Calibrating The Compass - Suunto M9 Quick Manual

CALIBRATING THE COMPASS

You should calibrate the compass if it does not seem
to function properly, 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 it is advisable to
calibrate the compass if your Suunto M9 has been
exposed to these fields.
Note: Calibrate the compass before using it for the
first time, and before you leave for an extended out-
door activity.
To calibrate the compass, select CALIBRATE in the
Compass menu.
Hold the unit horizontally and rotate it slowly around
the vertical axis until the down counter reaches zero.
Turn the unit vertically and rotate it slowly around
the vertical axis until the down counter reaches zero.
After this the unit calculates a while after which the
compass is calibrated and Suunto M9 displays the
message 'COMPLETE'. Press Enter to return to the
main display.
