G-PILOT 3380 System Installation Manual NAVMAN 27
Note
To exit the calibration at any time, press ESC.
If the boat is not turned as prompted or the compass is not working then calibration can not be com-
pleted, the G-PILOT 3380 system displays an error. Press ESC, fix the problem and repeat the calibration.
Local disturbances in magnetic field may affect the compass. Calibration must be preformed away from
large metal structures such as marinas, large ships etc.; this is the responsibility of the user.
Ensure that both sources are referencing the same north (true or magnetic). If your magnetic compass
has not been calibrated then you can use another source for heading. If using vessel’s compass then
ensure that the deviation tables are applied to check the autoG-PILOT’s compass.
To calibrate the Compass unit go to Compass in the Setup > Calibrate menu. Follow the on-screen
instructions presented by the calibration wizard (See G-PILOT 3380 Operation Manual).
5-1 Calibrating the compass
5 Sea trials
Perform the sea trials:
After performing the dockside setup (see
section 4).
To check the operation of the
G-PILOT 3380 system.
For the sea trials, sail in an open area where there
are no other craft or obstructions. The sea should
be calm, the wind speed as low as possible and
there should be no currents.
This aligns the G-PILOT 3380 system compass to display the correct heading.
The compass can be aligned either to a reference compass or to a GPS connected to the G-PILOT 3380
system. Ensure there is no cross-wind or current.
To align the Compass unit go to Align heading in the Setup > Calibrate menu. Follow the on-screen
instructions presented by the calibration wizard (See G-PILOT 3380 Operation Manual).
5-2-2 Aligning the Rudder (Centre rudder)
This sets the rudder setting to sail a straight course. Ensure there is no cross wind or current.
To align the rudder go to Centre rudder in the Setup > Calibrate menu. Follow the on-screen
instructions presented by the calibration wizard (See G-PILOT 3380 Operation Manual).
5-2 Aligning the compass and the rudder
5-2-1 Aligning the compass (Align heading)
The compass or rudder can be aligned separately.
