PRO-22
(200-0103)                 Preparation                Faxback Doc. # 39628


To use your POCKET-SCAN, you must do three things:

    Install the batteries

    Connect one of the antennas supplied

    Install 1 to 6 crystals

To install the batteries, position the Receiver as illustrated, press in
the (Down Arrow mark), and slide the BATTERY/CRYSTAL COMPARTMENT COVER
off.

Take out the Battery Holder.  Insert four fresh AA batteries, one at a
time, making sure the polarity markings inside the HOLDER match up
(+ to + and - to -) with markings on the batteries.

We recommend that you use rechargeable Nickel Cadmium AA batteries,
Radio Shack Catalog Number 23-125, or AA Alkaline ENERCELLs,
Catalog Number 23-552.

Two antennas are provided with the PRO-22: a flexible "rubber duck"
antenna and a telescoping one.  The flexible antenna is for use in cramped
areas or wherever a longer antenna would get in the way.  The telescoping
antenna is for obtaining the very best possible reception from your
receiver.  The telescoping antenna must be extended fully for proper
operation.

Crystals are not included with your POCKET-SCAN because the frequencies
are so numerous.  The frequencies used in your part of the country will be
different from those used in other areas.  Your Radio Shack Store Manager
will advise you as to what frequencies are most used and help you in your
selection of crystals.

Insert crystals into the crystal socket.  You can install up to
6 crystals; set the band selector switch for each crystal socket to
either VHF Lo/Aircraft/Hi or UHF. 

    For VHF Lo, set the band selector switch to L
    (marked "L" on printed circuit board).

    For UHF, set the band selector switch to U
    (marked "U" on printed circuit board).

In the example shown, Channel 1 will be used with a VHF Aircraft crystal
and Channel 6 will be used with a UHF crystal.

Since crystal frequencies must be extremely accurate and crystals should
be matched for specific units, we recommend you obtain crystals for your
POCKET-SCAN only from Radio Shack.  Be sure to specify the Catalog Number
and Model description of your Monitor Receiver.  We can not be responsible
for the poor or improper operation of crystals from any other
manufacturer.

CONTROL LOCATIONS AND FUNCTIONS

    OFF-VOLUME

    is the power switch and volume control.  When not in use, rotate this
    control to the left to turn unit off.

    SQUELCH

    control is to eliminate annoying background noise between signal
    transmissions.  When properly set, SQUELCH will keep your PRO-22
    silent until all signal comes in on the channels(s) you are listening
    to-then, the SQUELCH circuit will "open" and you will hear the signal.

    MANUAL Selector Button -

    when the SCAN/MANUAL button is in the MANUAL position, use this button
    to advance the Receiver to the next channel in sequence.  Each time
    you press this button, the Receiver will advance just one channel.

    SCAN/MANUAL Switch

    is for determining the function of the scanning feature.  In the SCAN
    position, each channel will be scanned automatically.  In the ANNUAL
    position, the PRO-22 will not scan, but will remain tuned to the
    channel indicated by a LED Channel Indicator.

    Channel Lock-Out Switches -

    let you activate the four channels individually.  When a switch is up
    (next to LED), that Channel will be scanned for messages in either
    automatic or manual mode; when switch is down, that channel will be
    skipped ("locked out") by the scanner.  When a channel is vacant
    (no crystal plugged in) or when you do not want to monitor that
    channel, leave its switch down.  Otherwise leave the switches in the
    "up" position.

    LED Channel Indicators -

    show which channel is currently being scanned or monitored.
    Each channel indicator will light up for an instant as it is scanned;
    if there is a message on that channel, the LED will remain lit until
    message is over and scanning resumes.  Locked-out channels will not
    be scanned; therefore their indicators will not light up.

    EARphone jack

    Is for plugging in the earphone.  Use it for private listening or in
    areas where background noise is excessive (in factories, at the scene
    of an accident or fire, in a vehicle, etc.).  Plugging in the Earphone
    disconnects the PRO-22's internal speaker.

    ANTenna jack

    Is for connecting an antenna to the PRO-22.  You can use either the
    telescopic antenna or flexible antenna provided.

    A Belt Clip

    Is provided so you can attach the PRO-22 to your belt or other
    convenient place.

    Battery Compartment

    Holds the internal power source (4 type AA batteries).

    Crystal Compartment

    Contains crystals selected for operation.

    External PoWeR Jack

    Lets you connect an external source of 6 volts DC (negative ground)
    for operation without batteries.

    To recharge Nickel Cadmium batteries in the receiver, simply plug an
    external 6 volt DC power source into the CHG JACK.  To fully charge
    Ni-Cads, leave them on charge for 10-18 hours.

    NOTE

    The Recharge (CHG) jack

    is to be used only when Nickel Cadmium batteries are installed in the
    receiver.  Also, do not attempt to operate the unit while recharging
    Ni-Cads.
