@ FEATURES
The MC-60A
microphone is designed expressly for use with
your amateur
communication
system.
It provides excellent
performance
when
used
with
any
KENWOOD
transceiver,
thereby upgrading your existing system.
The zinc die-cast base offers high stability, and is complete
with a feather-touch
PTT switch, rocker UP/DOWN
switch,
an impedance selector switch and a built-in preamplifier.
NOTE:
For
UP/DOWN
switch
operation,
refer
to your
transceiver's manual.
CAUTION:
1. The microphone
is constructed of precision parts. Do not
open the microphone, as it may result in serious damage.
2. The
microphone
is sensitive
to
shock
and
vibration.
Treat
it gently.

1. Battery Installation (Fig. 2)
1. Remove four screws as shown.
2. Install
two
alkaline
AA
celis (not NiCd).
Observe
polarity.
3. Reassemble
base
unit.
NOTE:
1. Radios with power
available at the mic con-
nector (for autopatch microphones)
will not

may also be used separate from the
base unit, by connecting
the retractile cord directly
to the mic. However, the preamp
is located
in the
base unit. Preamped
operation
is not possible with a
direct transceiver hookup.
5. The MC-60A
is supplied with a standard PG-4C 8 pin
to 8 pin retractile cord. For radios with a four pin mic
