FEATURES
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 sim ply selec ts a talk g r ou p. The t run ki ng system automatically transmits the call on the first avail­able frequency, and also sen ds (on a dif ferent frequen­cy called a data channel) a code that uniquely identifies that transmission.
Since the trun king sys tem m ight send a c all an d its re ­sponse on di fferent fr eq ue ncies, it is difficult to l ist e n t o trunked co mmunicat ions using a reg ular scanne r. The PRO-91 l ets you select and mo nitor the data channe l frequency se nt w it h a 2-w ay rad io transmission, so you can he ar the ca ll and res ponse for that u se r 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 complicat ed programming.
This sc an n er gives y o u d ir ec t ac c es s to ov er 30 ,00 0 e x­citing 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 th ese special features:
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 — delay s scanning for about 2 seconds before moving to another channel, so you can hear mor e replies that are made on the same chan­nel.
Lock-Out Functi on — lets you set your scanner to sk ip 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.
Five Service Banks — frequencies are preset in sepa­rate police (fire/emergency), aircraft, ham, marine, and weather banks, to make it easy to locate specific types of calls.
Hypersearch — lets you set the scanner to search at up to 300 steps per second. The normal search speed is 100 steps per second.
Hyperscan— the scanner automatically scans up to 50 channels per second in frequency bands with 5 kHz steps, to help you quickly find interesting broadcasts.
Key Lock — lets you lock the scanner's keys to help prevent accidental changes to the scanner's program­ming.
Data Signal Skip — lets you set the scanner to skip non-modulated or data signals (such as fax or modem transmissions) during searches. This lets the scanner avoid non-voice signals, making a search faster.
Manual Access — lets you directly access any channel. Liquid-Crystal Display — makes it easy to view and
change programming information. Display Backlight — makes the scanner easy to read
in low-light si tuations.

SCANNING LEGALLY
Your scanner covers frequencies used by many differ­ent groups includin g police and fire depar tmen ts, 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 f or intentionally listen ing to, using, or divulg­ing the contents of such a transmission unless you have the consent of a party to the communication (un­less such activ ity is otherwise ill egal).
This scanner is designed to prevent reception of illegal transmissions, in compliance with the law which re-

PREPARATION
POWER SOURCES
You can power your scann er fr om any of thre e sou rces:
• Internal batteries (not suppli ed)
• Standard AC power (usin g an opti onal AC adapt er)
• Vehicle battery power (using an optional DC adapter)
Using Internal Batteries
You can power your scanner using four AA batteries. For the longest operation and best performance, we recommend alkaline batteries (such as Cat. No. 23-
552).
You can also use four rechargeable nickel-cadmium batteries (Cat. No. 23-125). Before you use nickel-cad­mium batteries, you must charge them (see “Charging Nick el-Ca d mium Batt eries ” on P age 11).
Follow these steps to install batteries.

4. Install two batteries in the compartment and two in the cover as indicated by the polarity symbols (+ and –) marked inside those locations.
Cautions:
• Use only fresh bat teries of the required size and
recommended type.
• Always remove old or weak batteries. Batteries
can leak chemicals that destroy electronic cir­cuits.
• Do not mix old and new batteries, different
types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of dif­ferent capacit ies.
5. Replace the cover.

20-521 .fm Page 12 We dnesday, August 4, 1999 3:32 PM
Important: At the end of a rechargeable battery’s use­ful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that might be available are: municipal curb-side collection, drop-off boxes at retailers such as your local Ra­dioShack store, recycling collection centers, and mail­back programs.
Using AC Power
You can power the scanner from a standard AC outlet using an optional AC adapter (such as Cat. No. 273-
1665). Warning: Do not use an AC adapter’s polarized plug
with an extension cord, receptacle, or other outlet un­less the blades can be fully inserted to prevent blade exposure.
Cautions:
• The recommended AC adapter supplies 9 volts and delivers at least 300 milliamps. It has a barrel plug with a c enter negative tip that correctly fits the scanner’s
POWER
jack. Using an adapter that does not meet these specifications could dam age the scanner or the adapter.
• To protect your scanner and AC adapter, always plug the adapter into the scanner before you plug it into the AC outlet, and always unplug the adapter from the AC outlet before you unplug it from the scanner.
• If batteries are installed, make sure the battery switch inside the battery compartment is set to the correct position (see “Using Internal Batteries” on Page 9).

