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 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.
3
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 channel.
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 functions as a severe weather alert monitor.

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).
6
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 could subject you to legal penalties.
We encourage responsible, legal scanner use.

PREPARATION
You can power your scanner from any of three sources:
• internal batteries (not supplied)
• standard AC power (using an optional AC adapter)
• vehicle battery power (using an optional DC adapter)
USING INTERNAL BATTERIES
You can power your scanner using four alkaline, lithium, or rechargeable (Ni-Cd, or Ni-MH) AA batteries
(not supplied). For the longest operation and best performance, we recommend the selected batteries available from your local RadioShack store.
Using Non-Rechargeable Batteries
Follow these steps to install non-rechargeable batteries.
1. Turn VOLUME/OFF counterclockwise until it clicks to make sure the power is turned off.
2. Slide up and hold the tab on the back of the scanner, then pull up the battery compartment cover from the top edge.
10
20-524.fm Page 11 Tuesday, August 31, 1999 3:55 PM
3. Before you install alkaline or any other nonrechargeable batteries, use a pointed object such as a ballpoint pen to set ALKALINE JACK
NI-CD inside the compartment to ALKALINE .
Warning: Set ALKALINE to NI-CD for use only with nickel cadmium (Ni-Cd) or nickel metal hydride (Ni-MH) rechargeable batteries. Never attempt to recharge non-rechargeable batteries.
Non-rechargeable batteries can get hot or explode if you try to recharge them.
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 batteries 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 capacities.
5. Replace the cover, inserting the lower tabs first.
11
20-524.fm Page 12 Tuesday, August 31, 1999 3:55 PM
When
BATT.Lo
flashes and the scanner beeps every
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 recharge
Ni-Cd and Ni-MH batteries while they are in the scanner. To charge the batteries, set ALKALINE
NI-CD to NI-CD , install the batteries in the scanner, and connect an external AC or DC adapter to the scanner’s
POWER jack (see “Using AC Power” on Page 13 or “Using 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 ALKALINE JACK
NI-CD is set to NI-CD, 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.
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).
12
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

2 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 negative and its plug must fit the PRO-94's POWER 9V
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.
13
20-524.fm Page 14 Tuesday, August 31, 1999 3:55 PM
Follow these steps to use the PRO-94 on AC power.
1. Turn VOLUME/OFF counterclockwise until it clicks to make sure the power is turned off.
2. Insert the Adaptaplug into the adapter’s cord so it reads TIP –. Insert the Adaptaplug into the PRO-
94’s POWER 9V 300MA jack.
3. Plug the adapter into a standard AC outlet.
If rechargeable batteries are installed and ALKALINE
JACK NI-CD is set to NI-CD , the adapter powers the scanner and recharges the installed batteries at the same time.
USING VEHICLE BATTERY POWER
You can power the PRO-94 from a vehicle’s 12V power source (such as cigarette-lighter socket) using a 9V,
300-mA DC adapter and a size H Adaptaplug ® (neither supplied). Both are available at your local RadioShack store.
Cautions:
!
You must use a power source that supplies 9V DC and delivers at least 300 mA. Its center tip must be set to negative and its plug must fit the PRO-94's POWER 9V
300MA jack. Using an adapter that does not meet these specifications could damage the PRO-94 or the adapter.
• Always connect the DC adapter to the PRO-94 before you connect it to the power source. When you finish, disconnect the adapter from the power source before you disconnect it from the PRO-94.
14
20-524.fm Page 15 Tuesday, August 31, 1999 3:55 PM
• 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 10).
1. Turn VOLUME/OFF counterclockwise until it clicks to make sure the power is turned off.
2. If the adapter has a voltage switch, set the switch to 9V.
3. Insert the Adaptaplug into the adapter’s cord so it reads TIP –. Insert the Adaptaplug into the PRO-
94’s POWER 9V 300MA jack.
4. Plug the adapter’s barrel plug into your scanner’s
POWER 9V 300MA jack.
5. Plug the other end of the adapter into your vehicle’s cigarette-lighter socket.
If rechargeable batteries are installed and ALKALINE
is set to NI-CD , the adapter powers the scanner and recharges the installed batteries at the same time.
Note: If the scanner does not operate properly when you use a DC adapter, unplug the adapter from the cigarette-lighter socket and clean the socket to remove ashes and debris.
15
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 antenna. 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.
16
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.
17
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 more comfortable listening. Plug the speaker cable’s 1 /
8
-inch (3.5mm) mini-plug into your scanner’s jack. Your local
RadioShack store carries a selection of suitable speakers.
ATTACHING THE BELT CLIP
To make your scanner easier to carry when you are on the go, use the supplied belt clip. Use a Phillips screwdriver and the supplied screws to attach the clip to the scanner.

