INTRODUCTION

Your new RadioShack PRO-2052 1000-Channel Dual Trunking TrunkTracker Home Scanner is one of a new generation of scann ers designed to track Motorola Type I, Type II (such as Smartnet and Privacy Plus), GE/Ericsson EDACS, and hy brid analog trunking systems, which are extensively used in many 800 MHz, 900 MHz and UHF communi cation systems.

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

Since the trunking system might send individual 2-way radi o user’s c alls 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 frequ ency sent with a 2-way radio user’s tran smissi on and instantly switches to an active frequency, so you can he ar 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 conven ience. By pre ssing 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 di rect 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

both Motorola and GE/Erics son trunking systems (used by most trunking communications systems today), letting you hear more calls than many standard trunking scanners.

Frequency Coverage to 1.3 GHz

provides a wide ran ge of frequencies you can listen to.

Twenty Channel-Storage Banks

let 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 En codi ng (S AM E) co d ed weather emergency sig nal, providing more complete information about weather conditions in yo ur 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 pe rsonal computer.

Five Scan Lists

— let you store up to 50 IDs in each tracki ng 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 bef ore m oving to an other 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 pro-

gram one channel in each bank (10 in

all). As the scanner scans a bank, it checks the bank’s pr iority channel e very 2 seconds so you don't miss transmissions on that channel.

Five Service-Search Banks

— let you search preset frequen cies in separate public se rvice, police, fire/emer gency, aircraft, and weather b anks, to make it easy t o loca t e sp e cif i c types of calls.

HyperSearch and HyperScan



— let you set the scanner to search at up to 300 steps per se cond (i n frequen cy bands with 5 kHz steps) and scan at up to 50 channel s per se cond, to help you quickly find interesting broadcasts. (The normal search speed is 100 steps per second).

Data Signa l Skip

— lets you set the scanner to skip non-modulated or data signals during scanning and searches. This lets the scanner avoid non-voi ce signals, making a sc an or sea rch 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.

20-432.fm Page 4 Friday, July 14, 2000 11:30 AM

Supplied Telescoping Antenna

— provides good reception of strong local signals.

External Antenna Terminal

— lets you connect an external ante nna 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 to ne when yo u perform an operation correctly, and an error tone if you make an error.

Duplicate Channel Alert

— warns you when the frequency you are stor ing already exists in memory.

Disconnect Tone Detect

— the scanner automatically tunes to th e tr un ki ng data channel when it receives a disconnect transmission. You can turn this feature off to conti nuo usl y mon ito r a channel with a weak transmission during disconnected conversations.

Your PRO-2052 scanner can receive these bands:

FCC NOTICE

Your scanner m ight cause radio or TV interference even when it is op erating 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 scann er a w ay from the receiver.

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

• Contact your local RadioShack store for help.

Note:

Mobile use of this scanner is unlawful or requires a per mit in some areas. Check the laws in your area.

SCANNING LEGALLY

Your scanner covers frequencies used by many different group s including police and fire departments, ambulance services, government agencie s, private companies, a mateur rad io ser vices, military operations, pager services, and wireline (telephone and telegraph) service pro vide rs. It is leg al to listen to almo st 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 th e Electro nic Comm unications 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 par ty 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 man ufactured in such a way as to not be easily modifiable to pick up those transmi ssions. Do not open your scanner's case to make any modifications that c ould 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.

PREPARATION

This scanner is des igned primarily for use in the home as a base station. You can place it on a desk, she lf, or table.

Your scanner’s front feet fold up or down. Adjust them to give you the best view of the display.

Your scanner’s display is protected during shipment by a piece of film. Peel off this film before you use the scanner.

The scanner’s sensitivity depends on the antenna’s leng th an d v ariou s e nv ironmental condition s. For the best reception of the transm issions you want to hear, adjust the antenna’s length.

CONNECTING AN ANTENNA

Connecting the Supplied Antenna

You must install an antenna before you can operate the scanner.

The supplied telescoping antenna helps your scann er receive strong local signals. To install the antenna, thread it clockwise into the hole on the scanner’s top.

Connecting an Outdoor Antenna

Instead of the supplied antenna, you can connect an outdoor base-station or mobile antenna (not supplied) to your scanner using a BNC conn ector. Your local RadioShack store sells a variety of antennas. Choose the one that best meets your needs.

When deciding on a mobile or basestation antenna an d its location, consider these points:

20-432.fm Page 9 Friday, July 14, 2000 11:30 AM

• The antenna should be as hi gh a s possible on the vehicle or building.

• The antenna and its cable shoul d be as far as possible from sources of electrical noise (appliances, other radios, etc.).

• The antenna should be vertical for the best performance.

To connect an optional base-station or mobile antenna, first re move the supplied antenna from the scanner. Always use 50-ohm co axial cable, such as RG-58 or RG-8, to connect the base-station or mobile antenna. For lengths over 50 feet, use RG-8 lowloss dielectric co axial cable. If the antenna cable’s connec tor does not fit i n

back of the scanner.

Cautions:

• Do not run the cable over sharp edges or mov ing parts that might damage it.

• Do not run the cable next to power cables or other antenna cables.

Warning:

Use extreme caution when you install or remove an outdoor antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. DO NOT attempt to do so yourself.

CONNECTING POWER

Using AC Power

The scanner’s supplied AC adapter lets you power the scanner from a standard AC ou tlet. To conne ct po wer to the scanner, insert the AC adapter’s barrel plug into the back of the scanner, then plug the AC adapter into a standard AC outlet.

UNDERSTANDING BANKS

Channel Storage Banks

To make it easier to identify and select the channels you want to listen to, channels are divi ded into 20 banks of 50 channels each. Use each channelstorage bank to group frequencies, such as those used by th e police department, fire department, am bulance services, or aircraft (see “Guide to the Action Bands” on Page 56).

For example, the police department might use four frequencies, one for each side of town. You could program the police frequencies starting with Channel 1 (the first channel in ba nk 1) and program the fire department frequencies starting with Channel 51 (the first channel in bank 2).

Service Banks

The scanner is preprogrammed with the frequencies allocated by public safety, police, fire/emergen cy, airc raft, and weather services. This is handy for quickly finding active frequencies instead of searching th rough an en tire band (see “Searchin g Service Banks” on Page 19).

UNDERSTANDING TRUNKING

In the past, groups that b roadcast frequently, such as police departments, were restricted to tr ansmitting on just a few frequencies. This resulted in heavy traffic and often r equired 2-way radio users to wait for a specific frequency to clear before transmitting.

Trunked systems allow more groups of 2-way radio users to use fewer frequencies. Instead of selecting a specific frequency to transmit on, a trunked system c hooses on e of sev er al frequencies when the 2-way radio user presses PTT (push to talk). The system automatically transmits the call on that frequency, and also se nds a code that ide ntifies that 2-wa y radio user’s transmission on a data channel.

You can set this scanner to monitor the data channel frequency, so you can hear both the call and response transmissions for that 2-way radio user and therefore fo llow the conversation. (You canno t listen to the data channel itself in trunking mode.)
