Important!
•
If the second hand does not point exactly at 12 o’clock after you perform step 3 above, perform the
operation under “Hand Home Position Adjustment” (page E-39) to adjust it.
•
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-57) and “Location” (page
E-60).
Digital Compass Readings
•
After the fi
rst reading is obtained, the watch will continue to take digital compass readings automatically
each second for up to 60 seconds. After that, the reading operation will stop automatically.
•
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 ±10 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 305 to 325 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 nished.