Using Vehicle Battery Power
You can power the scanner from your vehicle’s battery power using an optional DC adapter such as Cat. No. 270-1560.
Cautions:
• The recommended DC adapter supplies 9 volts and delivers at least 300 milliamps. It has a barrel plug with a center negati ve tip that correctly fits the scanner’s
POWER
jack. Using an ad apter that does not meet these specifications could damage the scanner or t he adapter.
• To protect your vehicle’s electrical system, always plug the adapter into the scanner before you plug it into your vehicle’s ci garette-lighter socket. Alwa ys unplug the adapter from the vehicle’s cigarette­lighter socket before you unplug it from the scan­ner.
• If batteries are installed, make sure the battery switch inside the battery compartment is set to the correct position (see “Using Internal Batteries” on Page 9).

CONNECTING THE ANTENNA
Follow these st eps to attach the supplied flexible anten­na to the connector on the top of your scanner.
1. Align the slots around the antenna’s c onnector with the tabs on the scanner’s BNC connector.
2. Slide the antenna’s connector down over the scan­ner’s connector and rotate the antenna connector’s outer ring clockwise until it locks into place.
Connecting an Optional Antenna
The scanner’s BNC connector makes it easy to connect a variety of optional antennas (such as an external mo­bile antenna or outdoor base station antenna). Your lo­cal RadioShack sto re sel ls a variety of antennas.
Note:
Always use 50-ohm coaxial cable, such as RG­58 or RG-8, to connect an outdoor antenna. If the dis­tance from the scanner to the antenna is over 50 feet, use RG-8 low-loss dielectric coax ial cable. If your an­tenna’s cable does not have a BNC connector, your lo­cal RadioShack store carries a variety of BNC adapters.
15
20-521 .fm Page 16 We dnesday, August 4, 1999 3:32 PM
CONNECTING AN EARPHONE/ HEADPHONES
For private listening, you can plug an earphone or mono headphones (such as Cat. No. 33-178 or 20-
210) into the jack on top of your scanner. This auto­matically disconnects the internal spea ker.
Listening Safely
To protect your hearing, follow these guidelines when you use an earphone or headphones.
• Do not listen at extremely high volume levels. Extended high-volume listening can lead to per­manent hearing loss .
• Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.
• Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a vol­ume level that does not cause discomfort might still damage your hearing.
Traffic Safety
Do not use an earphone or headphones with your scanner when operating a motor vehicle in or near traf­fic. Doing so can create a traffi c hazard and could be il­legal in some areas.
If you use an earphone or headphones with your scan­ner, be very careful. Do not listen to a continuous broadcast. Even though some earphones/headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

UNDERSTANDING BANKS
Service Banks
The scanner is preprogrammed wi th all the fr equencies allocated to the weather, ham, marine, air craft, and po­lice (fire/emergency) services. This is handy for quickly finding active frequencies instead of doing a limit search (see “Servi ce Bank Search” on Page 28).
Channel Storage Banks
To make it easier to identify and select the channels you want to listen to, channels are divided into 5 banks of 30 channels each. Use each channel-storage bank to group frequencies, such as those for the police de­partment, fire department, ambulance services, or air­craft (see “Guide to t he Acti on Bands” on Page 58).
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 bank 1), and program the fire de­partment frequencies starting with Channel 31 (the first channel in bank 2).
22
20-521 .fm Page 23 We dnesday, August 4, 1999 3:32 PM
Monitor Memories

