Digital Select Calling (DSC) Setup
•
Digital Selective Calling (DSC) uses digital signals to increase messaging range. This
provides the most reliable message delivery per watt of output power. Digital signals
are less susceptible to distortion from noise and atmospheric conditions than analog
signals.
DSC equipped radios also interface with GPS and automate many operations for
sending and receiving messages. This results in compact, accurate messages and
less airwave congestion.
Setup procedures for all DSC features use the Setup menu. Refer to page 40 for
information on entering and exiting the Setup menu.
User MMSI Number
The nine (9) digit MMSI number, similar to a telephone number, is a unique identifier
for a vessel. DSC incorporates this number into every message that is Sent (Tx) or
Received (Rx). Enter the MMSI number as soon as you receive your MMSI number
from the issuing agency listed on page 9.
NOTE
The radio does not operate in the DSC mode until an official MMSI number is
entered. An error tone will sound when attempting to operate in the DSC
mode without an MMSI number.
NOTE
An MMSI number can only be entered one time. To create a new MMSI
number, the unit must be reset by the dealer.
