PRO-2050 VHF/UHF TrunkTracker Scanner
(200-0430) Features Faxback Doc. # 46006
Your new RadioShack PRO-2050 VHF/UHF Air/800 MHz 300-Channel Trunk Tracker
Home Scanner is one of a new generation of scanners designed to track
Motorola Type I, Type II, (such as Smartnet and Privacy Plus), and hybrid
analog trunking systems, which are extensively used in many 800 MHz
communication systems.
Trunking communications systems lets a large group of 2-way users (or even
different groups of 2-way radio users) efficiently use a group of
frequencies. Instead of selecting a specific frequency for a transmission,
the 2-way radio user simply selects a talk group. The trunking system
automatically transmits the call on the first available frequency, and also
sends a code that uniquely identifies that 2-way radio user's transmission
on a different frequency called a data channel.
Since the trunking system might send individual 2-way radio user's calls
and response transmissions on different frequencies, it is difficult to
listen to trunked communications using a regular scanner. The PRO-2050
monitors the data channel frequency sent with a 2-way radio user's
transmission and instantly switches to an active frequency, so you can hear
the call and response for that 2-way radio user and easily "follow" the
conversation.
The scanner also lets you scan conventional transmissions, and is
pre-programmed with service-search 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 30,000 exciting frequencies,
including those used by 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:
Ten Channel-Storage Banks - lets you store 30 channels in each bank to
group channels so you can more easily identify
calls.
Five Scan Lists - lets you store up to 50 IDs in each tracking
bank (up to a total of 500).
Triple-Conversion Circuitry - virtually eliminates any interference from IF
(intermediate frequency) images, so you hear
only the selected frequency.
Scan Delay - delays scanning for about 2 seconds before
moving to another channel in conventional
mode, so you can hear more replies that are
made on the same channel. In trunk tracking
mode, it delays for about 5 seconds before
moving to another ID.
Lock-Out Function - lets you set your scanner to skip over
specified channels or frequencies when
scanning or searching, and skip over IDs when
tracking trunked systems.
Priority Channels - lets you program one channel in each bank
(10 in all). As the scanner scans a bank, it
checks the bank's priority channel every 2
seconds so you don't miss transmissions on
that channel.
Five Service-Search Banks - lets you search preset frequencies in separate
public service, police, fire/emergency,
aircraft and weather banks, to make it easy
to locate specific types of calls.
HyperSearch and HyperScan - lets you set the scanner to search at up to
300 steps per second (in frequency bands with
5 kHz steps) and scan at up to 50 channels per
second, to help you quickly find interesting
broadcasts. (The normal search speed is 100
steps per second).
Data Signal Skip - lets you set the scanner to skip non-modulated
or data signals during scanning and searches.
This lets the scanner avoid non-voice signals
making a scan or search faster.
Manual Access - lets you directly access any stored 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.
Supplied Telescoping Antenna- provides good reception of strong local
signals.
External Antenna Terminal - lets you connect an external antenna with a
BNC connector to the scanner for improved
reception of distant/weaker signals.
Memory Backup - keeps the channel frequencies stored in memory
for an extended time.
Key Confirmation Tones - the scanner sounds a tone when you perform an
operation correctly, and an error tone if you
make an error.
Duplicate Channel Alert - warns you when the frequency you are storing
already exists in memory.

FCC Notice
Your scanner might cause TV or radio interference even when it is operating
properly. To determine if your scanner is causing the interference, turn
off your scanner. If the interference goes away, your scanner is causing it.
Try to eliminate the interference by:
Moving your scanner away from the receiver.
Connecting your scanner to an outlet that is on a different electrical
circuit from the receiver.
Contacting your local RadioShack store for help.
If you cannot eliminate the interference, the FCC requires that you stop
using your scanner.
This device complies with Part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
Scanning Legally
Scanning is a fun and interesting hobby. You can hear police and fire
departments, ambulance services, government agencies, private companies,
amateur radio services, aircraft, and military operations. It is legal to
listen to almost every transmission your scanner can receive. However, there
are some electronic and wire communications that are illegal to
intentionally intercept. These include:
Telephone conversations (cellular, cordless, or other private means of
telephone signal transmission).
Pager transmissions
Scrambled or encrypted transmissions.
According to the Federal Electronic Communications Privacy Act (ECPA), as
amended, you could be fined and possibly imprisoned for intentionally
intercepting, using, or disclosing the contents of such a transmission
unless you have the consent of a party to the communication (unless such
activity is otherwise illegal). These laws change from time to time and
there might be state or local laws that also affect legal scanner usage.
