(4) Squelch Control
This knob Is to be used to determine how strong an
incoming CB transmission must be to automatically
"break-through" the radio or tape program being
listened
to. At low squelch settings almost all signals will
be received (Including background carrier noise on
occasions). Higher settings require astronger Incoming
signal
to break through. Some experimentation will be
necessary to find a suitable compromise. The squelch
control has
no effect on outgoing CB transmissions.
Rotating' the control lully counter-ckockwise unlll a
"click" Is felt will completely turn 011 the CB and the CB
display.
(5) 'PA Selector

LI D(Local-Distant·)Selector ,
This control functions In radio and"'CB operation. In
essence, It reduces the reception capability of the radio
and CB In the "Local" mode
so that only strong signals
can be received. When the bullon Is In the
"local" mode,
It will be indicated by Illuminating a dot on the LED"panel
next to the "LO" symbol. Whenever the switch Is In the
. "Distant" mode, maximum reception capability Is
achieved. The setting of this bullon will also effect the
automatic "Seek" tuning operation by limiting
or Increas-
ing the amount of radio stations the system will "seek"
in radio mode.
F
IT (Frequency-Time) Selector

(11) Radio & Function Display Panel
This LED panel provides a visual display of all radio
functions. First it shows which radio frequency Is
selected by displayingthe numerical frequency. Second-
ly by illuminating a small dot near the AM orFM marking
you know which band is selected (the AM also functions
with
PM for time display). Additionally, the "ST" marking
indicates a "Stereo" broadcast while
tti~ "LO" marking
Indicates

Electronic Radio Station Tuning Selectors
To select a radio station, depress either the upward or
downward pointing arrow after observing.. the radio
display panel, A quick depress and release will Increase
(or decrease) the frequency one step while holding the
button in will rapidly advance the digits. Nota: AM radio
stations advance
In 10 KHz steps (530 ... 540 ... 550 ...
etc.) as this is the mandatory spacing required by the FCC
lor radio broadcast stations. FM radio stations advance
in
.2 MHz steps (103.5 ... 103,7 ... 103.9 .. '. etc.) for the
same reason, Nole: For simplfcity, some
FM sta'tions will
advertise their call sign
as an even number (example:
WWDH 104
FM) and you will find you cannol tune to
104,0 FM. Only 103,9 or 104.1 can be selected.This Is not
aproblem of the radio since no FM station canbroadcast
on an even digit frequency. If you listen for
th,e "true"
stations' call frequency,you wUJ.flnd Itwill be, either103,9
or104,1. They have:'roundedItout" to 104for advertising
purposes only. This was not a problem
In the past when
radios
only had a radio dlat with amoving pOlnter,AII you
h<ld to dowas movethe pointernear"104" onthe dlat and
rock It back and forth to "find" the station. 'Today's
electronic tunersare
far more preciseand willloC<lte only
the exacttrue frequency. Fortunately,mostradio stations
realize the confusion they are causing and have begun
broadcasting their "true" frequency.
