Auxiliary
The MOB position, date and time are stored in the next vacant
waypoint memory of the Waypoint Bank for future reference (e.g. log
book entries). An MOB symbol is used to denote an MOB waypoint.
Note: The range and bearing in the PLOT, NAV,
NMEA 0183 sentences (i.e. BWC and BWR) and the printer output
are changed to reflect the current crisis situation by also indicating
the bearing and range back to the MOB position (until the MOB is
canceled). This way, other interfaced equipment can also help guide
you back to the MOB position. When the MOB condition is can-
celed, the NMEA sentences will automatically revert to the active
route information. Don't forget to cancel the MOB so your inter-
faced equipment will read the correct data.
The MOB function key and remote MOB input are disabled from
subsequent activation until Cancel MOB is selected.
Other functions such as Position and Navigate can still be accessed;
however, the screen will revert to the MOB Plot screen after 30 sec-
onds.
Version 3.0
and MOB screens all reflect your bearing
and range back to the MOB position, not
the active route, until the MOB is can-
celed.
