FM 4800 reset MMSI

[The Mitten]

I bought a used FM 4800, mostly because I could not get a new one. After receiving it I realized it already has an MMSI number programmed and the user manual says this is a one time thing. Can Furuno walk me through a reset, or will the unit have to be sent in?

It would need to be reflagged by an authorized Furuno dealer or service center.
