Question about Icom Radio Communications
This secret code is for the Raytheon / Raymarine RAY 220 VHF. It may work on other Raytheon/Raymarine radios also.
Here you go:
With the Power OFF, Press and HOLD the FUNC, 16/9 and DSC keys while you power ON. Do not release the keys until you hear the audio BEEP which means your done. Then reprogam your NMSI number as per the manual. Pretty easy, hey?

SOURCE: need to reset the mmsi
Did you ever solve this problem. I have just purchased a little Leisure 17-SL with a fairly new one of theses radios. I have the handbook and discover you can only program the MMSI once and then return to a dealer to clear it!
