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 ap-
proximately 20 nautical miles.
NOTE
A DSC Warning sticker is included with the
GX1000S . To comply with FCC regulations
this sticker must be mounted in a location
that can be easily viewed from the location
of the
GX1000S . Make sure the chosen lo-
cation is clean and dry before applying 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
System (GMDSS). It is planned that DSC will eventually replace aural watches
on distress frequencies and will be used to announce routine and urgent mari-
time safety information broadcasts.
When the radio is shipped from the factory it is programmed so CH70 (the
DSC channel) is scanned at all times.
This new system allows mariners to instantly send a distress call with GPS
position (when a GPS is 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.