20-524.fm Page 19 Tuesday, August 31, 1999 3:55 PM
ABOUT YOUR SCANNER
We use a few simple terms in this manual to explain the features of the PRO-94. Familiarize yourself with these terms and the scanner’s features and you can put the scanner to work for you right away. Simply determine the type of communications you want to receive, then set the scanner to scan those communications.
The PRO-94 scans conventional frequencies and
trunked systems. For more information about trunked transmissions see “Trunking Operation” on Page 41.
A frequency, expressed in kHz or MHz, is the tuning location of a station. To find active frequencies, you use the search function or refer to a frequency reference such as the included Trunking Frequency Guide.
Besides searching within a selected frequency range, you can also search your scanner’s service banks.
Service banks are preset groups of frequencies categorized by the type of services that use those frequencies.
For example, many amateur radio frequencies are located in the HAM service bank.
When you search and find a desired frequency, you can store it into a programmable memory location called a
channel. Channels are grouped into channel-storage
banks. The PRO-94 has 500 channels in channel-storage bank A and another 500 in channel-storage bank
B. Each bank of 500 is divided into ten 50-channel sets.
You can scan the channel-storage banks to see if there is activity on the frequencies stored there.
Or, when you find a frequency, you can store it into a
temporary memory location called a monitor memory until you decide whether or not to move it to a channel.
Just keep in mind — you search frequencies and scan channels.

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 numbers at the top of the display indicate the 10 monitor memories.
MON
appears and the flashing number beside it indicates the currently active monitor memory.

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.
Note: To store trunked system frequencies, see “Storing Trunked Frequencies” on Page 43.
Follow these steps to store frequencies into channels.
1. Press MAN and hold down A/B (HOLD) for about 2 seconds to select either main bank group. Enter the channel number where you want to store a frequency, then press PROG . The channel number appears.
2. Use the number keys and • ( MON/CLR) to enter the frequency (including the decimal point) you want to store.
3. Press E ( SVC ) to store the frequency into the channel.
Notes:
• If you entered an invalid frequency in Step 2,
Error
appears and the scanner beeps three times. Enter a valid frequency.
• The scanner automatically rounds the entered number to the nearest valid frequency. For example, if you enter 151.473 (MHz), your scanner accepts it as 151.475.
• Press DELAY to pause scanning 2 seconds after the end of a transmission before scanning proceeds to the next channel (see “Delay” on
Page 33). The scanner stores this setting in the channel.
4. To program the next channel in sequence, press
PROG and repeat Steps 2 and 3.

SCANNING THE STORED
CHANNELS
To begin scanning channels, press SCAN . The scanner scans through all non-locked channels in the activated banks. (See “Locking Out Channels” on Page 34 and
“Turning Channel-Storage Banks On and Off” on
Page 33). When the scanner finds a transmission, it stops on it. When the transmission ends, the scanner resumes scanning.
Notes:
• If you have not stored frequencies into any channels, the scanner does not scan.
• If the scanner picks up unwanted partial, or very weak transmissions, turn SQUELCH clockwise to decrease the scanner’s sensitivity to these signals. To listen to a weak or distant station, turn
SQUELCH counterclockwise.
• To ensure proper scanning, adjust SQUELCH until the audio mutes.
• To scan in the trunk scanning mode, see “Trunking
Operation” on Page 41.
MANUALLY SELECTING A
CHANNEL
You can continuously monitor a single channel without scanning. This is useful if you hear an emergency broadcast on a channel and do not want to miss any details — even though there might be periods of silence
— or if you want to monitor a specific channel.
To manually select a channel, press MAN , enter the channel number then press MAN again .
Or, if while scanning, the radio stops at a channel you want to listen to, press MAN one time. (Repeatedly pressing MAN at this time causes the scanner to step through the channels.) Press SCAN to resume automatic scanning.

