FEATURES
Your RadioShack
Channel CB Mobile Transceiver is a
breakthrough in CB design technolo-
gy. It includes a DSP (Digital Signal
Processor) circuit for improved audio
quality, which reduces background
noise and virtually eliminates the
whines and whistles commonly heard
on crowded CB frequencies.
Your CB also has these advanced fea-
tures:
DSP Switch and Indicator — turns
the DSP circuit on and off and shows
the on/off status of the circuit.
Phase-Locked Loop (PLL) Frequen-
cy Synthesizer — provides highly ac-
curate and stable tuning.
Two Built-In Ceramic Filters — en-
sure superior channel selectivity and
freedom from adjacent channel inter-
ference.
Automatic Modulation Control —
prevents the transmitter signal from
over-modulating and distorting.
Automatic Noise Limiter — reduces
impulse-type noises while receiving.
Large, Illuminated, Digital Display
— clearly shows the channel number.
