Operation Manual

Compass calibration
Do not attempt to start calibration when the IS20
and an autopilot
are part of the same system unless
the autopilot is in STBY mode!
Before the compass calibration is started, make sure that
there is enough open water around the vessel to make a
full turn.
The calibration should be done in calm sea conditions and
with minimal wind to obtain good results. Use about 60-
90 seconds to make a full circle.
1. Begin turning the boat to port or starboard
2. Refer to the illustration below to start the automatic
compass calibration
A failing calibration could occur if:
− The compass is located too close to a local
magnetic object
− The autopilot is not set to STBY mode
If an autopilot is part of the same SimNet system, the
autopilot should be used to calibrate the compass!
