PRO-91 150-Channel Handheld Trunking Scanner
(200-0521) Features Faxback Doc. # 48456
Your RadioShack PRO-91 150-Channel Handheld Trunking Scanner is one of a
new generation of scanners designed to track Motorola Type 1 and Type ll
(such as Smartnet and Privacy Plus) and hybrid analog trunking systems,
which are extensively used in many 800 MHz communication systems.
Trunking communications systems let a large group of 2-way radio users) or
even different groups of 2-way radio users) efficiently use a large range
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-91 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 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 30,000 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 - virtually eliminates any interference from IF
Circuitry (intermediate frequency) images, so you hear
only the selected˙frequency.
Five Channel-Storage - you can store up to 30 channels in each of 5
Banks different banks to group channels so you can
more easily identify calls.
Five Scan Lists - you can store up to 50 trunking IDs in each
trunk tracking bank.
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 IDs when tracking
trunked systems.
Priority Channels - lets you program one channel in each bank (5 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. The normal search speed is
100 steps per second.
Hyperscan - the scanner automatically scans up to 50 channels
per second in frequency bands with 5 kHz steps,
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 modern
transmissions) during searches. This lets the
scanner avoid non-voice signals, making a search
faster.
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 - provides excellent reception and is designed
BNC Connector to help prevent antenna breakage. Or, you can
connect an external antenna.
Monitor Memories - lets you temporarily store up to 5 frequencies or
IDs.
Memory Backup - keeps the frequencies stored in memory for an
extended time if the PRO-91 loses power.
Three Power Options - lets 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.

FCC NOTICE
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), 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.
