Operator's Manual
There are four basic NAV screens. NAV4 only provides data if appro-
priate sensors (e.g. wind speed/direction logs, NMEA compass, etc.)
are interfaced and activated on the COD. TheNAVfunctions are highly
interactive with the R1El screen, and a number of CFG menu selec-
tions.
The RTEl screen provides the active route for the NAV screens. It
also maintains a waypoint pass log for you. One other important fea-
ture in the R1El screen that you need to be aware ofis that the up and
down arrow softkeys control which waypoints are skipped (down ar-
row) andwhich are restored (up arrow) for your current route. The ETA
information is configured in the RTE I screen. Refer to the Route sec-
tion of the manual for a full description.
The following CFG menus directly impact the NAV functions:
~
COG SOG - sets the filtering time for the displayed values.
~ Datum - sets the reference datum for your present position and
waypoints in the active route.
