PRO-2050 VHF/UHF/Air/800 MHz 300-Channel Trunk Tracker Home Scanner
(200-0430A) Features Faxback Doc. # 61189
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 - lets you store 30 channels in each bank to
Banks 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 - virtually eliminates any interference from IF
Circuitry (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 - lets you search preset frequencies in separate
Banks 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 - provides good reception of strong local signals
Antenna
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.
Disconnect Tone Detect - the scanner automatically tunes to the trunking
data channel when it receives a disconnect
transmission. You can turn this feature off to
continuously monitor a channel with a weak
transmission on disconnected conversations.
We recommend you record your scanner's serial number here. The number is
on the back panel.

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 the following methods to eliminate the
Interference:
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.
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 Federal 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 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.