TRUNK TRACKING
Your scanner is designed t o track transmissions o n M o­torola Type I, Type II, and hybrid analog trunking sys­tems, which are extensively used in 800 MHz communications. Remember these important points when tracking transmissions:
• Your scanner monitors Type II systems by default. However, you can change this if the system in your area is different (see “Types of Trunking Systems” below and “Scanning Type I and Hybrid Trunked Systems” on Page 50 for more information).
• Your scanner cannot track transmissions on non­Motorola trunking systems.
• Your scanner cannot track an 800 MHz trunked system and scan conventional frequencies at the same time.
• The frequencies for many of the 800 MHz public safety systems are listed in the separate “National Public Safety Trunked System Frequency Guide” included with your PRO-91.
TYPES OF TRUNKING SYSTEMS
Your trunk trac king scanner can monitor two basic types of systems — specific frequency to transmit on, a trunked system chooses one of several frequenc ies in a 2-wa y radio us­er’s talk group when that user presses PTT (push to talk). Thus, trunking systems allocate a few frequencies among many different users, but the way Type I and Type II sy stems do this is sli ghtly dif ferent. One impo r­tant distinction between these systems is the amount of data transmitted by each radio when its push-to-talk (PTT) button is pressed. In a Type I system, the radio’s ID and its c urrent affilia tion (the trunk syste m it be longs to) are both transmitted. In a Type II s ystem, only the ra­dio’s ID is tran sm itted.
Why the difference? In Type I systems, each radio in the trunk group individually transmits its own affiliation, while the trunk system maintains a database that deter­mines each radio's affiliation(s) in Type II systems.
Another difference between the systems is that Type I systems are arranged in a fleet-subfleet hierarchy. For example, it is possible for a city using a Type I system to designate 4 fleets, each with 8 subfleets.
Type I
and
Type II
. Instea d o f sel ecti ng a
39
20-521 .fm Page 40 We dnesday, August 4, 1999 3:32 PM
The fleets might be the police department, the fire de­partment, utilities, and city administration. The police might decide to further divide its fleet into subfleets such as dispatch, tactical operations, detectives, north, south, east and west side patrols, and supervisors. All the available police radios would then be assigned to one of the police subfleets, letting the police centralize their communications and control the type of users on a single system. Determining the exact fleet-subfleet hierarchy for a particular area is referred to as fleet map programming.
The disadvantage of a Type I system is that the brief burst of data sent when a user transmits must contain the radio’s ID and its fleet and subfleet. This is three times the amount of data a Type II system radio sends. Since the data capaci ty of Type I syst ems is limi ted and the amount of data increases with each user, Type I systems usually accommodate fewer users than Type II systems. Nevertheless, Type I systems are still in use.
There are also of both Type I and Type II. Your scanner defaults to monitor Type II systems, but you can change to Type I or a hybrid of Type I and Type II systems by selecting a preprogrammed fleet map or creating a custom fleet map for your area (see “Scanning Type I and Hybrid Trunked Systems” on Page50).
You do not need to determine the fleet-subfleet hierar­chy for Type II systems unless you are tracking hybrid systems that contain both Type I and Type II systems.

Your scanner’s squelch setting is automatically adjust­ed during trunk tracking, which means it is not neces­sary to manually adjust squelch while tracking trunked transmissions. However, the squelch setting can affect how fast your scanner acquires the data channel, and, in some instances, can pr event your scanner from ac­quiring the data channel at all.

• You can use any of your scanner’s banks as either a trunk tracking bank or conventional scanning bank, but you cannot mix the two.
• The scanner only scans one trunked system at a time. Although you can store frequencies for more than one trunked system in one of your scanner’s banks, the scanner only scans the frequencies associated with the first data channel it finds.

CHANNEL ACTIVITY BARS
Your scanner has 20 channel activity indicators (bars) which show the activity taking place on a trunked sys­tem. You can see how many frequencies are being used and generally monitor how much communication traffic is occurring.
Each frequency you store in a trunking bank has a cor­responding activity bar. However, since there are only 20 bars, but you can store up to 30 frequencies, some bars might indicate more than one frequency if the trunked system you are scanning has more than 20 channels.
• The bar that remains on steadily even when there are no current transmissions represents the fre­quency being used as the dat a channel.
• The bar that flashes when an ID appears repre­sents the frequency being used by the radio to transmit what you are currently hearin g.
• If a bar turns on but you do not hear a conversa­tion, the channel is probably being used for a tele­phone interconnect call or a private call, or the bar might be a locked-out ID. Your scanner does not monitor these types of calls.
• If the scanner is holding on an ID which is not active, the other activity bars turn on and off as other groups use the system.

SCAN LISTS
When you program trunked frequencies into a bank (see “Storing Trunked Frequencies” on Page 41), your scanner sets up 5 scan lists into which you can store your favorite IDs. Each list can contai n up to 10 IDs, so you can store a total of 50 IDs for each trunk tracking bank (250 IDs if you use all banks as trunking banks!). Scan lists hel p you organize tru nking system users into categories. For example, you might use List 1 for police IDs, List 2 for fire department IDs, List 3 for emergency medical service IDs, and so on. Once IDs are stored in lists, you can scan them like you scan conventional channels. You can pr ogram IDs into scan lists manual­ly, during a search, or automatically.
Manually Storing IDs into Scan Lists

