4.3.3. Compass settings
You can define the compass settings ( calibration, declination and time-out) when in
COMPASS mode:
Calibration
Because of changes in the surrounding magnetic field, the Suunto Vyper
AIR
electronic
compass occasionally needs to be re-calibrated. During the calibration process, the
compass adjusts itself to the surrounding magnetic field and to tilting. As a basic rule, you
should calibrate the compass whenever it doesn’t seem to operate properly, or after
replacing the dive computer's battery.
First the compass is level calibrated and after a successful level calibration, the compass
is tilt calibrated. The tilt calibration compensates for tilting the compass in any direction in
angles of up to 45°.
Strong electromagnetic fields, such as power lines, stereo speakers, and magnets can
affect the compass calibration. It is therefore advisable to calibrate the compass if your
Suunto Vyper
AIR
has been exposed to these fields.
NOTE When traveling overseas, it is recommended that you recalibrate the
compass at the new location before using it.
NOTE Remember to hold the Suunto Vyper
AIR
level during the level
calibration process. A deviation of ± 5° is allowed in any direction
from the horizontal plane during level calibration.
To calibrate the compass:
