FEATURES

Your RadioShack PRO-94 1000-Channel Handheld Trunking Scanner is one of a new generation of scanners designed to track Motorola Type I, Type II, hybrid analog systems, (such as Smartnet and Privacy Plus) plus GE/Ericsson EDACS. Those systems are extensively used in many 800 MHz, 900 MHz, and UHF communication systems.

Trunking communications systems let a large group of 2way radio users (or even different groups of 2-way radio users) efficiently use a set 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-94 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 it 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 37,000 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:

Triple-Conversion Circuitry

— virtually eliminates any interference from IF (intermediate frequency) images, so you hear only the selected frequency.

20-524.fm Page 3 Tuesday, August 31, 1999 3:55 PM

20 Channel-Storage Banks

— you can store up to 50 channels in each of 10 different banks, in two separate groups, for a total of 1000 channels, so you can more easily identify calls.

Five Scan Lists

— you can store up to 50 trunking talk

group IDs in each trunk scanning bank.

NWR-SAME Circuitry

— lets you listen to coded weather emergency information using Specific Area Message Encoding.

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 talk group IDs when tracking trunked systems.

Priority Channels

— lets you program one channel in each bank (20 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 in frequency bands with 5 kHz steps, compared to the normal search speed of 100 steps per second.

Hyperscan

— the scanner automatically scans up to 50 channels per second 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.

20-524.fm Page 4 Tuesday, August 31, 1999 3:55 PM

Disconnect Tone Detect

— the scanner automatically tunes to the trunking data channel when it receives a disconnect transmission. You can turn this off, so you can continuously monitor a channel with a weak transmission where conversations are often disconnected.

Manual Access

— lets you directly access any chan-

nel.

Liquid-Crystal Display

— makes it easy to view and

change programming information.

Display Backlight

— makes the scanner easy to read

in low-light situations.

Flexible Antenna with BNC Connector

— provides adequate reception in strong signal areas and is designed to help prevent antenna breakage. Or, you can connect an external antenna for better reception.

Monitor Memories

— let you temporarily store up to

10 frequencies or talk group IDs.

Memory Backup

— keeps the frequencies stored in memory for an extended time if the PRO-94 loses power.

Three Power Options

— let you power the scanner using internal batteries, external AC power using an optional AC adapter/charger, or DC power using an optional DC cigarette-lighter power cable.

Key Confirmation Tones

— the scanner sounds a tone when you perform an operation correctly, and an error tone if you make an error.

Battery Save

— saves battery power when the scanner does not detect any transmissions for more than 5 seconds when a channel is manually selected.

Battery Low Alert

— warns you when battery power

gets low.

Weather Alert Indicator

— your scanner also func-

tions as a severe weather alert monitor.

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 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), as amended, 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).

20-524.fm Page 7 Tuesday, August 31, 1999 3:55 PM

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 coul d subject you to legal penalties.

We encourage responsible, legal scanner use.

15 seconds, replace all four batteries.

Caution:

Always dispose of old batteries promptly and

properly. Do not bury or burn them.

Using Rechargeable Batteries

You can also use four rechargeable batteries. Before you use nickel-cadmium or nickel-metal hydride batteries, you must charge them .

The scanner has a built-in circuit that lets you recharg e Ni-Cd and Ni-MH batteries while they are in the sca nner. To charge the batteries, set

NI-CD

, install the batteries in the scanner, and

NI-CD

connect an external AC or DC adapter to the scanner’s

POWER

jack (see “Using AC Power” on Page 13 or “Us-

ing Vehicle Battery Power” on Page 14).

Warning:

Do not connect either adapter to the scanner if non-rechargeable batteries (such as alkaline batteries) are installed in the scanner and

NI-CD

is set to

or if you are unsure of the switch’s position. Non-rechargeable batteries will get hot and can even explode if you try to recharge them.

Before you use Ni-Cd or Ni-MH batteries for the first time, charge them at least 24 hours to bring them to a full charge.

ALKALINE JACK

Discharged batteries take about 10 to 18 hours to fully recharge. If you use the scanner while the batteries are charging, charging takes longer.

Notes:

• Nickel-cadmium batteries last longer and deliver more power if you occasionally let them fully discharge. To do this, simply use the scanner until it beeps every 15 seconds and

BATT.Lo

flashes.

• To prevent damage to nickel-cadmium batteries, never charge them in an area where the temperature is above 113°F (40°C) or below 40°F (4°C).

20-524.fm Page 13 Tuesday, August 31, 1999 3:55 PM

Important:

This scanner can use nickel-cadmium rechargeable batteries. At the end of a nickel-cadmium 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 or call 1-800-843-7422. Some options that might be available are: municipal curbside collection, drop-off boxes at retailers such as your local RadioShack store, recycling collection centers, and mail-back programs

USING AC POWER

You can power the PRO-94 using an 9V, 300 mA AC adapter and a size H Adaptaplug® (neither supplied). Both are available at your local RadioShack store.

