Microphone Preamp
This
microphone
may
be used with any Trio-Kenwood
radio.
It is intended especially for FM and SSB mobile
radios. The preamp is controlled by the bottom mounted
switch on the base unit. Sliding the switch forward places
the preamp on. Sliding the switch to the rear bypasses the
ON > OFF
preamp
and
disconnects
the batteries. With the preamp
switch on, power is always on so the microphone may be
used with VOX operated equipment.
NOTE:
To conserve battery power, turn the preamp off
when
not in use.
(The amplifiers draw approxi-
mately 1 ma.)
