THE FCC WANTS YOU TO KNOW

This equipment has been tested and found to comply with the limits for a scanning receiver, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

This device may not cause harmful interference.

This device must accept any interference received, including interference that may cause undesired operation.

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), you are subject to fines and possible imprisonment for intentionally listening to, using, or divulging the contents of such a transmission unless you have the consent of a party to the communication (unless such activity is otherwise illegal).

This scanner has been designed to prevent reception of illegal transmissions. This is done to comply with the legal requirement that scanners be manufactured so 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 are illegal to monitor. Doing so could subject you to legal penalties.

In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area. It is also illegal in many areas to interfere with the duties of public safety officials by traveling to the scene of an incident without authorization.

We encourage responsible, safe and legal scanner use.

GETTING FAMILIAR WITH YOUR SCANNER

Though you may be anxious to begin using your new scanner right away, we recommend that you take the time to read this manual thoroughly so that you may fully understand the advanced features and capabilities of your PRO-96 scanning receiver.

Once you understand a few simple terms used in this manual and familiarize yourself with your scanner's features, you can put the scanner to work for you. You simply determine which frequencies and trunking systems you want to receive, and then program the scanner to scan them.

A frequency is the receiving signal location (expressed in MHz). To find active frequencies, you can use frequency guides available from your local RadioShack store, frequency listings posted on the Internet, or the built in search function.

Your scanner’s SEARCH banks contained preprogrammed frequencies in the scanner ’s memory (see “Searching a Preprogrammed Frequency Range” on Page 52 for the frequency list). You can even change the frequency range on one of the SEARCH banks (SR6) to customize your own search parameters.

Once you identify the frequencies you wish to monitor, you can store them into programmable memory locations called channels, which are grouped in channel storage banks. You can then scan the channel-storage banks to see if there is activity on the frequencies stored there. Each time the scanner fi nds an active frequency, it stops and monitors the radio traffic on that channel until the transmission ends, then resumes scanning. For detailed programming instructions, see “PROGRAMMING YOUR SCANNER” on Page 30.

Understanding Your Scanner’s Memory Organization

V -Scanners

A V-Scanner folder contains a complete, stored configuration profile of your scanner’s programming. Certain current scanner models allow the user to load, save and edit different scanner configurations using an interface cable, software and a personal computer. The PRO-96 V-Scanner feature extends this functionality by allowing you to store or recall up to eleven scanner configurations in V-Scanner folders on your scanner, without using a personal computer. You can use the V-Scanner feature to build and store configurations for different areas or different scanner applications. Using the cloning feature it is possible to exchange scanner configurations with your friends without losing your existing data. V-Scanners also provide a way for you to easily back up your programmed data without connecting your scanner to a personal computer.

Each V-Scanner folder stores all channel storage banks, channels, trunking Ids, search settings, and other parameters associated with the operation of the scanner.

Channel Storage Banks

A channel storage bank is a storage area for a group of channels. Channels are storage locations for frequencies. Whereas a channel can only contain one frequency, a channel storage bank can hold 50 channels.

To make it easier to identify and select the channels you want to listen to, your scanner divides the channels into 10 banks (0 to 9) of 50 (00 to 49) channels each, a total of 500 channels. You can use each channel -storage bank to group frequencies, such as those used by different public safety agencies and jurisdictions in your area. Channel storage banks can be easily enabled or disabled while scanning by pressing the number key that corresponds with the desired channel storage bank.

For example, a particular city might use four frequencies for police communications, and four frequencies for fire communications. You could program the police frequencies starting with 000 (the first channel in bank 0) and program the fire department frequencies starting with 100 (the first channel in bank 1). This gives you the ability to quickly select what you wish to monitor by activating or deactivating the appropriate channel storage bank. When looking at channel numbers, the first digit identifies the bank (0 to 9). The second and third digits identify the channel within the bank (00 to 49).

Channels

Channels are storage locations for the actual frequencies you wish to monitor. Each channel can be configured with a radio frequency, the desired mode for that frequency, and settings to allow a short delay after a transmission or lock the channel out from scanning operation. A channel can contain a conventional, non-trunked frequency, or a frequency used in a trunking system.

Search Banks

Your scanner has six preprogrammed search banks configured to search various radio services, and one limit search bank that you can configure. You can set the lower and higher frequency limit in the limit search bank.

Hint

• For example, if you wanted to find active frequencies between a range of 150.1000 and 150.5000, you would put both of those frequencies in the limit search bank.

Understanding Your Scanner’s Channel Receive Modes

You can program each channel with any one of six receive modes (AM, FM/Digital, CTCSS, DCS, Motorola, and EDACS).

Each receive mode affects how your scanner operates when scanning and receiving transmissions.

Note

• Trunked modes (ED and MOT) can only be selected for frequencies above 137 MHz.

