FEATURES
Your new RadioShack PRO-90 300-Channel Trunk-
Tracker Scanner is the first of a new generation of scan-
ners designed to track Motorola Type I and Type II
(such as Smartnet, and Privacy Plus) and hybrid an-
alog 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 2-
way radio user simply selects a talk group. The trunking
system automatically transmits the call on the first avail-
able frequency, and also sends a code that uniquely iden-
tifies that 2-way radio user’s transmission on a different
frequency called a data channel.
Since the trunking system might send individual 2-way ra-
dio user’s calls and response transmissions on different
frequencies, it is difficult to listen to trunked communica-
tions using a regular scanner. The PRO-90 lets you select
and monitor the data channel frequency sent with a 2-way
radio user’s transmission, so you can hear the call and re-
sponse for that 2-way radio user and easily “follow” the
conversation.
The scanner also lets you scan conventional transmis-
sions, and is preprogrammed 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 31,000 excit-
ing 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 Circuitry — virtually eliminates any
interference from IF (intermediate frequency) images, so
you hear only the selected frequency.

Ten Channel-Storage Banks — let you store 30 chan-
nels in each bank to group channels so you can more
easily identify calls.
Five Scan Lists — let you store up to 50 IDs in each
tracking bank (up to a total of 500).
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 (10 in all) and then have the scanner check it
every 2 seconds so you don't miss transmissions on
those channels.
Five Service-Search Banks — lets you search preset
frequencies in separate police, fire/emergency, aircraft,
marine, 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 and
scan at up to 100 frequencies per second in frequency
bands with 5 kHz steps, to help you quickly find interest-
ing 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 searches. This lets
the scanner avoid non-voice signals, making a search
faster.
Key Lock — lets you lock the scanner's keys to help
prevent accidental changes to the scanner's program-
ming.
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.
