iv Ray54E VHF Radio
Important Information
Maritime Mobile Service Identity (MMSI)
The Ray54E includes equipment for Class “D” Digital Selective Calling
(DSC). A nine-digit Maritime Mobile Service Identity (MMSI) number is
required to operate the DSC equipment. In some areas, a radio operator
licence is required before an MMSI number will be issued.
Note: You can request an MMSI number fromsame agency that issues radio
or Ship Radio licences in your area. Once obtained, you can program the
MMSI number into your Ray54E as described in this handbook.
Group MMSI ID
A Group ID MMSI number can also be entered for vessels that are part of a
group, such as a flotilla or racing fleet, enabling DSC communications within
the group.
Automatic Transmitter Identification System (ATIS)
If you purchased your Ray54E to include use on the inland waterways of the
contracting governments of the “Regional Arrangement Concerning the
Radiotelephone Service on Inland Waterways”— also known as the Basel
Agreement
1
— your Ray54E will be programmed by your dealer to include
Automatic Transmitter Identification System (ATIS) functionality. ATIS
includes data at the end of radio transmission that identifies your station.
ATIS operation can be turned on or off as needed via the radio’s Menu mode.
Note: When ATIS is enabled, certain programming steps have been imple-
mented to protect the integrity of the Basel Agreement, including the block-
ing of DSC functions when ATIS is active. See Digital Selective Calling
(DSC) on page 31 and ATIS Function on page 79.
Your ATIS ID number is derived from your vessel’s call sign. Your
authorized Raymarine dealer can assist you in decoding your ATIS ID
number, which you can then program into your Ray54E using the operation
described on page 77.