SCANNING TYPE I AND HYBRID TRUNKED SYSTEMS
Your PRO-91 is set to sc an Type II user IDs by default. When you scan trunked frequencies, each Type II user ID you see appears as an even number without a dash (such as 2160). Your PRO-91 can also scan Type I trunked systems. Each Type I ID appear s as a three- or four-digit number, followed by a hyphen, followed by a one- or two-digit number (such as 200-14). If you no­tice a mix of odd- and even-user IDs (such as 6477, 2160, 6481, 6144, and 1167), then you are probably monitoring either a Type I or hybrid (a combination of Type I and Type II user IDs) system (see “Types of Trunking Systems” on Page 39).
You might also notice that you are missing responses when you hold on an active ID. Unli ke Type II systems, Type I and hybrid systems require a fleet map that sets specific fleet-subfleet parameters. I t is easy to select a fleet map to scan; what is not always easy is selecting or programm ing a map that is b eing used in your partic­ular area.

When a Type I system is designed, the address infor­mation for all its user IDs is divided into 8 equal-size blocks, numbered 0–7, and each block is assigned a size code. When you set up your scanner to track a Type I system, you must choose a size code for each block. When you have chosen a size code for all 8 blocks, you will have duplicated the
fleet m ap
for the system you are tracking. If you have chosen correctly, you will be able to track transmissions in that system.
Each size code defines the number of fleets, subfleets, and IDs each block has. For example, you can see in the following table that a size code of S-4 has one fleet, which is divided into 16 s eparate subfleets, and it has a total of 512 individual IDs.

Each ID in the block is unique. The left- mo st di git is the block number in the ID. The next two digits identify which fleet is active, and the last digit(s) (after the hy­phen) identifies the subfleet.

The size codes selected by a Type I system designer depend on the specific needs of the system's users. Some organizations might want many subfleets with only a few radios each, while another organization might want onl y a few subfleets, with m any radios each. To scan Type I systems, you must select or program a fleet map with the same size code assignments as the trunked system. If you do this accurately, you will track all the fleet and subfleet combinations used by the sys­tem. In other wo rds, y ou will hea r comp lete comm uni­cations whi le monitoring a trunked system.
Note: Preset fleet maps might be available at

.
If you do not al ready know the si ze codes used, you wi ll have to guess them. But si nce you do not have to figure out all the blocks at once, this is not as hard as it seems. Select a size code for a block, then press
SRC
Now listen to the communications. I f you decide you are receiving most of the replies to the conversations with IDs assigned to the block you just programmed, then you have probably selected the right size code and can work on the next block of the map.
.
There are 16 preset fleet maps to choos e from, and it is best to start with these when setting up a Type I or hy­brid trunk tracking bank. If none of the following preset fleet maps allow you to follow complete conversations, then you probably need to program your own fleet map (see “Programming a Fleet Map” on Page 51).

FREQUENCY CONVERSION
The tuning location of a station can be expressed in frequency (kHz or MHz) or in wavelength (meters). The following information can help you make the necessary conversions.
1 MHz (million) = 1,000 kHz (thousand)
To convert MHz to kHz, multiply the number of mega­hertz by 1,000:
9.62 (MHz) x 1000 = 9620 kHz
To convert from kHz to MHz, divide the number of kilo­hertz by 1,000:
2780 (kHz) ÷ 1000 = 2.780 MHz
To convert MHz to m eters, divide 300 by the number of megahertz:
300 ÷ 7.1 MHz = 42.25 meters

CARE AND MAINTENANCE
Your RadioShack PRO-91 150-Channel Handheld Trunking Scanner is an e xam ple of super ior design and craftsmanship. The following suggestions will help you care for your scanner so you can enjoy it for years.
Keep the scanner dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits.
Use only batteries of the recommended size and type. Always remove old and weak batteries. They can leak chemicals that destroy electronic circuits.
Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can cause the scanner to work improperly.
Use and store the scanner only i n normal temperature environments. Temperature extremes can shorten the life of electron­ic devices, damage batteries, and distort or melt plasti c parts.
Keep the scanner away from dust and dirt, which can cause premature wear of parts.
Wipe the scanner with a damp cloth oc­casionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents t o clean the scan­ner.
Modifying or tampering with the scanne r’ s internal com­ponents can cause a malfunction, invalidate your scan­ner’s warranty and void your FCC authorization to operate it. If your scanner is not operating as it should, take it to your local RadioShack stor e for assistance.
