Recalls last call regardless of which type of call was received last.
Allows you to make a new call, either by entering an MMSI number
or by selecting a number from the Contact List.
Sends transmissions that are only received by radios that share a
common group MMSI number; up to 3 group MMSI numbers can
be stored and called.
Make an Urgency, Safety, or Routine call to all DSC-enabled ships
or ships within communication range. A re-confirmation screen will
be displayed after you choose one of these three call types. You
should send an All Ships call when assistance is needed but the
situation is not serious enough for a Distress Call. An Urgency call
is made when assistance is required but the situation is not life-
threatening, while a Safety call is for an advisory alert.
Allows a review of the last 20 stored calls by number and time of
call. An individual call type can be placed to the selected
MMSI/NAME in the LOG. The LOG maintains all received call types
except DISTRESS calls. The earliest call is stored at the end of the
list (20 maximum), and is automatically erased when a new call
comes in.
Allows a review of the last 10 stored Distress calls by number and
time of call. The earliest call is stored at the end of the list (10
maximum), and is automatically erased when a new call comes in.
Allows you to request GPS position information from any vessel for
which an MMSI number is known; you can either pick the MMSI
number of the vessel from the Contact List, which is a personal
DSC directory of saved MMSIs, or by manual entry.
Quits the DSC Call Type menu mode.
