I am shortly going to be selling my RO4800 AIS VHF radio. I did a quick google for reset instructions to remove my mmsi etc. The above came up.
Hold Band and Watch button in whilst switching on, let them go and a menu comes up asking for the pin, choose with the rotary knob, 1 enter 6 enter 8 enter 8 enter. Then choose an option to remove mmsi, edit or factory reset.
