Setting the Ship’s Heading
Caution! This is only used if the compass malfunctions; changes will be
overwritten when the compass is functional again.
If the ship uses a Step-by-Step compass, or if the compass becomes inactive or
unconnected (for example, during system installation), you need to set the ship’s heading
manually.
To set the heading:
1. Put the
ANTENNA
into Stand-by Mode (for instructions, see
on page 8-6).
2. From the
Operation Screen
, open the
Commands
menu and select
Set Compass
.
The
Ship Heading
dialog box appears.

3. Do one of the following:
For an incremental compass (Step-by-Step, Synchro 36:1, Synchro 60:1, Synchro
90:1, Synchro 180:1, Synchro 360:1), enter a start value in the
Enter Current
Ship Heading
field.
For an absolute compass (NMEA-0183, Synchro 1:1), a default compass value may
be entered (for example, during
ANTENNA
commissioning). This value will be used
until a valid compass update is received.
4. Click
OK (Enter)
. The ship’s heading is updated in the
Compass
field of the
Ship
Coordinates
window.
