INTRODUCTION

Your new RadioShack PRO-2066 150-Channel Mobile Trunking Scanner is one of
a new generation of scanners designed to track Motorola Type 1 and Type II
(such as Smartnet and Privacy Plus) and hybrid analog trunking systems,
which are extensively used in many 800 MHz communication systems.

Trunking communications systems let a large group of 2-way radio users (or
even different groups of 2-way radio users) efficiently use a large range
of frequencies.  Instead of selecting a specific frequency for a
transmission, the user simply selects a talk group.  The trunking system
automatically transmits the call on the first available frequency, and
also sends (on a different frequency called a data channel) a code that
uniquely identifies that transmission.

Since the trunking system might send a call and its response on different
frequencies, it is difficult to listen to trunked communications using a
regular scanner.  The PRO-2066 lets you select and monitor the data
channel frequency sent with a 2-way radio transmission, so you can hear
the call and response for that user and more easily "follow" the
conversation.

The scanner also lets you scan conventional transmissions, and is
preprogrammed with service banks for convenience.  By pressing a single
button, you can quickly search those frequencies most commonly used by
public service and other agencies without tedious and complicated
programming.

This scanner gives you direct access to over 30,000 exciting frequencies,
including police and fire departments, ambulance services, and amateur
radio services, and you can change your selection at any time.

Your scanner also has these special features:

        CB Receive with Channel Display - you can scan CB transmissions,
                                          displaying the channel number as
                                          you scan them.

                     Nine Service Banks - frequencies are preset in
                                          separate police
                                          (fire/emergency), aircraft, ham,
                                          marine, public, CB highway, DOT
                                          (department of transportation),
                                          and weather banks, to make it
                                          easy to locate specific types of
                                          calls.

                             DIN-E Size - you can install the scanner in
                                          the mounting space provided in
                                          many new vehicles.

               Supplied Frequency Guide - lists the frequencies for many
                                          of the 800 MHz public safety
                                          systems you can listen to.

            Triple-Conversion Circuitry - virtually eliminates any
                                          interference from IF
                                          (intermediate frequency) images,
                                          so you hear only the selected
                                          frequency.

             Five Channel-Storage Banks - you can store up to 30 channels
                                          in each of 5 different banks to
                                          group channels so you can more
                                          easily identify calls.

                        Five Scan Lists - you can store up to 50 trunking
                                          IDs in each trunk tracking bank.

                  Two-Second Scan Delay - delays scanning for about 2
                                          seconds before moving to another
                                          channel, so you can hear more
                                          replies that are made on the
                                          same channel.

                      Lock-Out Function - lets you set your scanner to
                                          skip over specified channels or
                                          frequencies when scanning or
                                          searching, and skip over IDs
                                          when tracking trunked systems.

                      Priority Channels - lets you program one channel in
                                          each bank (5 in all) and then
                                          have the scanner check that
                                          channel every 2 seconds while it
                                          scans the bank, so you don't
                                          miss transmissions on those
                                          channels.

                            Hypersearch - lets you set the scanner to
                                          search at up to 300 steps per
                                          second in frequency bands with 5
                                          kHz steps.  The normal search
                                          speed is 100 steps per second.

                              Hyperscan - the scanner automatically scans
                                          up to 50 channels per second to
                                          help you quickly find
                                          interesting broadcasts.

                       Data Signal Skip - lets you set the scanner to skip
                                          non-modulated or data signals
                                          (such as fax or modem
                                          transmissions) during scanning
                                          or searches.  This lets the
                                          scanner avoid non-voice signals,
                                          making a scanning oar search
                                          faster.

                  Manual Channel Access - You can directly access any
                                          channel to quickly tune a
                                          frequency stored in the channel.

                 Disconnect Tone Detect - the scanner automatically tunes
                                          to the trunking data channel
                                          when it receives a disconnect
                                          transmission.  You can turn this
                                          off, to let you monitor a
                                          channel with a weak transmission
                                          where conversations are often
                                          disconnected.

                 Liquid-Crystal Display - makes it easy to view and change
                                          programming information.

                      Display Backlight - makes the scanner easy to read
                                          in low-light situations.

                       Monitor Memories - lets you temporarily store up to
                                          5 frequencies or IDs.

                          Memory Backup - keeps the frequencies stored in
                                          memory for an extended time if
                                          the PRO-2066 loses power.

                 Key Confirmation Tones - the scanner sounds a tone when
                                          you perform an operation
                                          correctly, and an error tone if
                                          you make an error.

We recommend you record your scanner's serial number here. The number is
on the scanner's back panel.

FCC NOTICE

Your scanner might cause TV or radio interference even when it is
operating properly.  To determine whether your scanner is causing the
interference, turn off your scanner.  If the interference goes away, your
scanner is causing it.  Try to eliminate the interference by:

  moving  your scanner away from the receiver.

  connecting your scanner to an outlet that is on a different electrical
  circuit from the receiver.

  contacting your local RadioShack store for help.

If you cannot eliminate the interference, the FCC requires that you stop
using your scanner.

This device complies with Part 15 of the FCC Rules.  Operation is subject
to the following two conditions:

  (1)  This device may not cause harmful interference and

  (2)  This device must accept any interference received, including
       interference that may cause undesired operation.

SCANNING LEGALLY

Your scanner covers frequencies used by many different groups including
police and fire departments, ambulance services, government agencies,
private companies, amateur radio services, military operations, pager
services, and wireline (telephone and telegraph) service providers.  It is
legal to listen to almost every transmission your scanner can receive.
However, there are some transmissions you should never intentionally
listen to.  These include:

  telephone conversations (cellular cordless, or other private means of
  telephone signal transmission).

  pager transmissions.

  any scrambled or encrypted transmissions.

According to the Electronic Communications Privacy Act (ECPA), you are
subject to fines and possible imprisonment for intentionally listening to,
using, or divulging the contents of such a transmission unless you have
the consent of a party to the communication (unless such activity is
otherwise illegal).

This scanner has been designed to prevent reception of illegal
transmissions.  This is done to comply with the legal requirement that
scanners be manufactured so as to not be easily modifiable to pick up
those transmissions.  Do not open your scanner's case to make any
modifications that could allow it to pick up transmissions that it is not
legal to listen to.  Doing so could subject you to legal penalties.

We encourage responsible, legal scanner use.
