Appendix D - MMSID and License Information

You must obtain a user MMSID (Marine Mobile Service Identity) and enter it into your radio in order to use the DSC functions. Contact the appropriate authorities in your country. If you’re unsure who to contact, consult your Northstar dealer.

The user MMSID is a unique nine digit number, similar to a personal telephone number. It is used on marine transceivers that are capable of using DSC (Digital Select Calling).

Depending upon your location, you may need a radio station license for the VHF 721. You may also need an individual operator’s license.

Brunswick New Technologies Inc. recommends that you check the requirements of your national radio communications authorities before operating DSC functions.
