WARNING:  Do not connect or remove the CMP30 (RAM3) microphone while 

the radio is powered on. This may result in equipment failure.

1.  Connect  the  Extension  Cable  to  the  8-pin  connector  on  the  transceivers  rear 

panel, then tighten the Cable Nut (Figure 1).

2.  Referring to Figure 2, attach the supplied ferrite core as close as possible to the 

MIC plug of the Routing Cable and External Speaker Connections, then snap its 
two halves together. And then, wind some plastic tape around the ferrite core, to 
prevent vibration from causing the two halves to split apart and fall off the wires.

3.  Referring to Figure 3, make a 1.2” (30 mm) hole in the wall then insert the Exten

-

sion Cable into this hole. Connect the Gasket and Mount Base to the Extension 
Cable Connector using the Nut.

4.  Drill the four Screw holes (approx. 2 mm) on the wall then install the Mounting 

Bracket to the wall using four screws.

5.  Put the Rubber Cap on to the Nut.
6.  The installation is now complete. Connect the 

RAM3

 (
