7.1 How compass works

The compass allows you to orient yourself in relation to the magnetic North. There are three different views in the COMPASS mode:

Empty: displays no supplementary information

Heading: displays the numerical degree value of your heading

Time: displays the current time

7.2Getting correct readings

To ensure correct compass readings while in COMPASS mode, you need to calibrate the compass correctly when prompted, set the correct declination value, keep the device level, and keep away from metal (for example, jewelry) and magnetic fields (for example, power lines).

To calibrate the compass you need to keep the device level (do not tilt it in any directions), slowly rotate the device clockwise (around 15 seconds per round) until the compass is activated. The compass will switch itself to power saving mode after a minute. You can reactivate it by pressing [Start Stop].

NOTE: If the compass is not showing consistent values, you need to calibrate it. Keep the device level and rotate it slowly clockwise until the north indicator is stable again. This can take up to 3 rotations.