• Your scanner ’s Closed Mode lets you hear transmissions from only those trunking

talkgroups you specify. For more information, see “Open and Closed Mode Operation” on Page 83.

AM Mode (AM)

The AM mode sets the scanner to receive transmissions using amplitude modulation (AM), primarily used for aircraft, military, 27 MHz citizen’s band, some amateur radio, and some government transmissions. (Refer to “SPECIFICATIONS” on Page 107 for a list of the frequencies covered.) When the scanner receives a transmission on a channel set to the AM mode, it always stops on the transmission.

FM/Digital Mode (FM)

The FM/Digital (FM) mode sets the scanner to receive transmissions using frequency modulation (FM) and APCO-25 digital modulation. FM is used for most public safety transmissions, as well as broadcast, business, and amateur radio transmissions. APCO-25 digital modulation is used in many newer conventional and trunked public safety radio systems. When the scanner receives a transmission on a channel set to the FM/Digital mode, it always stops on the transmission.

CTCSS Mode (CT)

CTCSS mode sets the scanner to receive transmissions using frequency modulation (FM) with Continuous Tone Coded Squelch System (CTCSS) subaudible tone codes. CTCSS allows multiple users to share a single radio frequency without hearing each other’s transmissions. In your PRO-96 scanner, the CTCSS feature can be used to block the reception of transmissions on shared channel to only those that use the CTCSS tone that you have specified. CTCSS mode also features a Code Search setting that allows you to instantly display and store unknown codes into the channel memory. CTCSS tones can sometimes be heard as a low “hum” in the background of a voice transmission.

Many systems that use CTCSS transmit a special “turn off code” at the end of each transmission. The turn off code causes a properly equipped receiver to mute before the transmission ends, eliminating the “squelch tail” burst of noise the commonly occurs when the signal is lost. CTCSS turn off code performance can be affected by weak signals.

DCS Mode (DC)

DCS mode sets the scanner to receive transmissions using frequency modulation (FM) with Digital Coded Squelch (DCS) subaudible data signaling. DCS is very similar to CTCSS, except that a digital code is transmitted instead of an audio tone. Like CTCSS, DCS allows multiple users to share a single radio frequency without hearing each other’s transmissions. In your PRO-96 scanner, the DCS feature can be used to block the reception of transmissions on shared channel to only those that use the DCS tone that you have specified. DCS mode also features a Code Search setting that allows you to instantly display and store unknown codes into the channel memory. DCS data can sometimes be heard as a low “purring” sound in the background of a voice transmission. Some DCS systems transmit a special “turn off code” at the end of each transmission. The turn off code causes a properly equipped receiver to mute before the transmission ends, eliminating the “squelch tail” burst of noise the commonly occurs when the signal is lost. DCS turn off code performance is typically more immune to weak signals than CTCSS.

Motorola/APCO-25 Trunking Mode (MO)

You can set your scanner so it decodes the talkgroup IDs used with Motorola and APCO-25 trunking systems and follows talkgroup calls in the trunking system. This setting is called the Motorola mode.

Motorola systems are trunking systems used primarily by business and public safety agencies to efficiently allocate a small number of frequencies (as few as three) to many groups of users (as many as several thousand). To do this, each group of users in the system is assigned to a specific talkgroup. For example, a city’s east side patrol officers might all be assigned to talkgroup 2160. One channel in the system is continuously transmitting data that identifies which talkgroups are active on which channel. In addition, this talkgroup information is also transmitted as subaudible data on each active channel.

When the scanner receives a transmission on a channel set to the Motorola mode, it first decodes the talkgroup ID data included with the transmission. In the Open Mode, the scanner stops on the transmission and displays the talkgroup ID on the bottom line of the display. In the Closed Mode, the scanner only stops on the transmission if the talkgroup ID matches a talkgroup ID that you have stored in the bank's talkgroup ID list and have not locked out.

Trunking systems covered by the Motorola mode come in four categories: Type I, Type II, Type I/II Hybrid and APCO-25. Each category displays and uses talkgroup IDs in slightly different ways.

Motorola Type I IDs are in the form FFF-SS, where;

FFF=Fleet ID

SS=Subfleet ID

Type I systems are usually organized with different user groups assigned to different fleets.

Note

• For example, a valid fleet-subfleet ID identifying all detectives within a police department might be 000-12, where 000 identifies all police users and 12 identifies the Detective division.

To properly map the raw Type I data to the correct fleet-subfleet format, you must program the correct fleet map into the scanner. Fleet map information is widely available on the Internet for most Type I systems in use.

Type II and APCO-25 system talkgroups are identified by a 5-digit number. Valid Type II talkgroup IDs are divisible by 16, while APCO-25 talkgroups are not. Use care to ensure that you enter the correct Type II IDs into your scanner. Type I/II hybrid systems use both fleet-subfleet and 5-digit formats for talkgroup IDs.

