CALIBRATION (surface only)
Local magnetic fields can effect display of actual location when reading a digital compass. It may be advantageous to Calibrate
the Compass before its first use after purchase, prior to use in a new region, or if inaccuracies are experienced. Calibration will
be required when the battery is changed.
Upon selecting Calibrate on the Compass Main Menu, a Start screen* is displayed, information includes (Fig. 167) -
> Graphics CAL and ROTATE TO CALIBRATE.
> 360 with ° icon.
*The Start screen will also be displayed after the Battery is changed and Data is either saved or cleared.
• S (< 2 sec) - to activate (start) Calibration.
• S (2 sec) - to step back to the Compass Main Menu.
• Slowly and steadily rotate the unit 360° in either direction while maintaining it in a flat level position (keeping it level is
critical for acurracy), CAL progress will be displayed by a dotted circle forming in the center of the screen (Fig. 168).
Rotation should take about 30 seconds. If not fully rotated in 60 seconds, operation will revert to the Compass Main Menu.
Upon completion, the graphics CAL with PASSED READY or AGAIN FAILED will flash for 3 seconds (Fig. 169A/B), then -
>> If READY, operation will reverts to the Compass OP Main.
>> If FAILED, operation will revert to the Start (CAL ROTATE) screen for repeat.
After 3 attempts, operation will revert to the
Watch or Surface Main and the previous successful Calibration will remain in effect.
