Entering Waypoints

In navigation terminology, a waypoint is a
particular 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
destination, 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
position, 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 position.
This new waypoint will automatically be saved
in the waypoint list under the next consecutive
waypoint number. For FISHING 2 mode, the
waypoint data (comment, shape etc.) can be
changed at this time. See the next page for
how to change the mark. Note that press the
SAVE soft key after a mark is changed.
Entering waypoints at MOB position
The MOB mark functions to mark man
overboard position. For FISHING2 mode, this
mark can be edited as similarly with the
procedure on the next page.
1. Press the [SAVE/MOB] key down several
seconds to display the following message.
MAN OVER BOARD!
GO TO (MOB)?
YES ... "ENTER" key
NO ... "CLEAR" key

Until this window displaying, "SAVING
WAYPOINT XXX" appears for the normal
waypoint.
2. Press the [ENTER] key to select MOB
position as destination, or the [CLEAR] key
to only mark MOB position.
3. To show range and bearing to the MOB
position, press the NAV POS soft key.

MOB concept
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 followed by
the [ENTER] key to erase the waypoint. (A
flashing diamond appears over the waypoint
when it has been correctly selected.) Repeat to
erase the MOB mark.
