2
Set the display to view heading data from the antenna.
3
Disconnect the antenna from the NMEA 2000 network or turn
off the power to the NMEA 2000 network.
4
Wait while the boat becomes level and stationary.
5
Turn on power to the antenna, and wait until the heading data
appears on the display .
6
Within three minutes, complete two full, slow, tight circles ,
taking care to keep the boat as steady and level as possible.
Heading data disappears to indicate that the antenna has
detected the start of the procedure .
You may receive an error message that the heading was lost.
You can ignore this message.
7
Bring the boat to a complete stop , and remain stationary
for two minutes.
After two minutes, the heading data reappears with a fixed
value of 123 degrees to indicate heading will be disabled
on the next power cycle.
NOTE:
If the magnetic heading is displayed, the fixed value
is 123 degrees. If the true heading is displayed, the fixed
value may deviate because of corrections from magnetic
variation.
8
Disconnect the antenna from the NMEA 2000 network or turn
off the power to the NMEA 2000 network.
9
Turn on power to the antenna, and verify that heading has
been disabled .
