6.1.1 Calibrating
compass
The device needs to be carefully calibrated during first time use and when the
battery is replaced. The device will prompt you when calibration is needed.
To calibrate the
compass:
1. Keep the device level, do not tilt it in any directions.
2. Slowly rotate the device clockwise (around 15 seconds per round) until
the
compass is activated.
NOTE: If you notice deviations in the
compass, you can recalibrate it by keeping
it level and rotating it slowly clockwise until the north indicator shows a stable
value.

 | Compass |  | Compasses are sensitive, absolutely crucial instruments to precision navigation. The earth's magnetic field, inclination, and your longitude and latitude all influence the horizontal plane of a compass needle. As a result, compasses are balanced for different geographical zones. Suunto Compasses overcome this limitation to traditional compasses by using a simple 'Two Zone System'. With a Suunto Compass, the only 'balancing zones' are the northern and southern hemispheres. In addition to this innovation, certain Suunto Compasses come equipped with useful features like luminous needles and marks, centimeter/inch scales, magnifying glasses, clinometers, sighting notches, and more. | |  |
