Features
ˆ
Your RadioShack Base Scanner is one of a
new generation of scanners designed to
track Motorola
Smartnet and Privacy Plus) and hybrid
analog trunking systems, and GE/Ericsson
(EDACS
many 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 set 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 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 trunking
scanner monitors the data 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 search banks for convenience. By
pressing a single button, you can quickly
search those frequencies most commonly
used by public service and other agencies.
This scanner gives you direct access to over
59,000 frequencies including those used by
police and fire departments, ambulance services, government agencies, air, and amateur radio services.
Your scanner includes these features:
Simultaneous Trunking Operation
tracks two trunking systems (Motorola and
Type I and II (such as
) type systems, used extensively in

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 listening to, using, or disclos-

CONNECTING THE ANTENNA
You must install an antenna before you can
operate the scanner.
To attach the supplied antenna to the antenna jack on the top of your scanner, thread
the antenna clockwise into the hole on the
top of the scanner.
The scanner's sensitivity depends on its location and the antenna's length. For the best
reception of the transmissions you want to
hear, adjust the antenna's length according
to the chart below.
Frequency Antenna Length
25–54 MHz Extend fully
108–174 MHz Extend 4 segments
216–225 MHz Extend 3 segments
406–1300 MHz Collapse fully
Connecting an Outdoor Antenna
Instead of the supplied antenna, you can
connect an outdoor base-station or mobile
antenna (neither supplied) to your scanner.

of antennas.
na from the scanner. Always use 50 ohm
coaxial cable, such as RG-58 or RG-8, to
connect the base-station or mobile antenna.
For lengths over 50 feet, use RG-8 low-loss
dielectric coaxial cable. If the antenna's cable does not have a BNC connector, you will
also need a BNC adapter (also available at
your local RadioShack store). Your local RadioShack store carries a wide variety of coaxial antenna cable and connectors.
Once you choose an antenna, follow the
mounting instructions supplied with the antenna. Then route the antenna's cable to the
scanner and connect the cable to the
connector.
Warning:
ing or removing an outdoor antenna. If the
antenna starts to fall, let it go! It could contact
overhead power lines. If the antenna touches
a power line, contact with the antenna, mast,
cable or guy wires can cause electrocution
and death! Call the power company to remove the antenna. Do not attempt to do so
yourself.
Caution:

ANT
CONNECTING AN EARPHONE/
HEADPHONES
When deciding on an outdoor antenna and
its location, consider these points:
• The antenna should be located as high
as possible.
• The antenna and antenna cable should
be as far as possible from sources of
electrical noises (appliances, other
radios, and so on).
• The antenna should be vertical for the
best performance.
To connect an optional base-station or mobile antenna, first remove the supplied anten-
Preparation
For private listening, you can plug an 1/8-inch
(3.5 mm) mini-plug earphone or headphones
(not supplied), available at your local RadioShack store, into the jack on the front
of your scanner. This automatically disconnects the internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use an earphone or headphones.
• Do not listen at extremely high volume
levels. Extended high-volume listening
can lead to permanent hearing loss.

• Set the volume to the lowest setting
before you begin listening. After you
begin listening, adjust the volume to a
comfortable level.
• Once you set the volume, do not
increase it. Over time, your ears adapt
to the volume level, so a volume level
that does not cause discomfort might
still damage your hearing.
CONNECTING AN
EXTENSION SPEAKER
In a noisy area, an extension speaker (not
supplied), available at your local RadioShack
store, might provide more comfortable listening. Plug the speaker cable's

Traffic Safety
Do not wear an earphone or headphones
while you drive a vehicle or ride a bicycle.
This can create a traffic hazard and can be illegal in some areas. Even though some earphones and headphones let you hear some
outside sounds when you listen at normal
levels, they still can present a traffic hazard.
ˆ
About Y our Scanner
Once you understand a few simple terms
used in this manual and familiarize yourself
with your scanner's features, you can put the
scanner to work for you. You simply determine the type of communications you want to
receive, then set the scanner to scan them.
A frequency is the receiving signal location
(expressed in kHz or MHz). To find active
frequencies, you can use the tune function.
You can also use the SEARCH banks, which
are preprogrammed frequencies in the scanner's memory (see “Searching a Preprogrammed Frequency Range” on Page 18 for
the frequency list). You can even change the
frequency range on one of the SEARCH
banks (SR5) to limit the search.
TRANSFERRING DATA TO
AND FROM ANOTHER
SCANNER OR A PC
You can transfer the programmed data to
and from another PRO-2053 or PRO-93 using a connecting cable which has 1/8-inch
phone plugs on both ends (not supplied).
Connect the cable between each scanner's
PC/IF
jacks. See “Cloning Programmed Data”
on Page 29. You can also upload or download the programmed data to or from a PC
using an optional PC interface kit available
through your local RadioShack store.
When you find a frequency, you can store it
into a programmable memory location called
a channel, which is grouped with other channels in a channel-storage bank. You can
then scan the channel-storage banks to see
if there is activity on the frequencies stored
there. Each time the scanner finds an active
frequency, it stays on that channel until the
transmission ends.

UNDERSTANDING BANKS
Channel Storage Banks
A bank is a storage area for a group of channels. Channels are storage areas for frequencies. Whereas a channel can only
contain one frequency, a bank can hold numerous channels.
To make it easier to identify and select the
channels you want to listen to, your scanner

channels. You can use each channel-storage bank to group frequencies, such as
those used by Motorola trunking, EDACS
trunking, Marine, CB, Police, Fire, Aircraft
and Ham (see “Typical Band Usage” on
Page 40).
For example, a police department might use
four frequencies, one for each side of town.

