I have a question about the m c 60 A. I have one and I tried to use it on my 
t m v 71 A. I got reports of low audio when I used it. As those who own a t 
m v 71 A know, it has an r j 45 connector. I used an eight pin to r j 45 
adapter. Could that be the reason for the low audio? Presently, there are no 
AA batteries in the mic. What part of the mic has to be taken apart in order 
to install the batteries? I'd like to use the mic on the radio but I don't 
want to have to quote kiss the mic in order to use it. Any help from fellow 
listers would be welcomed. Doug, N6NFF

Mark,
I googled for MC60 manual and extracted the portion you need.  See below.

Microphone Preamplifier

You can use this microphone with any KENWOOD transceiver. It has been
designed especially for FM and SSB mobile transceivers. You can
control the preamplifier

using the MIC AMP IN/OUT switch on the inside of the base of the 
transceiver.

First renove the base of the microphone, then slide the switch to the
IN position to turn the preamplifier ON. With the switch in the OUT
position, the preamplifier is bypassed and the batteries are
disconnected. To conserve battery power, turn the preamplifier OFF
when it is not in use.
