Re: CDM1550 Remote Head Issue

The board just kind of snaps into the head, then the remote kit adapter should hold it in place. It can be a bit tricky the first time you do one, the board will sometimes pop out a bit when you try to put the head onto the remote kit or the radio. You have to makes sure the board is seated all the ...

This should be where the fuse F0401 is, near the connector that the control head plugs into. It's a 3A surface mount fuse. It can be tested with an ohmmeter (with power disconnected from the radio of course).
