Microphone Connector. The electrical con-
nections between the microphone and unit
are made via
this
connector, to permit
removal of the microphone as desired.
VOLUME Control. Permits varying the sound
output from the speaker to suit your indi-
vidual desire. A switch at the counterclock-
wise end of rotation disconnects the unit from
its power source.
TUNING Control. Permits the receiver to be
tuned at will. Note that this control has NO
effect on transmitter frequency.
TRANSMIT -RECEIVE Switch. The middle,
or RECEIVE position actuates the receiver
section
of
the HW-30. Pushing the knob
down permits short transmissions of an inter-
mittent nature, and is comparable to a simi-
lar function provided in many intercoms.
Lifting up allows continuous transmission for
longer periods of time without continuous
pressure. This position would normally be
used primarily for mobile operation. Both
TRANSMIT positions perform the same func-
tions electrically.