Note

• Tuning the scanner to an active control channel while in Motorola mode will display the Motorola System ID and the approximate control channel message decode success rate. This information can help you identify the Motorola trunking system that you are monitoring and the receive quality of the control channel signal.

EDACS Trunking Mode (ED)

You can set your scanner so it decodes the talkgroup IDs used with EDACS (GE/Ericsson/M/A-COM) trunking systems. This setting is called the EDACS mode.

EDACS systems are used primarily by business or private communications service providers, as well as by some public safety organizations. EDACS systems transmit active talkgroup information only on a dedicated control channel.

EDACS frequencies are organized in a specific order. Each frequency is assigned a Logical Channel Number (LCN). For the scanner to correctly switch to an active frequency, you must program the frequencies in LCN order, starting with Memory 01. EDACS talkgroup IDs are entered as a 4-digit decimal number from 0001 to 2047 or AFS (Agency Fleet Subfleet) number from 00-001 to 15-157.

When there is activity on an EDACS system, that information is sent out on the control channel. The scanner decodes the ID for the active talkgroup. In the Open Mode, the scanner then goes to the transmission and displays the talkgroup ID on the bottom line of the display. In the Closed Mode, the scanner only goes to transmissions with IDs that match talkgroup IDs you have stored in the bank's talkgroup ID list that are not locked out.

PREPARATION

Listening Safely

To protect your hearing, follow these guidelines when you use headphones.

• Set the volume to zero before putting on headphones. With the headphones on, adjust the volume to a comfortable level.

• Avoid increasing the volume once you set it. Over time, your sensitivity to a volume level decreases, so volume levels that do not cause discomfort might damage your hearing.

• Avoid or limit listening at high volume levels. Prolonged exposure to high volume levels can cause permanent hearing loss.

Traffic Safety

Wearing headphones while operating a motor vehicle or riding a bicycle can create a traffic hazard and is illegal in most areas.

Even though some headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard. Exercise extreme caution!

Power Sources

You can power your scanner from any of these sources:

Internal non-rechargeable batteries or rechargeable batteries (not supplied – see “Using Batteries” on Page 24).

Standard AC power (with an optional AC adapter – see “Using AC Power” on Page 27).

Vehicle power (with an optional DC adapter – see “Using Vehicle Battery Power” on Page 27).

Notes

• Connecting an AC or DC adapter to the scanner disconnects internal batteries when you use the supplied non-rechargeable battery holder, but it does not disconnect internal batteries when you use the supplied yellow rechargeable battery holder.

• If you install the yellow rechargeable battery holder, you can operate the scanner and recharge the rechargeable batteries at the same time. See “Using Batteries” and “Charging Rechargeable Batteries” on Page 24.

• If the scanner stops working properly after connecting it to power, try resetting it. See “RESETTING/INITIALIZING THE SCANNER” on Page 104.

• You must charge rechargeable batteries before you use them the first time. See “Charging Rechargeable Batteries” on Page 26.

Using Batteries

You can power the scanner with four AA batteries (not supplied). For the longest operation and best performance, we recommend alkaline batteries, available at your local RadioShack store.

You can use either the supplied non-rechargeable battery holder (black), or the supplied rechargeable battery holder (yellow). If you use the rechargeable battery holder, we recommend RadioShack nickel-metal hydride (Ni-MH) batteries.

WARNING

Never install non-rechargeable batteries in the rechargeable yellow battery holder. Non-Rechargeable batteries can get hot or explode if you try to recharge them.

CAUTION

• The battery holder fits only one way. Do not force it.

• Use only fresh batteries of the required size and recommended type.

• Always remove old or weak batteries. Old batteries can leak chemicals that destroy

electronic circuits.

• Do not mix old and new batteries, different types of batteries (alkaline or rechargeable), or rechargeable batteries of different capacities.

• If you do not plan to use the scanner with batteries for a month of longer, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

Follow these steps to install the batteries.

1. Press in on the top center of the battery compartment cover on the back of the scanner and slide the cover down to remove it.

2. Pull the battery holder out of the battery compartment.

3. If you are using non-rechargeable batteries, place them into the black holder as indicated by the polarity symbols (+ and -) marked on the holder.

If you are using rechargeable batteries, place them into the yellow holder as indicated by the polarity symbols (+ and -) marked on the holder.

4. Place the battery holder into the battery compartment.

5. Replace the cover.

When battery power is low, Low Battery! is displayed and the scanner beeps once every 30 seconds. When battery power is depleted, the scanner turns itself off. Replace all four non-rechargeable batteries, or recharge the rechargeable batteries. See “Charging Rechargeable Batteries” on Page 26.

