Calibrating The Compass - Suunto G9 Instruction Manual

3.4.2. Calibrating the Compass

You should calibrate the compass if it does not seem to work well, for example, when
it displays the wrong compass heading or the heading changes too slowly. Strong
electromagnetic fields, such as electric lines, loudspeakers and magnets, can affect
the compass operation. Therefore you should calibrate the compass if your Suunto G9
has been exposed to these fields.
NOTE: Calibrate the compass before using it for the first time, and before you leave
for an extended outdoor activity.
NOTE: Remember to hold Suunto G9 level during the calibration.
2. Time: The current time.
3. Bearing: If one of the objects of the field has been
activated on the Course mode's main display, this row
shows the bearing to the object.
