Taking Direction Readings
You can use the Digital Compass Mode to determine the direction of north, and to check your bearing to a
destination.
• For information about what you can do to improve digital compass reading accuracy, see “Calibrating
the Bearing Sensor” (page E-22) and “Digital Compass Precautions” (page E-27).
To take a direction reading
1. Make sure the watch is in the Timekeeping Mode or any one of the sensor modes.

Important!
• If the digital display contents start to fl ash after you perform a reading operation, it means that abnormal
magnetism has been detected. Move away from any potential source of strong magnetism and try
taking a reading again. If the problem occurs when you try again, continue to keep away from the
source of strong magnetism, perform bidirectional calibration, and then try taking a reading again. For
more information, refer to “To perform bidirectional calibration” (page E-23) and “Location” (page E-27).
Digital Compass Readings
• When you press

to start digital compass reading operation,
COMP
will initially appear on the
display to indicate that a digital compass operation is in progress.
• After the fi
each second for up to 60 seconds. After that, the reading operation 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 60 seconds that digital compass readings are being taken.
• The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is
horizontal (in relation to the horizon). If the indicated direction is northwest (
NW
) and 315 degrees, for
example, the actual direction can be anywhere from 304 to 326 degrees.
• Note that taking a direction reading while the watch is not horizontal (in relation to the horizon) can
result in large direction reading error.
•
You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
• Any ongoing direction reading 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 direction reading operation resumes for its remaining duration after the operation
that caused it to pause is fi
• See “Digital Compass Precautions” (page E-27) 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. You can use any one of two different bearing sensor calibration methods: bidirectional
calibration or magnetic declination correction.
•
Bidirectional Calibration
Bidirectional calibration calibrates 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.
Important!
• To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before
using it. The watch may produce incorrect direction readings if you do not perform bidirectional
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
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°.
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.
E-23
• 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
