11  DIGITAL SELECTIVE CALLING
11.1  GENERAL
WARNING
This radio is designed to generate a digital maritime distress and safety
call to facilitate search and rescue. To be effective as a safety device,
this equipment must be used only within communication range of a shore-
based VHF marine channel 70 distress and safety watch system. The
range of signal may vary but under normal conditions should be approxi-
mately 20 nautical miles.
NOTE
A DSC Warning sticker is included
with the GX3500S. To comply with
FCC regulations this sticker must be
mounted in a location that can be eas-
ily viewed from the location of the
GX3500S. Make sure the chosen lo-
cation is clean and dry before apply-
ing the sticker.
Digital Selective Calling is a semi-automated method of establishing a radio
call, it has been designated by the International Maritime Organization (IMO)
as an international standard for establishing VHF, MF and HF radio calls. It has
also been designated as part of the Global Maritime Distress and Safety Sys-
tem (GMDSS). It is planned that DSC will eventually replace aural watches on
distress frequencies and will be used to announce routine and urgent maritime
safety information broadcasts.
This new system allows mariners to instantly send a distress call with GPS posi-
tion (when connected to the transceiver) to the Coast Guard and other vessels
within range of the transmission. DSC will also allow mariners to initiate or receive
Distress, Urgency, Safety, Routine, POSITION REQUEST, POSITION SEND, and
Group calls to or from another vessel equipped with a DSC transceiver.

11.2  MARITIME MOBILE SERVICE IDENTITY (MMSI)
11.2.1  What is an MMSI?
An MMSI is a nine digit number used on Marine Transceivers capable of using
Digital Selective Calling (DSC). This number is used like a telephone number to
selectively call other vessels.
THIS NUMBER MUST BE PROGRAMMED INTO THE RADIO TO OPERATE
THE GX3500S DSC FUCTIONS.
How can I obtain an MMSI assignment?
Boat US offers online registration of a MMSI. Visit www.boatus.com/mmsi
11.2.2 Programming the MMSI
WARNING
User MMSI can be input only twice. If the user tries to input an MMSI
more than twice, the radio will show the display on
the right. If the user needs to change the MMSI
more than twice, the transceiver will have to be
sent to Factory Service. Refer to the section “14.2.
FACTORY SERVICE.”

to all DSC radios. The GX3500S may be connected to a GPS to also transmit
the Latitude, Longitude of the vessel.
11.3.1 Transmitting a DSC Distress Call
NOTE
To be able to transmit a DSC distress call an MMSI number must be
programmed, refer to section “11.2.2 Programming the MMSI.”

”
icon will appear on the LCD. After the message has
been sent, the radio will sound a Distress Alarm.
4. The transceiver will watch for a DSC acknowledg-
ment transmission on CH70 and also receive calls
on CH16.
5. If an acknowledgement is received, select channel
16 and advise your distress situation.
6. If no acknowledgment is received, the distress call is
repeated in 4 minute intervals until a DSC acknowl-
edgment is received.

The All Ships Call function allows contact to be established with other vessel
stations without having their ID in the individual calling directory. Also, priority
for the call can be designated as Urgency or Safety.
URGENCY Call: This type of call is used when a vessel may not truly be in
distress, but have a potential problem that may lead to a dis-
tress situation. This call is the same as saying PAN PAN PAN
on channel 16.
SAFETY Call: Used to transmit boating safety information to other vessels.
This message usually contains information about an overdue
boat, debris in the water, loss of a navigation aid or an impor-
tant meteorological message. This call is the same as saying
Securite, Securite, Securite.”