RECEIVING NWR-SAME AND
WEATHER ALERT SIGNALS
In 1994, the National Oceanic and Aerospace Administration (NOAA) began broadcasting alerts that include digitally encoded data. Specific Area Message Encoding (SAME) includes information which identifies the severity of the alert. The PRO-94 displays this data as codes corresponding to the levels of severity (L1, L2, and L3).
Turning On the SAME
Weather Alert Feature
1. Press SVC (E) and select the weather search mode. See “Service Bank Search” on Page 29.
2. Press ALT (DATA) . This mutes the audio until the scanner receives a SAME coded signal.
38
20-524.fm Page 39 Tuesday, August 31, 1999 3:55 PM
When the scanner receives a SAME coded signal,
ALERT
flashes and an associated “L” code (which indicates the severity of the alert) appears, as well. The scanner remains on the weather channel and the audio turns on so you can hear the weather broadcast.
The scanner displays one of the following codes to indicate the alert level.
L1
: Warning
L2
: Watch
L3
: Statement
-----
: Non-emergency
In addition to weather alerts, the scanner also receives test and other event information. See “NWR-SAME
Code Detection Tests” on Page 40.
SAME Signal Detection Updating
When the scanner receives a SAME-coded signal, it retains information about the most recent alert until you turn off the power. Once the scanner detects an alert code,
ALERT
flashes. To verify the specific alert level
(L1, L2, or L3) press SVC (E) to select the weather search mode. Press ALT (DATA) to clear the alert.
39
20-524.fm Page 40 Tuesday, August 31, 1999 3:55 PM
NWR-SAME Alert Tone Test
To hear and test the tones for the three alert levels, press SVC (E) to select the weather service, then hold down ALT for about 1 second. The tones sound in the order L3, L2, then L1, and
TESt
flashes. Each alert code appears as its tone sounds. Press any key to end the test sequence.
NWR-SAME Code Detection Tests
The National Weather Service sends out daily, weekly, and monthly test (and sometimes demonstration) signals, which let anyone with a receiver (such as the
PRO-94) verify that the equipment is working properly.
To find out the specific test schedule in your area, contact your local NOAA or NWS office. Those offices are usually listed in the telephone book under US Government, Department of Commerce.
When
ALERT

20-524.fm Page 41 Tuesday, August 31, 1999 3:55 PM
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 important distinction 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.
41
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, 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, 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.
There are also hybrid systems which are a combination 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 THE SCANNER TO THE
TRUNKING MODE
Press TRUNK to switch between conventional scanning and trunking operation.
42
20-524.fm Page 43 Tuesday, August 31, 1999 3:55 PM
SETTING SQUELCH FOR THE
TRUNKING MODE
Your scanner’s squelch setting is automatically adjusted during trunking, which means it is not necessary 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.
We recommend you set SQUELCH fully clockwise before selecting a trunked bank.
Note: Change this setting as needed for the best performance in your area.
STORING TRUNKED
FREQUENCIES
Before you set up your scanner to track a trunked system, consider the following:
• The following frequency ranges are valid for the trunk systems indicated.
Motorola Type I and Type II system:
935.0125–939.9875 MHz
851.0000–899.9875 MHz
(except cellular frequencies)
406.0000–512.0000 MHz
137.0000–174.0000 MHz

