Your RadioShack 1000-Channel Handheld Trunking Scanner is one of a new generation of scanners de­signed to track Motorola systems, (such as Smartnet GE/Ericsson EDACS used in many 800 MH z , 90 0 MHz, and UHF communica­tion systems.
Trunking comm uni ca tions 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 scanner lets you se lect an d moni tor the d ata chann el fre­quency sent with a 2-way radio transmission, so you can hear the call an d re sponse for that us er and more easi ly “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:

Features
5
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.
Digital Weather Alert
— uses the digital SAME (specific area message encoding) signal transmitted with weather alerts to identify the type of alert being issued.
Note:
This scanner does not use the specific area fea-
ture of SAME. It responds to all alerts received.
Two-Second Scan Delay
— delays scanning for about 2 seconds before moving to another c han nel , s o y ou ca n 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 do not miss transmissions on those channels.
Five Service Banks
— frequencies are preset in sepa­rate police (fire/emergency), aircraft, ham, marine, and weather banks, to m ake it eas y to loc ate sp ecific type s of calls.
Auto Backlight
— automatically turns on the backlight
when the scanner receives signals.
Simultaneous Trunking Operation
— allows the scan­ner to trunk two trunk in g s yst ems, Motorola and EDACS, at the same time, as well as conventional systems.
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.
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 Liquid-Crystal Display
— lets you directly acces s any chan ne l.
— makes it easy to view and
change programming information.
Display Backlight
— makes the scanner ea sy to re ad in

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 o utd oor ante nna . 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.
CONNECTING AN EARPHONE/ HEADPHONE
For private listening, you can plug an optional earphone or mono headphones into the jack on top of your
Preparation
15
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 th at does not caus e disco mfor t 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.
16 Preparation
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 in to you r scan ner’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.

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 27).
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 Page59).
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).
22 About Your Scanner
Monitor Memories
The scanner also has 10 temporary memory locations called monitor memories.

Trunking Operation
ˆ
The scanner tracks transmissions that use the Motorola Type I, Type II, hybrid, and Ericsson EDACS analog trunking systems. The frequencies for many of the 800 MHz, 900 MHz, and EDACS public safety systems are listed in the separate
System Frequency Guide
National Public Safety Trunked
included with your scanner.
TYPES OF TRUNKING SYSTEMS
This trunking scanner monitor s 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 ra dio us­er’s talk group when that user presses their PTT (push to talk) control. Thus, trunking systems, in general , all ocate a few frequencies among many dif ferent users. Motorol a Type I and Type II systems achieve the same results in a slightly different way. One important di stinction between these systems is the amoun t o f d ata tr ansmi tt ed by each radio when the operator pushes the PTT control. A Type I system transmits the radi o’s ID and its curren t affiliation or the trunk system to which it b elongs. A Typ e II syst em 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.
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 availabl e police radios woul d then be assigned to one of the police subfleets, letting the police
38 Trunking Operation
centralize their communications and control the type of users on a sin gle system. Determini ng the exact fleet­subfleet 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 dat a sent when a user tr ansmits must conta in the radio’s ID, its f lee t in form ati on, 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 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 Page51).

SETTING THE SCANNER TO THE T RUNKING MODE
Simultaneous Trunking
The scanner allows you to track up to 10 systems at a time. You can trunk scan or search and scan conven­tional frequencies at the same time. You can also pro­gram conventional frequencies in the same bank as trunking systems.
After the scanner is finished checking activity in the trunked system, it scans other conventional frequencies in the bank. (Only trunking frequencies are programmed in trunk mode.)
If a system is ina cti ve for 1 s ec ond an d th ere are no con­ventional channels in the bank, the scanner starts scan­ning the nex t selected trunk bank. If you turne d on, the scanner starts scanning the next trunk bank after about 5 seconds.

CHANNEL ACTIVITY BARS
Your scanner displays up to 20 channel activity bars for the stored frequencies in a ba nk. Th ese ba rs indi cate th e 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 s tore i n a trunking bank has a co rre­sponding 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 w ith out an y v oic e tra nsm is -
sion, 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 interconn ect call or a priva te 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 Page40), your scan­ner sets up five scan lists for that one bank in which you can store your favorite IDs. Each list can contain up to 10 IDs, for a total of 50 IDs for each trunk scanning bank. If you us e a ll the banks as trunking ban ks , y ou ca n store 1000 IDs.
Talk group ID lists help you to organize trunking system users into c at e go rie s . Fo r ex a mp l e, y ou m ig h t us e Li st 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 ma nua lly , d urin g a search, or automat­ically.

SCANNING TYPE I AND HYBRID TRUNKED SYSTEMS
Your scanner is preset t o sca n Type II syste m ID s. Whe n you scan trunked frequencies, each Type II user ID you see appears as an even number without a dash (exam­ple 2160). Your scanner can also scan Type I trunked systems. Each Type I ID appears as a thre e- 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 38 and “Turning the Status Bit Ignore (S-Bit) On or Off” on Page 43).
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 55.
Note:
To locate suitable fleet map information, review

FREQUENCY CONVERSION
The tuning l oca tio n of a st ati on ca n be exp re ssed i n fr e­quency (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, multip ly 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
ˆ
Your RadioShack 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, whic h can cause premat ure wear of parts.
2
and 9, turn on the scanner.
CLEAR
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 da mp cloth occa­sionally to ke ep it lo oki ng new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the scanner.
Care and Maintenance
69
Modifying or tampering with the scanner’s internal components can cause a malfunction and might inval­idate its warranty and void your FCC authorization to operate it. If your scanner is not performing as it should, take it to your loca l RadioShack st ore for as­sistance.
