FEATURES
Your RadioShack PRO-94 1000-Channel Handheld
Trunking Scanner is one of a new generation of scan-
ners designed to track Motorola Type I, Type II, hybrid
analog systems, (such as Smartnet and Privacy Plus)
plus GE/Ericsson EDACS. Those systems are exten-
sively used in many 800 MHz, 900 MHz, and UHF com-
munication 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 set of frequencies. Instead of...

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.
NWR-SAME Circuitry
 — lets you listen to coded
weather emergency information using Specific Area
Message Encoding.
Two-Second Scan Delay
 — delays scanning for about
2 seconds before moving to another channel, so you
can hear...

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 trans-
mission where conversations are often disconnected.
Manual Access
 — lets you directly access any chan-
nel.
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...

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 dif-
ferent electrical circuit from the receiver 
• contact your local RadioShack store for help

This scanner is designed to prevent reception of illegal
transmissions, in compliance with the law which re-
quires that scanners be manufactured in such a way as
to not be easily modifiable to pick up those transmis-
sions. Do not open your scanners case to make any
modifications that could allow it to pick up transmis-
sions that it is not legal to listen to. Doing so could sub-
ject you to legal penalties.
We encourage responsible, legal scanner use.
