1.7 Entering the MOB Mark, Setting MOB as
Destination
The MOB mark functions to mark man
overboard position. You can inscribe the
mark from any mode except nav data,
when playing back data or conducting
any test. Note that this function requires
position data.
Note: The function of the SAVE/MOB
key depends on the setting of SAVE
MOB KEY FUNCTION in the GENERAL
SETUP menu. The description below
shows the procedure using the default
setting. For further details, see Save
MOB Key Function on page 7-2.
1. Press and hold down the SAVE/MOB key for about three seconds when someone falls
overboard. The display shows the waypoint number being saved (youngest empty
waypoint number, 001-999) followed by the MOB confirmation window.

2. Push the ENTER knob to select the MOB position as the destination, or press the
CLEAR key to only mark current ship’s position as a waypoint. If you select the MOB
position as destination;
• A full-screen radar, plotter or overlay appears depending on the display in use. (If the
MOB key function is “MOB Without Confirmation” the range is automatically set to
0.5 nm.) Further, the waypoint marker appears on the radar display.
• The MOB mark “MOB” appears at the MOB position and a blue line runs between it
and current position. This line shows the shortest course to the MOB position.
• Range and bearing to the MOB position are shown in the MOB data box.
To erase an MOB mark from the plotter display, you must first erase its corresponding
waypoint. Place the cursor on the MOB mark, then press the CLEAR key followed by
pushing the ENTER knob to erase the waypoint. Then, repeat to erase the MOB mark.
