You'll hear all the action with your new
~W=LIS~=! PRO-30Pro-
grammable Scanning Receiver! You'll have direct access to 23,684
different frequencies in nine action radio bands-police, fire, ambu-
lance, aircraft, ham radio, and transportation services! And you can
program your PRO-30 to scan up to 16 channels so you won't miss
any of the excitement.
The secret to the PRO-30
is a custom-designed microprocessor-a
computer on
a chip! The front panel keyboard lets you easily enter
and change frequencies whenever you wish. The microprocessor also
gives you special functions not found on other scanning receivers.
Curious about what's on the air in your area? The PRO-30will auto-
matically search for active stations in frequency rangesof your choice;
you can locate new stations and services easily! And if there's
a
frequency you're especially interested in, the PR lority key will make
sure you never miss
a call on it. You can listenor scan other channels
and your PRO-30will automatically switch tothe PR I0
R ITYchannel
when
a call is receivedon it!
Other features you'll appreciate include Lockout to skip over
channelsduring scanning and fastlslow search and scanning rates.
Your PRO-30 achieves
its superior performance through the use of
the very latest in solid-state technology. In addition to the micro-
processor, the PRO-30 includes a phase-locked loop (PLL) IC,
4
C-MOS ICs including microprocessor, 5 integated circuits, 39 transis-
tors, 75 diodes and
a Liquid Crystal Display.

FEATURES INCLUDE:
* Covers 30 - 50 MHz (VHF Lo), 50 - 54 MHz (ham radio 6m),
108 - 136 MHz (aircraft), 138 - 144 MHz (government), 144 -
148 MHz (ham radio 2m), 148 - 174 MHz (VHF Hi), 380 - 450
(ham radio and government), 450 - 470 MHz (UHF Lo) and 470 -
51 2 MHz (UHF Hi) - 23,684 channels!
*
Scan up to 16channelscontinuously.
* Search feature scans frequency ranges for new stations.
*
Priority function means you'll never miss a call on your favorite
channel!
*
Large multi-purpose Liquid Crystal Display shows which channels
and frequencies are being scanned, monitored or programmed as
well as the statusof the Channels.
*
Channel Lockout function with built-in skipper circuit.
* Two-secondscan delay function eliminates missed replies.
*
Crystal filter for 1st IF (10.7 MHz) plus ceramic filter for 2nd IF
(455 kHz).
* Battery backup holds memorized frequencies even if the main
battery weakens.

The Battery Compartment holds the internal power source (6 type
AA batteriesplus three silver oxide batteriesfor memory back-up).
External PoWeR Jack lets you connect an external source of 9 volts
DC (negative ground) for operation without batteries. Use our 273-
1455 for 120VAC, 14-844D for 12V Car operation. Mobile use of
scanners in some areas may be unlawful or require a permit. Check
with local authorities.
To recharge Nickel Cadmium batteries in the receiver, simply plug
an external
9 volt DC power source (Such as our 273-1455 noted
above) into the CHarGe JACK. To fully charge Nickel Cadmiums,
leave connected for 10-1 8 hours.
Cadmium batteries are installed in the receiver. Also, do not
attempt tooperatethe unit while rechargingNickel Cadmiums.

PREPARATION FOR USE
To install the batteries, position the Receiver as illustrated, press in
the
EE3 mark, and slide the battery compartment cover off. Take
out the battery holder for AA cells. On the bottom of the compart-
ment
is a cover for back-upbattery compartment. Slide to open.
Insert three back-up batteries (Catalog Number 23-101 or equivalent)
with flat
- side toward bottom and push the reset switch (inside
battery compartment). Replace the back-upbattery cover.
Insert
6 fresh AA batteries into the battery holder, making sure the
polarity markings inside the holder match up
(+ to + and - to -)
with markings on the batteries. Replace the battery holder and the
battery compartment cover.
We recommend that you use rechargeable Nickel-Cadmium AA bat-
teries, Catalog Number 23-125, or AA Alkaline ENERCELLs, Catalog
Number 23-552.
LOW BATT indicator flickers and sounds an alarm when the battery is
low. Replace or recharge batteries. Memory back-upbatteriesshould
be replaced once a year.

If you wish to use your PRO-30with an external antenna such as a
mobile antenna or outdoor base antenna, removethe flexible antenna
and you can connect
it tothe BNC connector on the PRO-30.
Pressing the reset button located in the battery compartment will
clear
all frequenciesfrom the scanner memory.
Press this button, using
a pen or pencil, before using the scanner
for the first time.

OPERATING YOUR PRO-30
Turn on your PRO-30by rotatingVOLUME clockwise.
(Whenfirst turned on, your
PRO-30 might start scanning.)
Rotate SQUELCH fully counterclockwise. You'll hear
a rushingnoise
from the speaker. Slowly rotate SQUELCH clockwise until the noise
just stops. You're now ready tostart entering frequencies!
Understandingthe Display
The liquid crystal display on your PRO-30 can display the channel
number, the frequency being received, and the status of different
functions Here's
a brief rundown on what those symbols mean when
receivingstations.