Search Banks
Your scanner has five preprogrammed
search banks and one limit search bank. You
can set the lower and higher frequency limit
in the limit search bank. (For the default set-
ting, see “Searching a Preprogrammed Frequency Range” on Page 18).
UNDERSTANDING YOUR
SCANNER'S MODES
You can program each channel with any of
four receive modes (AM, FM, MOT, and ED).
However, you can not program MOT (Motorola), or ED (EDACS) mode in VHF. Each receive mode affects how your scanner
operates when scanning and receiving transmissions, and also affects what transmissions you receive when you set the scanner
to the closed mode. See “Changing the Receive Mode” on Page 28.
AM Mode
The AM mode sets the scanner to receive
transmissions using amplitude modulation
(AM), primarily used for CB, aircraft, military,
some amateur radio, and some government
transmissions. (Refer to “Specifications” on
Page 52 for a list of the frequencies covered.) When the scanner receives a transmission on a channel set to the AM mode, it
always stops on the transmission.
FM Mode
The FM mode sets the scanner to receive
transmissions using frequency modulation
(FM), used for most public safety transmissions, as well as broadcast, business, and
amateur radio transmissions. When the
scanner receives a transmission on a channel set to the FM mode, it always stops on
the transmission.
Motorola Mode
You can set your scanner so it decodes the
talk group IDs used with Motorola trunking
systems. This setting is called the Motorola
mode.
12
About Your Scanner
Motorola systems are trunking systems used
primarily by business and public safety
groups to efficiently allocate a small number
of frequencies (as few as five) to many
groups of users (as many as several thousand). To do this, each group of users in the
system is assigned to a specific talk group.
For example, the east side patrol officers
might all be assigned to talk group 2160.
One channel in the system is continuously
transmitting data that identifies which talk
groups are active on which channel. In addition, this talk group information is also transmitted as subaudible data on each active
channel.
When the scanner receives a transmission
on a channel set to the Motorola mode, it first
decodes the talk group ID data included with
the transmission. In the open mode, the
scanner stops on the transmission and displays the talk group ID on the bottom line of
the display. In the closed mode, the scanner
only stops on the transmission if the talk
group ID matches a talk group ID that you
have stored in the bank's talk group ID list
and have not locked out.
Motorola trunking systems come in three categories: Type I, Type II, and Type I/II Hybrid.
Each category displays and uses talk group
IDs in slightly different ways.
Motorola Type I IDs are in the form FFF-SS,
where:
FFF=Fleet ID
SS=Subfleet ID
Type I systems are usually organized with
different user groups assigned to different
fleets. For example, a valid fleet-subfleet ID
identifying all detectives within a police de-
òòòVñð
òòòVñð
partment might be
, where 000 identi-
òòòVñðòòòVñð
fies all police users and 12 identifies the
Detective division.
To properly map the raw Type I data to the
correct fleet-subfleet format, you must program the correct fleet map into the scanner.
Fleet map information is widely available on
the Internet for most Type I systems in use.
Type II system talk groups are identified by a
5-digit number. Valid talk group IDs are divisible by 16. If you try to enter an invalid talk
group ID, the scanner rounds the ID down to
the next valid ID.
Type I/II hybrid systems use both fleet-subfleet and 5-digit formats for talk group IDs.
Note:

EDACS Mode
You can set your scanner so it decodes the
talk group IDs used with EDACS (GE/Ericsson) trunking systems. This setting is called
the EDACS mode.
EDACS systems are trunking systems used
primarily by business or private communications service providers, as well as by some
public safety organizations. EDACS systems transmit active talk group information
only on a dedicated control channel.
EDACS frequencies are organized in a specific order. Each frequency is assigned a
Logical Channel Number (LCN). For the
scanner to correctly switch to an active frequency, you must program the frequencies in
)<DFIPý òñ
LCN order, starting with
)<DFIPý òñ
)<DFIPý òñ)<DFIPý òñ
talk group IDs are entered as a 4-digit decimal number from 0001 to 2047 or AFS
(Agency Fleet Subfleet) number from 00-001
to 15-157.
When there is activity on an EDACS system,
that information is sent out on the control
channel. The scanner decodes the ID for the
active talk group. In the open mode, the
. EDACS

scanner then goes to the transmission and
displays the talk group ID on the bottom line
of the display. In the closed mode, the scanner only goes to transmissions with IDs that
match talk group IDs you stored in the bank's
talk group ID list which are not locked out.
Because EDACS scanning requires clear reception of the control channel at all times,
EDACS systems tend to have a smaller usable area. An external antenna can greatly
improve EDACS scanning in a fringe area. If
you are having trouble scanning an EDACS
system, try manually selecting the data channel. If you are getting good reception, the
á0(Vòñ
á0(Vòñ
scanner will indicate talk group
á0(Vòñá0(Vòñ
. Try
changing your location or using an outdoor
antenna to improve reception.
Open and Closed Modes
You can set your scanner to change the way
it receives signals. These settings, called
open mode and closed mode, affect how the
scanner receives signals from communications systems that use some type of closed
squelch (such as Motorola and EDACS systems).
You can set each of the scanner's channel
storage banks to open or closed mode.
In open mode, the scanner scans signals
transmitted in all systems. In closed mode,
the scanner scans signals transmitted only
under the following conditions:
• When the signals are in the FM mode.
• When the signals are in the MOT, or ED
mode and the signal's ID code matches
the programmed ID code.
You can also select the user or talk groups
you want the scanner to receive in closed
mode.
When you set a channel storage bank to
