Appendix D - MMSI and License Information
You must obtain a user MMSI (Marine Mobile Service Identity) and enter it into your RS10
in order to use the DSC functions. Contact the appropriate authorities in your country. If
you are unsure who to contact, consult your Simrad dealer.
The user MMSI 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 RS10. You
may also need an individual operator's license.
Simrad recommends that you check the requirements of your national radio com-
munications authorities before operating DSC functions.