Hint: While scanning, you may not know exactly to whom the talk group IDs are assigned until you listen awhile. To locate talk group ID lists for your local police, fire, and other agencies, refer to frequency guides available at your local RadioShack store or on internet sites such as www.trunkscanner.com. You can also determine the type of agency you are listening to after a short while, be it a police, fire, or emergency medical
2-way radio user. Once you have identified the type of service, note the associated talk group ID of that unit for future programming. See “Identifying a Trunked
Frequency” on Page 48. Determining the service associated with an talk group ID might take awhile, but dis-
46
20-524.fm Page 47 Tuesday, August 31, 1999 3:55 PM covering the ID owner of each signal is half the fun of trunk scanning!
Turning a Trunked Bank On or Off
Press DATA (ALT) during trunk scanning. The selected trunked banks appear. Press the bank number ( 0 – 9 ), to turn the desired bank on or off.
Skipping a Trunked Bank
You can skip to the next trunked bank during scanning by holding down SRC (LIMIT) for about 3 seconds.
Turning the Status Bit Ignore
(S-bit) On or Off
You can set how your scanner works with status bits
(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 0011, it reads the ID as 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.
Important: If you are scanning any system other than a Motorola Type I system, be sure status bit ignore is set to ON or you will miss some transmissions.
47
20-524.fm Page 48 Tuesday, August 31, 1999 3:55 PM
Follow these steps to turn status bit ignore on or off.
1. Hold down SCAN until the current status bit ignore setting ( ON or OFF ) appears.
2. Press ▲ to select ON or ▼ to select OFF , then press E (SVC) .
Identifying a Trunked Frequency
While ID scanning (looking for IDs within a trunked system) or performing an ID search, press W to see the current trunked frequency. (The frequency flashes twice.) Then hold down W until a confirmation tone sounds and the ID and the frequency alternately appear. To return to normal operation, press W .
Selecting the EDACS Talk Group
ID Format
The EDACS system uses two group ID formats: Decimal and Agency-Fleet-Subfleet (AFS). If you use a list of IDs shown in one format (for example AFS) and the
ID you want to receive is in the other format (for example, decimal), press SVC (E) to switch to the decimal format. The ID appears in decimal format.
E
flashes on the display when the decimal format is selected.
EDACS Talk Group ID Range Search
To search EDACS IDs faster, set a range for the Agency or Fleet listings. Enter the Agency (or the Agency and the Fleet) listing numbers using the number keys, then press SRC (LIMIT) . Note the following examples.
Example 1
Agency = 01
Press 0 1 .
SRC (LIMIT)
01---
appears during search.
Example 2
Agency = 01 Fleet = 01
Press 0 1 .
0 1 SRC (LIMIT)
01-01-
appears during search.
To stop an ID range search, press SRC (LIMIT) .

