CoMpass sCreen
There is only one screen display available in the CoMpass mode.
The display shows the tiMe oF day in the top line. The Current
heading in Quarter Cardinal points is shown as a rotating
scale across the center line and the bottom line displays the Current
heading in degrees.
CaliBrating the CoMpass
The CoMpass must be calibrated on a regular basis. The compass
should be calibrated any time it does not seem to be working properly.
We recommend calibrating the compass prior to any activity where
optimal accuracy is desired, such as a long back country trip.
1. Start in CoMpass mode.
2. press & hold the s5 key to enter the calibration sequence.
3. Cal will appear in the center line of the display.
4. Rotate the watch clockwise for two complete rotations of
approximately 15-seconds per rotation.
5. To exit the calibration sequence at this point QuiCK press the s1
key. Or advance to setting the magnetic declination using a QuiCK
press of the s5 key.
note: For the optimum accuracy, the compass must be held
completely level during the calibration process. We recommend
placing the unit on top of a drinking glass while performing
the calibration as this will make it easier to keep the compass
level.
The ATF8 / Alterra / Altiforce is equipped with a highly accurate digital magnetic compass with reading
in one degree increments. The compass can be adjusted to compensate for the magnetic declination
corresponding to the area where the compass is being used.
