Possible Causes Possible Solutions
MMSI number not programmed. Programme your MMSI number. Each VHF radio requires a unique MMSI number. In the United States,
this MUST be programmed into the unit by an authorized dealer. For more information, refer to: Obtain
MMSI (Maritime Mobile Service Identity) number
Radio is set to ATIS or Marcom-C mode. Use of DSC is not permitted when in ATIS or Marcom-C mode. You will be unable to make DSC distress
and other types of digital selective call.
If you are not in an ATIS region switch off ATIS mode:
Menu > Set-up > ATIS set-up > ATIS.
Obtain MMSI (Maritime Mobile Service
Identity) number
Before commencing installation ensure you have
obtained an MMSI number for your vessel.
An MMSI is a 9 digit number which is sent over a radio
frequency channel in order to identify the originating
vessel/station. If your vessel already has an MMSI
number (used for a VHF DSC radio) then the same MMSI
number must be used to program your product.
Note:
If an MMSI number is not entered, the DSC
functionality of your radio will be disabled.
In the United States of America, the MMSI and Static
Data must be entered only by a Raymarine® dealer
or other appropriately qualified installer of marine
communications equipment on board vessels.
The user is NOT authorized to do this.
In some areas, a radio operator licence is required
before an MMSI number will be issued. You can request
an MMSI number from same agency that issues radio or
Ship Radio licences in your area.
In Europe and other parts of the world outside of the
United States of America, the MMSI and Static data can
be set up by the user.
For further details, refer to the relevant
Telecommunications Regulatory Body for your
area.
Refer to Appendix C MMSI Regulatory bodies and
application submissions
for a list of contacts for obtaining MMSI numbers for
some areas.