WARNING

Always dispose of old batteries promptly and properly. Do not bury or burn them.

CAUTION

If you do not plan to use the scanner with batteries for a month or longer, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

Charging Rechargeable Batteries

Your scanner has a built-in charging circuit that lets you charge nickel-metal hydride (Ni-MH) or nickel cadmium (Ni-CD) rechargeable batteries (not suppl ied) while they are in the scanner. To charge rechargeable batteries, connect an appropriate AC or DC adapter to the PWR DC 9V jack. For best results we recommend RadioShack rechargeable nickel-metal hydride (NiMH) 1800 mAh batteries.

IMPORTANT

The EPA certified RBRC© Battery Recycling Seal on rechargeable batteries indicates RadioShack is voluntarily participating in an industry program to collect and recycle these batteries at the end of their useful life, when taken out of service in the United States or Canada. The RBRC program provides a convenient alternative to placing used rechargeable batteries into the trash or the municipal waste stream, which may be illegal in your area. Please call 1-800-THE-SHACK (1-800-843-7422) for information on rechargeable battery recycling and disposal bans/restrictions in your area. RadioShack’s involvement in this program is part of the company’s commitment to preserving our environment and conserving our natural resources.

To charge batteries with a DC adapter from a DC power source, you must use a 9V, 300 mA DC adapter such as RadioShack Cat. No. 273-1810 and a size C Adaptaplug™ (neither supplied). Both are available at your local RadioShack store. Make sure the adapter’s voltage is set to 9V.

It takes about 16 hours to recharge fully discharged 1800 mAh NiMH rechargeable batteries. You can operate the scanner while recharging the rechargeable batteries, but charging takes longer.

Notes

• The scanner can also charge Ni-Cd batteries. 600 mAh batteries require 6 hours and 850 mAh batteries require 8 hours to charge.

• When you charge Ni -Cd batteries, do not overcharge them. Overcharging shortens battery life.

• Rechargeable batteries last longer and deliver more power if you let them fully discharge once a month. To do this, use the scanner until Low Battery! appears in the scanner’s display. Then fully charge the rechargeable batteries.

Using AC Power

You can power the scanner using a 9V, 300 mA AC adapter and a size C Adaptaplug™ (neither supplied). Both are available at your local RadioShack store.

1. Connect the Adaptaplug™ to the adapter’s cord with the tip set to positive.

CAUTION

! 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 positive and its plug must fit the scanner ’s PWR DC 9V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

Note

• Always connect the AC or DC adapter to the scanner before you connect it to AC power source. When you finish, disconnect the adapter form AC power or the power source before you disconnect it from the scanner.

2. Plug the adapter’s barrel plug into the scanner’s PWR DC 9V jack.

3. Plug the adapter’s two-prong plug into an AC outlet.

Using Vehicle Battery Power

You can power the scanner from a vehicle’s 12V power source (such as cigarette-lighter socket) using a 9V, 300 mA DC adapter and a size C Adaptaplug™ adapter (neither supplied). Both are available at your local RadioShack store.

CAUTION

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 positive and its plug must fit the scanner’s PWR DC 9V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

Note

1. Connect the Adaptaplug™ to the adapter’s cord with the tip set to positive.

2. Plug the adapter’s barrel plug into the scanner’s PWR DC 9V jack.

3. Plug the adapter’s cigarette-lighter plug into your 12V power source.

Note

• If the scanner does not operate properly when you connect a DC adapter, unplug the DC adapter from the power source and clean the socket, or check the adapter’s internal fuse.

Antenna

Connecting the Supplied Antenna

To attach the supplied flexible antenna to the antenna jack on the top of your scanner, align the slots around the antenna’s connector with the studs on the antenna jack. Press the antenna down over the jack and turn the antenna’s base clockwise until it locks into place.

Connecting an Optional External Antenna

The antenna connector on your scanner makes it easy to use the scanner with a variety of antennas, such as an external mobile antenna or outdoor base station antenna. Your local RadioShack store sells a variety of antennas.

Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For length over 50 feet, use RG-8 low-loss dielectric coaxial cable. If your antenna’s cable does not have a BNC connector, you will also need a BNC adapter (not supplied, available at your local RadioShack store).

Follow the installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the antenna jack.

WARNING

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

Connecting an Earphone/Headphones

For private listening, you can plug an 1/8-inch (3.5 mm) mini-plug earphone or headphones (not supplied), available at your local RadioShack store, into the HEADPHONE jack on top of your scanner. This automatically disconnects the internal speaker.

Connecting an External Speaker

In a noisy area, an amplified speaker (not supplied), available at your local RadioShack store, might provide more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5 mm) mini-plug into your scanner’s HEADPHONE jack.

Note

• You must use an amplified speaker with this scanner. Non-amplified speakers do not provide sufficient volume for comfortable listening.
