Repeated key presses will result in cycling through the character options repeatedly.
When the operator stops pressing keys for longer than the preset timeout, the last
value is retained and the cursor moves to the next location in the field. Pressing a
different key forces acceptance of the last character for the field and moves the cur-
sor along.

FNC-ENT Own Ship display

(NAV Key will also bring up this screen if already showing the Closest
Vessel display.)

The AIS interface consists of the following display screens each of which is ac-
cessed using the defined key sequence.

MKD will default to this screen after 30 seconds when the unit is idle.
This display shows closest three (3) targets by MMSI number or ship name, the
range in nautical miles, and bearing of each target.  Using the up (↑) or down (↓) ar-

row keys you may scroll through every target that is detected.

I = Internal Time:

 for timing, after losing internal and slot timing. It will
