DSC Set-Up
DSC Set-Up
•
Digital selective calling — DSC — employs digital RF signals which tend to carry
further and be less susceptible to distortion from noise and atmospheric conditions
than analog ones. The result is greater range and more reliable message delivery
per watt of output power.
But, that is not the only advantage of DSC equipped radios. Those radios are set up
to interface with GPS and to automate many of the operations involved in sending
and receiving messages. That results in more compact and accurate messages and
less congestion of the airwaves.
The price of these benefits to the user is the time it takes to do the required set-up
to make the DSC features work. A little time spent when your radio is new will pay
dividends over its life.
This radio follows Class D DSC with a dedicated Channel 70 receiver.
These procedures use the Settings menu. Refer to page 35 for information on
entering and exiting the Settings menu.
User MMSI Number
This nine digit number is similar to a telephone number in that it is a unique
identifier for you and your vessel. DSC uses this number in every message it
sends and receives. That is why your radio will not operate in the DSC mode
until you enter your MMSI Number. You should enter it or have your dealer
do so as soon as you receive it from one of the issuing agencies listed on
page 9.
NOTE
Because it is important to correctly enter the MMSI number in the radio,
the following procedure requires that the number be entered, then verified
by entering it again. If the same number is entered both times, the system
will accept it. If the two entries are different, an error message will appear
with a prompt to try again.

Memory Scan
During Memory Scan, the radio will rapidly switch from
tagged channel to tagged channel. Whenever any activity
is detected, the radio will stop the scan for ten seconds to
allow you to listen briefly on that channel. It will then continue
to scan unless you switch out of the Memory Scan mode.
NOTE
If there are fewer than two channels tagged, the Memory
Scan mode will not be available. [See page 43 under
program memory channels to tag at least two channels.]
NOTE
The radio must be squelched for the Memory Scan
mode to function. See page 33 for squelch procedure.
To enter the memory scan:
1. From Standby mode, press the Memory Scan/
Memory Clear button.
The radio will immediately begin to scan the channels you
tagged.
MEM SCAN
(memory scan) will show on the LCD.
To exit the memory scan:
1. From Memory Scan mode, press the Memory
Scan/Memory Clear button.
This will return the radio to Standby mode on the last
scanned memory location.
During memory scan (while receiving an incoming
transmission), you can choose from the following:
a. Press the Talk button to remain on that memory
location and end scanning. This will return the radio
to Standby mode.
b. Press the Up/Down buttons to resume scanning.
If you do not press any buttons within ten seconds,
your radio will automatically resume scanning.
During memory scan (while not receiving a transmission):
