position. When the MOB condition is canceled via a MOB screen
softkey, the NMEA sentences will automatically revert to the
active route information.
Don’t forget to cancel the MOB so your
interfaced equipment will read the correct data.
¾ The MOB function key and remote MOB input are disabled from
subsequent activation, until the
MOB Cancel softkey is selected.
¾ Other functions such as Position and Navigate can still be ac-
cessed; however, the screen will revert to the MOB Plot screen
after 30 seconds. Bearing and distance information in these other
screens relate to the MOB position, not the next waypoint in the
active route, until MOB is canceled.
To cancel a MOB condition, make sure you are in the MOB Plot
screen. Press the
EDIT function key, then select the Cancel MOB
softkey.
The MX 500 is also capable of performing the MOB function from a
remote contact closure. If the contact closure is made for 1 second,
the input is registered as a Mark Position. If the contact closure is
made for 3 seconds, the input is registered as a MOB Position. Refer
to the
Appendix F of this manual for interface instructions.
GOTO
This function key allows you to quickly create a route from your
present position to waypoint or a route. This single waypoint route
can use an existing waypoint from the Waypoint Bank, or you can
quickly create one by either defining the appropriate coordinates or
specifying a range and bearing.
Be careful when you use this selection, as it will erase your current
active route when it creates the new one. Read through the
ROUTE
and PLOT sections of this manual to find other ways to use this key
within an active route.
POWER ON/OFF & LIGHT
This triple function key turns the unit on and off. When depressed
while the unit is on, you will be prompted to select a
YES or NO
softkey to confirm your action. This is known as a software power
off .