Cautions:

You must use a Class 2 power source that supplies 9V DC and delivers at least

300 mA. Its center tip must be set to neg-

ative and its plug must fit the PRO-94's

300MA

jack. Using an adapter that does not meet these specifications could damage the PRO-94 or the adapter.

• Always connect the AC adapter to the PRO-94 before you connect it to AC power. When you finish, disconnect the adapter from AC power before you disconnect it from the PRO-94.

20-524.fm Page 16 Tuesday, August 31, 1999 3:55 PM

CONNECTING THE ANTENNA

To attach the supplied flexible antenna to the connector on the top of your scanner, align the slots around the antenna’s connector with the tabs on the scanner’s BNC connector. Then 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, including an external mobile antenna or outdoor base station an tenna. Your local RadioShack store sells a wide selection of antennas.

Note:

Always use 50-ohm, RG-58, or RG-8, coaxial cable to connect an outdoor antenna. If the antenna is over 50 feet from the scanner, use RG-8 low-loss dielectric coaxial cable. If your antenna’s cable does not have a BNC connector, your local RadioShack store carries a variety of BNC adapters.

20-524.fm Page 17 Tuesday, August 31, 1999 3:55 PM

CONNECTING AN EARPHONE/ HEADPHONE

For private listening, you can plug an optional earphone or mono headphones into the jack on top of your scanner. This automatically disconnects the internal speaker.

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 traffic 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.

20-524.fm Page 18 Tuesday, August 31, 1999 3:55 PM

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an optional extension speaker, positioned in the right place, might provide mor e com fortable listening. Plug the speaker cable’s mm) mini-plug into your scanner’s jack. Your local RadioShack store carries a selection of suitable speakers.

UNDERSTANDING BANKS

Service Banks

The scanner is preprogrammed with all the frequencies allocated to the weather, ham, marine, aircraft, and police (fire/emergency) services. This helps you quickly find active frequencies instead of doing a limit search (see “Service Bank Search” on Page 29).

Channel Storage Banks

To make it easier to identify and select the channels you want to listen to, all the channels are divided into main bank groups A and B. Each main bank group has 10 banks of 50 channels. Use each channel-storage bank to group frequencies, such as those for the police department, fire department, ambulance services, or aircraft (see “Guide to the Action Bands” on Page 64).

For example, the police department might use four frequencies in your town while the fire department uses an additional four. You could program the four police frequencies starting with Channel 1 (the first channel in bank 1), and program the fire department frequencies starting with Channel 51 (the first channel in bank 2).

Monitor Memories

The scanner also has 10 temporary memory locations called monitor memories. Use these monitor memories to temporarily store frequencies when you search through an entire band (see “Searching For and Temporarily Storing Active Frequencies” on Page 27). You can then move a frequency to a channel for permanent storage. See “Moving a Frequency From a Monitor Memory to a Channel” on Page 31.

While you are searching frequencies, the 10 numb ers at the top of the display indicate the 10 monito r memo-

STORING KNOWN FREQUENCIES INTO CHANNELS

You can locate and store specific frequencies into channels for later use. To assist you in locating a desired frequency from the scanner’s wide range, consider using a frequency guide. Good references for active frequencies are the RadioShack “Police Call Guide including Fire and Emergency Services,” and “Official Aeronautical Frequency Directory.” We update these directories every year, so be sure to get a current copy.

To store trunked system frequencies, see “Stor-

ing Trunked Frequencies” on Page 43. Follow these steps to store frequencies into channels.

TRUNKING OPERATION

The PRO-94 scanner tracks transmissions that use the Motorola Type I, Type II, hybrid, and, Ericsson EDACS analog trunking systems. Remember these important points when tracking transmissions:

• Your scanner cannot scan trunked system and conventional frequencies at the same time.

• The frequencies for many of the 800 MHz, 900 MHz, and EDACS public safety systems are listed in the separate “National Public Safety Trunked System Frequency Guide” included with your PRO-94.

TYPES OF TRUNKING SYSTEMS

This trunking scanner monitors two basic types of systems — the Motorola Type I/Type II or hybrid System, and the Ericsson EDACS System. Instead of selecting a specific frequency to transmit on, a trunked system chooses one of several frequencies in a 2-way radio user’s talk group when that user presses their PTT (push to talk) control. Thus, trunking systems, in general, allocate a few frequencies among many different users. Motorola Type I and Type II systems achieve the same thing in a slightly different way. One importan t distinct ion between these systems is the amount of data transmitted by each radio when the operator pushes the PTT control. A Type I system, transmits the radio’s ID and its current affiliation or the trunk system to which it belongs. A Type II system only transmits the radio’s ID.