20-524.fm Page 49 Tuesday, August 31, 1999 3:55 PM
Using HOLD to Monitor an
Active Talk Group ID
Follow these steps to stop scanning and keep the scanner tuned to a desired ID.
1. Press HOLD (A/B) .
HOLD
appears and the scanner stays on the current ID.
2. If you want to listen to (and hold) a different ID, use the number keys to enter that ID.
3. Press HOLD (A/B) again.
HOLD
flashes, then the scanner monitors the ID.
4. Press SRC to resume searching for a data channel
(trunk scanning).
Temporarily Storing a Talk Group ID into the Monitor ID Memory
To store a talk group ID into a temporary monitor memory, press MON/CLR (•) . This lets you store the ID prior to moving it into a list memory. Press SRC to resume searching.
Note: To program the ID stored in the monitor ID memory into the ID scan list, see “Moving Talk Group IDs to
Talk Group ID Lists” on Page 54.
49
20-524.fm Page 50 Tuesday, August 31, 1999 3:55 PM
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 are 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.
To lock out an ID, press L-OUT (S/S) when the ID appears. The ID is locked out, and the next active ID appears.
Unlocking a Single Talk Group ID
1. Hold down L-OUT (S/S) until you hear two short beeps.
2. Repeatedly press
W
or
V
to select the ID you want to unlock.
3. Press L-OUT (S/S) . The ID is unlocked, and the next locked ID appears.
4. Press SRC (LIMIT) to resume the scanner’s previously selected function.
Unlocking All Talk Group IDs
Hold down L-OUT (S/S) while searching until you hear two short beeps, then press E (SVC) to unlock all the
IDs at once. The scanner beeps twice. Press L-OUT/SS to resume the search.
Note: When you unlock all the IDs, the scan list appears. Press SCAN to scan the IDs stored in your scan lists or press SRC (LIMIT) to resume the scanner’s previously selected function. For more information about scan lists, see “Using Talk Group ID Lists” on Page 52.
50
20-524.fm Page 51 Tuesday, August 31, 1999 3:55 PM
Using Trunk Scanning Scan Delay
Sometimes a user might pause before replying to a transmission. You can set the scanner to hold on an ID for 5 seconds to wait for a reply. That way, the scanner continues to monitor the ID for 5 seconds after the transmission stops before resuming scanning.
Press DELAY to turn trunk scanning scan delay on or off.
DLY
appears when the scan delay is set to on.
Note: If you consistently miss responses even with scan delay turned on, change the default system type or the fleet map being used. See “Scanning Type I and
Hybrid Trunked Systems” on Page 55.
Monitoring Talk Group IDs
You can use your scanner’s display to monitor the frequencies/talk group IDs of a trunked system for activity.
While you cannot hear conversations in this mode, it is an excellent way to determine which talk group IDs are the most active. To set the scanner to monitor IDs, hold down MON/CLR (•) until
SEARCH
and the channel number flash. All active group IDs appear in quick succession. To stop monitoring IDs, press SRC again.
Note: When you monitor IDs, any IDs you have locked out also appear.
51
20-524.fm Page 52 Tuesday, August 31, 1999 3:55 PM
CHANNEL ACTIVITY BARS
Your scanner displays up to 20 channel activity bars for the stored frequencies in a bank. These 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 bank 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 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 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
52
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 search, or automatically.
Manually Storing Talk Group IDs in Talk Group ID Lists
1. Select the trunking bank you want to use (see
“Scanning a Trunked Bank” on Page 46).
2. After the scanner begins trunk scanning, press
MAN . A number showing the current talk group ID list appears at the top of the display, and bars appear that show activity in other banks.
3. Press MAN again , then repeatedly press V or W to select the talk group ID list location (shown at the top of the display) where you want to store an ID.
Then press PROG .
4. Enter the type of ID you want to store, then press
E .
To enter a Type I ID, use the number keys to enter the block number and the fleet number, then press
• . Enter the subfleet number and press E.
To enter a EDACS ID, use the number keys to enter the agency number, then press • . Next, enter the fleet number and the subfleet number, then press E.
Note: To clear a mistake while entering an ID, press 0 then E , then start over at Step 1.
5. Repeatedly press PROG or
V
to select the next scan list location you want to program. Then repeat Step 4 to enter another ID.
6. When you finish, press E to store the entries.

Error
flashes twice and the scanner beeps several times, then the scan list numbers appear at the top of the display. To correct the entry, delete at least one of the incorrect IDs (see “Deleting a Stored Talk Group ID
List”).
To remove a scan list from active scanning, use the number keys to enter the scan list’s number. The scan list number turns off, and the IDs in that list are not scanned.
Note: One of the five scan lists must always be active.
You cannot remove all of them.
To restore a scan list to active scanning, use the number keys to enter the number of the list again.
Press SRC to return to the previously selected function.
Deleting a Stored Talk Group ID List

20-524.fm Page 55 Tuesday, August 31, 1999 3:55 PM
Priority Talk Group ID Scanning
You can assign a priority to a favorite ID so during scanning the scanner checks that ID more frequently than the others in the list. Each of the five memory locations reserved for storing lists (see “Using Talk Group
ID Lists” on Page 52) can have only one priority ID, and the ID assigned that priority in List 1 has the highest priority of all.
To assign a priority to an ID, press PROG . Enter the desired ID number (list number and location number), then press PRIORITY (H/S) .
P
appears.
To turn priority ID scanning on or off, repeatedly press
PRIORITY (H/S) during ID scanning or manual operation.
PRI
appears when priority scanning is turned on.
Note: Priority ID scanning does not operate when priority IDs are locked out. See “Locking Out Talk Group
IDs” on Page 50.
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).
55
20-524.fm Page 56 Tuesday, August 31, 1999 3:55 PM
Subfleet information is included with the frequency list for a Type I system. To enter the provided map, see
“Programming a Fleet Map” on Page 60.
Note: Review the content of website www.trunkscanner.com to locate suitable fleet map information.
If you do not already know the size codes used, you will have to guess. Since you do not have to figure out all the blocks at one time, this is not as hard as it might seem. Select a size code for a block, then press SRC .
Now listen to the communications. If you decide you are receiving most of the replies to the conversations, then you have probably selected the right size code and can programming the next block of the map.
There are 16 preset fleet maps to choose from, and it is best to start with these when setting up a Type I or hybrid trunk scanning 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 60).

