Mark or MOB
This is a dual function key that either stores your present position,
date and time at the next available waypoint location in the Waypoint
Bank or when pressed continuously for 3 seconds, calculates a MOB
range and bearing to a saved spot (See MOB section on page 84). A
window pops up on the screen to confirm your key depression, and to
tell you where the Mark position is being stored. You can go into the
WPT menu and edit the coordinates or description later. This key
function is disabled for 2 seconds after each depression.
The cross-hair (
⊕
) symbol to the left of the date in the Waypoint
Bank indicates that the Mark or Event key created this waypoint.
Note that you can also select the cross-hair (
⊕
) symbol from the vari-
ous symbols for other waypoints when editing waypoints.
The CDU is also capable of performing this function from a remote
contact closure input via the 8-pin AUX Cable “MOB/Event” wire.
Refer to the
Appendix F (Installation Section) of this manual for in-
terface instructions. Contact closure on the two input pins for 1 sec-
ond causes a Mark position to be generated. Contact closure on the
two input pins for 3 seconds causes a Man Over Board condition to
be generated.
Note: The marker function stores the position of the antenna
location. Keep this in mind if you are trying to pinpoint
items such as buoys, crab pots, etc. For some special
applications such as these, you may need to locate
the antenna at the point on the boat or ship where you
need to make this exact measurement.
