3. Nav Repeater Mode
If you have connected your Sailcomp 103AC to a NMEA 0183 Loran or GPS, you can
access navigational information by pressing the
nav button
.
As long as both the Sailcomp 103AC and the
loran/GPS are powered up, each time you push the
nav button
, the display will show loran/GPS infor-
mation. The Nav Repeater Mode provides steering
information only, so if your loran or GPS is giving
position information, you will not get any steering
information on your Sailcomp 103AC display. In
this case, when you push the
nav button
, the display will read "- - -" to remind you
that you have not entered any waypoints into your loran or GPS. Also, if for any rea-
son your loran or GPS is switched off at its box, the Sailcomp's Nav Display will revert
to "- - -" to warn you that it is not receiving any information from the loran or GPS.
When you instruct your loran or GPS to steer you to a waypoint, the Nav Display will
be activated. Every 2 seconds the repeater will alternate between displaying "
Bearing
to Waypoint"
and
"Distance to Waypoint
"*.
As you progress, if you get any cross track error, the upper part of the Sailcomp dis-
play will show you cross track error to port or starboard with segments in increments
of
.05 nautical miles
while Distance to Waypoint is displayed. When there are no seg-
ments on the upper display, this means that you are on the rhumb line to your way-
point.
Once you are in the Nav Repeater Mode, pushing any other button will exit the Nav
Repeater Mode and put you into the pressed button's Mode.
