4.1 Entering Waypoints
In navigation terminology a waypoint is a
particular location on a voyage whether it be
a starting, intermediate or destination
waypoint.
The DD-80 can store 999 waypoints, num-
bered from 001–999. Waypoints can be reg-
istered four ways:
• by cursor
• by MOB position or event position
• at own ship's position, and
• through the waypoint list.
Waypoints are mutually entered when the
navigators are sharing data.
Entering waypoints by the cursor
1) Press the [WPT RTE] key. The Waypoint/
Route menu appears.

A window similar to the one shown in Fig-
ure 4-3 appears. The waypoint's position
and date and time registered appear on the
first and second lines. Waypoints are au-
tomatically given the youngest empty
waypoint number and this number appears
on the third line. You may, however, as-
sign a different number. If the waypoint
shares the same position with a mark, the
mark's position and date and time entered
are registered as waypoint data.
If the waypoint memory is full, the
waypoint number line in the window is
blank. In this case waypoints cannot be
entered unless a waypoint is written over
or erased.
To assign waypoint number, go to step 5.
If you do not want to change the waypoint
number, go to step 6 to select mark shape
and enter comment.
