Calibrating the compass
For the most accurate compass reading, calibrate the
compass whenever traveling a significant distance to a
new dive destination. If you dive in the same area, it is
not necessary to calibrate the compass.
Follow these steps to calibrate the compass:
1. Put the QuantumX into compass mode.
2. Press and hold the B button until the message
"ROTATE SLOWLY" and an empty circle appears
at the top of the screen.
3. Keeping the computer level, slowly rotate until the circle fills completely and
the message "ROTATE OK" appears.
4. Press and hold the B button to exit the calibration mode.