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 four fleets, each with eight subfleets.

20-524.fm Page 42 Tuesday, August 31, 1999 3:55 PM

The police department, fire department, utilities group, and city administration could each be a separate fleet. 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, le tting 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

fleet map programming

to as 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, its fleet information, and the subfleet information as well. This is three times the amount of data a Type II system radio sends. Since the data capacity of Type I systems is limited and the total 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.

hybrid

There are also of Type I and Type II. Your scanner is preset 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 Page 55).

SETTING SQUELCH FOR THE TRUNKING MODE

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

Turning the Status Bit Ignore (S-bit) On or Off

You can set how your scanner works with (also called S-bits), letting you control how the scanner interprets and displays talkgroup IDs.

The last four bits of a Motorola Type II talkgroup ID (a binary 16-bit code) are the status bits. In some systems, status bits identify special situations (such as an emergency status).

Your scanner is preset to assume that the status bits in a talkgroup ID are set to 0 and ignores them. For example, when the scanner receives the talkgroup ID 010111001110

0000

and converts the first 12 bits of the ID to 23776 (the talkgroup ID). However, since the status bit value is 3 (0011 converted to decimal equals 3), the ID is actually 23779.

If you are scanning a Motorola Type I system and do not have a fleet map for that system, you might have to turn off status bit ignore in order to determine the proper fleet map.

Locking Out Talk Group IDs

Many municipal and commercial services use trunk systems to transmit signals from such devices as water meter transmitters, door alarms, and traffic signals. Some signals are encrypted, as well, and most a re not voice signals. Since all these are assigned IDs just like other users, you may want to lock out reception of these ID signals. You can lock out up to 100 IDs at one time.

Note:

If you lock out an ID while searching, it is also locked out of the scan list(s). See “Using Talk Group ID Lists” on Page 52.

CHANNEL ACTIVITY BARS

Your scanner displays up to 20 channel activity bars for the stored frequencies in a bank. Thes e bars indicate the activity taking place on a trunked system. By observing these bars, you can see how many frequencies are being used and generally monitor how much communication traffic occurs.

Each frequency you store in a trunking ban k has a corresponding activity bar. However, there are only 20 bars for a possible maximum of 50 frequencies. If the trunk system contains more than 20 frequencies, some bars will represent more than one frequency.

• If a bar appears steadily without any voice transmission, it represents the frequency in use as the data channel.

• If a bar appears and flashes when an ID appears, the bar represents the frequency being used by the trunk system transmitter.

• If a bar appears without any voice transmission, the channel is probably being used for a teleph one 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 being used, the other activity bars turn on and off as other groups use the system.

USING TALK GROUP ID LISTS

When you program trunked frequencies into a bank (see “Storing Trunked Frequencies” on Page 43), your scanner sets up 5 scan lists for that one bank in which you can store your favorite IDs. Each list can contain

20-524.fm Page 53 Tuesday, August 31, 1999 3:55 PM

up to 10 IDs, for a total of 50 IDs for each trunk scanning bank. If you use all the banks as trunking banks, you can store 1000 IDs.

Talk group ID lists help you to organize trunking 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 you store all the IDs in a list, you can scan them just as you scan conventional channels. You can program IDs into talk group ID lists manually, during a sear ch, or automatically.

SCANNING TYPE I AND HYBRID TRUNKED SYSTEMS

Your PRO-94 is preset to scan Type II system IDs. When you scan trunked frequencies, each Type II user ID you see appears as an even number without a dash (example 2160). Your PRO-94 can also scan Type I trunked systems. Each Type I ID appears as a three- or four-digit number, followed by a hyphen, followed by a one- or two-digit number (example 200-14).

If you notice a mix of odd- and even-user IDs (examples 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 with the S-Bit function turned off (see “Types of Trunking Systems” on Page 41 and “Turning the Status Bit Ignore (S-bit) On or Off” on Page 47).

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) × 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 meters, divide 300 by the number of megahertz:

300 ÷ 7.1 MHz = 42.25 meters

CARE AND MAINTENANCE

Your RadioShack PRO-94 1000-Channel Handheld Trunking Scanner is an example of superior 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 might contain minerals that can corrode the electronic circuits.

Use and store the scanner only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.

Keep the scanner away from dust and dirt, which can cause premature wear of parts.

Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can cause the scanner to work improperly.

Use only fresh batteries of the required size and recommended type. Batteries can leak chemicals that damage your scanner’s electronic parts.

Wipe the scanner with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the scanner.

Modifying or tampering with the scanner’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 store for assistance.
