Channel Selector . . . use to select any one of the standard 18 CB channels.
MON-PA-CB Switch . . . Controls the function of the audio amplifier/modulation circuitry when the
Microphone button is pressed. When the slide switch is in the "CB" position, the Microphone button
turns the Transmitter on for normal transmissions. When set to 'PA' position, the Transmitter will not
function -- the Microphone turns on the Public Address Amplifier function. For PA operation you must
have a PA speaker connected to the PA jack on the rear chassis. When set to 'MON' position, you can use
the PA function and yet can monitor CB incoming signals.
NB slide Switch (Noise Blanker) . . Set to NB to cut out annoying impulse-type noise. Set to OUT to
release this function. This is particularly effective for ignition noise on both AM and SSB.
R F-S Meter . . . give visual indication of signal strengths. When receiving, the RF-S Meter shows the
strength of incoming signals; a change of one "S" unit indicates a change of 6 dB in signal strength.
The meter is set up so that a 100 microvolt signal will produce a reading of S-9. When Transmitting,
the R F-S meter gives a relative indication of output power from the Transmitter.
THE REAR PANEL
PA SPeaker Jack . . . connect an 8-ohm Public Address speaker to this jack for PA use. We recom-
mend TANDY 40-1244, weatherized, rugged PA Speaker, as an ideal unit for either PA or External
Speaker application.
EXTernal SPeaker Jack . . . if you want to use an external speaker, plug it into this jack. You should
use a standard 8 ohm type. When an external speaker connected to this jack, the built-in speaker is
automatically disconnected.
ANTENNA Coax Connector . . . connect your CB antenna to this (SO-239 type, accepts PL-259 con-
nectors).
12V DC connector and Power Cable with in-line fuse . . . this cable is to be connected to a source of
12-16 volts DC power, negative or positive ground. The Red wire with the in-line fuse must be con-
nected to the + side and the Black wire to the — side.
