correction, you input a magnetic declination angle (difference between
magnetic north and true north), which allows the watch to indicate true north. You can perform this
procedure when the magnetic declination angle is indicated on the map you are using. Note that you can
input the declination angle in whole degree units only, so you may need to round off the value specifi ed
on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6°
input 8°, for 7.5° you can input 7° or 8°.
•
Bidirectional Calibration and Northerly Calibration
Bidirectional calibration and northerly calibration calibrate the accuracy of the bearing sensor in relation
to magnetic north. 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).
Important!
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.
• 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 fi

To perform northerly calibration
Important!
If you want to perform both northerly and bidirectional calibration, perform bidirectional calibration fi
and then perform northerly calibration. This is necessary because bidirectional calibration cancels any
existing northerly calibration setting.
