INTRODUCTION
Your UNIDEN Model PC33X represents
the most advanced Mobile station type
radio ever designed for use in the Citiz
ens Band Radio Service. It will operate
on any of the 40 frequencies designated
as citizens band channels by the De
partment of Communications. Your
Model PC33X features a frequency syn
thesizing circuit with PHASE LOCKED
LOOP techniques to assure ultraprecise
Frequency control. This radio has been
Type Accepted and Type Certified by
the D.O.C.
WARNING
Before transmitting with your transceiv
er, you must obtain a Department of
Communications (D.O.C.) Citizens Ra
dio Licence. Obtain an application
form, from the D.O.C. Before complet
ing the form you should read the condi
tions governing the licensing and oper
ation of the C.R.S. (D.O.C. brochure RB
i 4), This brochure also can be obtained
from the D.O.C, After completing the
application form, mail it with the appro
priate fee to the Superintendant Regu
latory of Licensing in the State or territo
ry in which the station will be operated.
CONTROLS AND THEIR FUNCTIONS
1. HF POWER/"S" METER: This
Light Emitting Diode (LED) meter
shows the Radio Frequency power
when transmitting and the
strength of the incoming signal
when receiving.
2. CHANNEL INDICATOR: Light
Emitting Diode (LED) indicates the
channel number in use.
3. PRESS-TO-TALK MICRO
PHONE: The receiver and trans
mitter are controlled by the press-
to-talk switch on the microphone.
Press the switch to activate the
transmitter; release the switch to
receive. When transmitting, hold
the microphone two inches from
the mouth and speak clearly in a
normalvoice. The microphone pro
vided with your radio is a detach
able low impedance dynamic type.
4. OFF/VOL, CONTROL: Turn
clockwise to apply power to the ra
dio and to set the audio volume to
the desired listening level. Turn
fully counter clockwise to turn the
radio OFF.
® (D (2) ®
SQUELCH CONTROL; This
Squelch Control is rotated to cut off
or eliminate received background
noise in the absence of an incoming
signal. For maximum receive sensi
tivity, it is desired that the control
be rotated only to this point where
the receive background noise or
ambient background noise is elimi
nated. Turn the control fully coun
ter clockwise, then slowly rotate
clockwise until the receive noise
disappears. Any signal to be heard
must now be slightly stronger than
the average received noise. Further
clockwise rotation will increase the
threshold level which a signal must
overcome in orderto be heard. On
ly strong signals will be heard at the
maximum clockwise setting.
6.
ANl/OFF SWITCH: When placed
in the ANL position the Automatic
Noise Limiter circuit is activated.
The ANL circuit reduces impulse
noise.
CHANNEL SELECTOR SWITCH:
7.
This switch selects the desired
channel for transmission and recep
tion. All channels, except channel
9, may be used for communications
between stations operating under
different license, Channel 9 has
been reserved by the D.O.C. for
emergency communications involv
ing the immediate safety of individ-

female connector permits connec
tion of the transmission line cable
male connector (PL-259) to the
transceiver.
10. POWER CORD; A power cord is
supplied with the radio.
uals or immediate protection of
property. Channel 9 also may be
used to render assistance to a mo
torist. This in a D.O.C. rule and ap
plies to all operators of citizens
band radios,
8. TX INDICATOR; Light Emitting
Diode (LED) which indicates the
mode of operating. It indicates red

11. EXTERNAL SPEAKER: The Exter
nal Speaker Jack is used for remote
receiver monitoring. The external
speaker syould have 8-ohm imped
ance and be rated to handle at least
4.0 watts. When the external
speaker is plugged in, the internal
speaker is automatically discon
nected.
