7.10 DIGITAL SELECTIVE CALLING

7.10.1 GENERAL

7.10.1.1 Digital Selective Calling (DSC)

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

had 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

maritime safety information broadcasts.

The HX600S has a DSC Distress feature that allows mariners to instantly

transmit a VHF Marine distress call with GPS position (when connected to

the transceiver) to the US Coast Guard and other vessels within range of the

transmission.

7.10.1.2 Maritime Mobile Service Identity (MMSI)

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 by the HX600S

when a Marine DSC Distress call is transmitted. This number is registered

with the USCG. Refer to section 10 “MENU (“SET”) MODE”(MMSI REG).

NOTE: An MMSI must be programmed into the HX600S before the DSC

Distress function will operate. If you have a fixed mounted DSC VHF and

already have a MMSI, this MMSI should be programmed into the HX600S.

How can I obtain a MMSI assignment?

Currently there are two companies that offer MMSI numbers:

Boat US at (800) 563-1539 or visit the web site

Seatow at (631) 765-3660 or visit the web site

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.
