Introduction

Your new RadioShack PRO-2052 1000-Channel Dual Trunking Trunk-Tracker Home 
Scanner is one of a new generation of scanners designed to track Motorola 
Type 1, Type 11 (such as Smartnet and Privacy Plug, GE/Ericsson EDACS), 
and hybrid analog trunking systems, which are extensively used in many 800 
MHz, 900 MHz and UHF communications 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 group of 
frequencies. Instead of selecting a specific frequency for a transmission, 
the 2-way radio user simply selects a talk group.  The trunking system 
automatically transmits the call on the first available frequency, and 
also sends a code that uniquely identifies that 2-way radio user's 
transmission on a different frequency called a data channel.

Since the trunking system might send individual 2-way radio user's calls
and response transmissions on different frequencies, it is difficult to 
listen to trunked communications using a regular scanner.  The PRO-2052 
monitors the data channel frequency sent with a 2-way radio user's 
transmission and instantly switches to an active frequency, so you can 
hear the call and response for that 2-way radio user and easily "follow" 
the conversation.

The scanner also lets you scan conventional transmissions, and is 
preprogrammed with service-search 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 51,000 exciting frequencies, 
including those used by police and fire departments, ambulance services, 
and amateur radio services, and you can change your selection at any time.

Features

Your scanner also has these special features:

          Flexible Operation - you can track both Motorola and GE/Ericsson 
                               trunking systems (used by most trunking 
                               communications systems today), letting you 
                               hear more calls than many standard trunking 
                               scanners.

       Frequency Coverage to - provides a wide range of frequencies you 
                     1.3 GHz   can listen to.

Twenty Channel-Storage Banks - lets you store 50 channels in each bank 
                               (1000 total channels, letting you group 
                               channels so you can more easily identify 
                               calls.

      NWR-SAME/Weather Alert - you can set the scanner to sound an alert 
                               when it receives NOAA's Specific Area 
                               Message Encoding (SAME) coded weather 
                               emergency signal, providing more complete 
                               information about weather conditions in 
                               your immediate area and letting you avoid 
                               hearing alerts for geographical areas that 
                               do not interest you. 

          Remote PC Function - lets you control the PRO-2052 from your 
                               personal computer.

             Five Scan Lists - lets you store up to 50 IDs in each
                               tracking bank (up to a total of 1000).

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

                  Scan Delay - delays scanning for about 2 seconds before 
                               moving to another channel in conventional 
                               mode, so you can hear more replies that are 
                               made on the same channel. In trunk scanning
                               mode, it delays for about 5 seconds before
                               moving to another ID.

           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 
                               (10 in all).  As the scanner scans a bank, 
                               it checks the bank's priority channel every 
                               2 seconds so you don't miss transmissions 
                               on that channel.

   Five Service-Search Banks - lets you search preset frequencies in 
                               separate public service, police, fire/ 
                               emergency, aircraft, and weather banks to 
                               make it easy to locate specific types of 
                               calls. 

   HyperSearch and HyperScan - lets you set the scanner to search at up to 
                               300 steps per second (in frequency bands 
                               with 5 kHz steps) and scan at up to 50 
                               channels per second, to help you quickly 
                               find interesting broadcasts, (The normal 
                               search speed is 100 steps per second).
 
            Data Signal Skip - lets you set the scanner to skip non 
                               modulated or data signals during scanning 
                               and searches.  This lets the scanner avoid 
                               non-voice signals, making a scan or search 
                               faster.

               Manual Access - you can directly access any stored channel 
                               by entering that channel's number. 

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

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

Supplied Telescoping Antenna - provides good reception of strong local 
                               signals.

   External Antenna Terminal - lets you connect an external antenna with a 
                               BNC connector to the scanner for improved 
                               reception of distant/weaker signals.

               Memory Backup - keeps the channel frequencies stored in 
                               memory in the event AC power goes out.

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

     Duplicate Channel alert - warns you when the frequency you are 
                               storing already exists in memory.

      Disconnect Tone Detect - the scanner automatically tunes to the 
                               trunking data channel when it receives a 
                               disconnect transmission.  You can turn this 
                               feature off to continuously monitor a 
                               channel with a weak transmission during 
                               disconnected conversations.

FCC Notice

Your scanner might cause radio or TV 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 the following methods to eliminate the 
interference:

  Move your scanner away from the receiver.

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

  Contact your local RadioShack store for help.

Note:  Mobile use of this scanner is unlawful or requires a permit in some 
       areas.  Check the laws in your area.

Scanning Legally

Your scanner covers a 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 is designed to prevent reception of illegal transmissions, in 
compliance with the law which requires that scanners be manufactured in 
such a way 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.
