6. WAYPOINTS
6.1 Entering Waypoints
In navigation terminology, a waypoint is a par-
ticular location on a voyage whether it be a
starting, intermediate or destination point. A
waypoint is the simplest piece of information
your equipment requires to get you to a des-
tination, in the shortest distance possible.
This unit has 835 waypoints (including quick
waypoints) into which you can enter position
information. There are five methods by which
you can enter a waypoint: at own ship’s po-
sition, at MOB position, by cursor, by range
and bearing, and through the waypoint list
(manual input of latitude and longitude).
Entering waypoints at own ship’s
position
You can save your current position as a
waypoint. Press the [SAVE/MOB] key with a
touch-and-release action to store your posi-
tion. This new waypoint will automatically be
saved in the waypoint list under the next con-
secutive waypoint number.
Entering waypoints at MOB position
The MOB mark functions to mark man over-
board position.
1. Press the [SAVE/MOB] key several sec-
onds to display the following message.

2. Press the [ENTER] key to select MOB
position as destination, or the [CLEAR]
key to only mark MOB position.

position, press the soft key NAV L/L fol-
lowed by the soft key NAV WPT.

To erase a MOB mark, you must erase both
the waypoint it is registered under and the
MOB mark itself. Place the cursor on the
MOB mark and press the [CLEAR] key fol-
lowed by the [ENTER] key to erase the
waypoint. (A flashing diamond appears over
the waypoint when it has been correctly se-
lected.) Repeat to erase the MOB mark.
