6.3 CalIbRaTIng THe CoMPass
a compass calibration should be done whenever the Wristop computer has been subject to close proximity of magnetic sources,
extreme cold weather, every time the battery is replaced or it is suspected that other environmental conditions have effected the
compass readings.
note: We also recommend calibrating the compass before using the compass the first time, as well as when heading outdoors to use
the compass.
To begin the calibration:
. press the [select] button twice when in the main compass mode. field  displays the text “cmp”. field 3 displays the text “cal”
(fig. 56).
2. PRESS the [Select] button and hold for 2 seconds. Located in Field 2, the text “PUSH” will begin to flash (Fig. 57).
3. press the [-] button to start calibration .
4. In field , 360° appears and the outer circumference displays all segments lit (fig. 58). When this occurs, hold the Wristop
computer level and start to slowly turn the device around a full circle in a level position. the direction of turning does not matter.
The lit segments will be turned off as the turning proceeds. When the first full circle is completed, the instrument will inform the user
within one minute of whether the calibration was successfull, displaying the text “done” in field  (fig. 59), or if the process needs
to be repeated, displaying “pusH” and “-” in field .
note: the user may need to perform the rotating of the compass more than twice around for the calibration to be completed.
