3.4.2. Calibrating the compass
To ensure that the compass works properly, you need to calibrate it.
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.
• If your Suunto X10 has been exposed to strong electromagnetic fields, such as
electric lines, loudspeakers and magnets, which can affect the compass operation.
• Before you use it for the first time
• Before you leave for an extended outdoor activity.
To calibrate the compass:
1.In the Set menu, scroll to Calibrate and press ENTER.
The message ‘
ROTATE 360° HORIZONTAL ’, a set of arrows
and a 30 second timer are displayed.
