Keep turning until the display reads “Compensation OK”; usually, it takes a bit more that
one full turn, but sometimes it can take 2 or 3 turns.
• If after several turns, the display does not say “Compensation OK”, or if it says
“Compensation Failed”, check all wiring, and/or relocate the compass, and begin the
procedure over.
• If you continue to encounter difficulties, please contact your ComNav Dealer for
assistance.

45° Compass
If you are not already in the Compass Configuration menu, start it as by selecting “Compass
Setup” & press the Fn button.
1) Move the highlight to “Digital Compass”, and set the parameter to “Fixed”, and press the
Fn button.
2) The rest of the compensation procedure is same as the step 4) to step 7) in above for the
compensation of Fluxgate Compasses.
Tri-Axis Rate Gyro Compass
Note you will only be able to calibrate the gyro compass when the compass is connected to
NAV1 port, and you have followed the wiring in Figure 43 on page 67.
If you are not already in the Compass Configuration menu, start it as by selecting “Compass
Setup” & press the Fn button from the Dockside Setup Menu (see the Dockside Setup Menu
in Figure 66 on page 90).
1) Move the highlight to “NAV1 Port”, and set the parameter to “ SSRC1 ”, and press the Fn
button.
2) The rest of the compensation procedure is same as the step 4) to step 7) in above for the
compensation of Fluxgate Compasses.
Other NMEA Compasses
Many NMEA compasses will not require compensation such as the ComNav Vector G1/G2/G2B
GPS Compass. In all cases, you should refer to the instructions that came with your compass to
determine whether compensation is needed and how to do it.