W
to select
E1
, then press
E .
4. Press DATA (ALT).
5. Repeatedly press
V
or
W
to select the name of the desired map (example
E1P7
). The preprogrammed fleet map appears.
6. Press E (SVC) , then press SRC (LIMIT). The scanner then searches for transmissions using the preset map you chose.
Note: When the scanner searches for transmissions, you see Type I fleet and subfleet IDs such as
100-12
,
100-9
,
000-12
, or
400-8
.
How do you know if the preset map you selected is correct? Listen to find out if you are following complete conversations. If not, try another preset map.

to select the size code for the first block, then press E . The next available block appears.
Size Code
Block
8. Repeat Step 7 until you have selected a size code for each desired block.
9. Press SRC (LIMIT) . The scanner exits the trunking programming mode, tunes the data channel, then searches using the map you programmed.
Note: If you select size code S-12, S-13, or S-14, these restrictions apply:
• S-12 can only be assigned to Blocks 0, 2, 4, or 6
• S-13 can only be assigned to Blocks 0 and 4
• S-14 can only be assigned to Block 0
Since these size codes require multiple blocks, you will be prompted for the next available block when you program a fleet map. For example, if you assign Block 0 as
S-12, the scanner prompts you for
b2
, the next block available, instead of b1. If you assign Block 0 as S-14, you would not see another prompt because S-14 uses all available blocks.

Programming the Base and
Offset Frequencies
To properly track Motorola VHF and UHF trunked systems, you must program the applicable base and offset frequencies for each system.
A list of these frequencies can be found at www.trunkscanner.com and other similar frequency resources.
1. Set the scanner for conventional scanning. Press
PROG then TRUNK .
2. Press the number key of the bank where you want to store the base frequency.
3. Repeatedly press
V
or
W
to select
E2-VHi
or
E2-UHF
, then press E . A previously programmed trunked frequency appears
4. Press DATA (ALT) . The preset base frequency appears.
5. Enter a desired frequency.
6. Press DATA (ALT) . The preset offset frequency appears.
7. Enter the frequency using the number keys according to the following guide:
• For Motorola Type II VHF, (E2-VHF Hi band) use
5kHz steps between 5 kHz – 100 kHz.
• For Motorola Type II UHF, (E2-UHF band) use
12.5kHz steps between 12.5 kHz – 100 kHz.
Programming a Hybrid System
A hybrid system is simply a Type I system with some of its blocks designated as Type II blocks. To program a hybrid system, follow the steps listed in “Programming a Fleet Map” on Page 60. However, if you want a block to be Type II, instead of pressing
V
or
W
to select the size block (Step 7), enter size code
S-0
instead.

Turning On/Off the Motorola Disconnect
Tone Detect Function
While trunking a Motorola system, your scanner automatically tunes to the data channel when it detects a disconnect tone (a code that tells the trunking system that the transmitter has finished sending) on the voice channel.
You can manually turn off this function so the scanner does not tune to the data channel under those conditions. You might use this feature to listen to weak transmissions when conversations are generally disconnected.
To turn the disconnect tone detect function on or off, set the scanner to trunk track then press SVC . The scanner beeps and DATA flashes for about 5 seconds.
Notes:
• To set the scanner so it remains on the voice channel (even when a disconnect tone is transmitted or there is no signal at all) set SQUELCH so you hear a hissing.
• You cannot use the disconnect tone detect function if you are programming a trunking frequency or a fleet map.
To set the scanner to automatically tune to the data channel once again when it detects a disconnect tone, press SVC (E) .

Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created by the scanner’s internal circuits. These stray frequencies might interfere with broadcasts on the same or similar frequencies. If you program one of these frequencies, you hear only noise on that frequency. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie.

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.
