Operation Manual

Robertson AP300X Autopilot
48 22081814H
2.13 Waypoints
A waypoint is any position that you want to navigate to. It can be a
buoy, the entrance to an inlet, a favorite wreck location, or an
intermediate turning point 300 miles out in the ocean.
Three different types of waypoints are available in the AP300DLX
navigator:
Stored waypoints (98 are available), Temporary Waypoint (1 is
available), and Man Over Board (MOB) waypoint.
To have the AP300DLX navigate to a waypoint, you must first store it
into the memory, then you select the waypoint to go to. You can assign
up to an 8 character name to each stored waypoint, or allow the
AP300DLX to assign a number that represents the waypoint position in
the waypoint list. You will find it much easier to remember what a
waypoint location represents if you assign a descriptive name to each.
Waypoints are stored in Latitude and Longitude only! The Lat/Lon
system is universal to both GPS and Loran systems, and in addition,
virtually all electronic video chart/plotter systems are based on the
Lat/Lon system.
Note ! Waypoints are stored in Degrees, Minutes and Hundreds of minutes, (not
seconds!) and position data is presented in the same manner.
Storing waypoints
When you enter the ADD screen, the AP300DLX has automatically
selected the first available waypoint on the waypoint list, and input the
ship's current position as the waypoint position. You need to assign a
name (up to 8 characters) and adjust the Latitude and Longitude to the
values for the waypoint.
You will use the course dial to change the values or the characters, and
use the PORT and STBD push buttons to change the flashing cursor
position on the screen. Pressing the key advances the cursor to the next
line.
The list of characters is shown below:
0123456789_abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
