Understanding Object Oriented Scanning
Your PRO-652 scanner utilizes an entirely new method of
programming called Object Oriented Scanning. In Object Oriented
Scanning, all “Scannable Objects” are treated the same. Scannable
Objects include talkgroups on trunked radio systems, conventional
non-trunked frequencies, limit searches, service searches, and Signal
Stalker II configurations. All these Scannable Objects are created,
edited, grouped, scanned and deleted using the same methods.
Scannable Objects can also be searched, filtered, and locked out.
Scannable Objects are mapped to Scan Lists, which can be named,
enabled, and disabled. There is even a Favorites Scan List. It is
easy to search for new frequencies or talkgroups and add them to
Scan List groups. It is also easy to delete or deactivate objects and
Scan Lists that you do not want to listen to, including a powerful
temporary lockout mode that allows you to zero in on activity
associated with a specific incident, then restore your desired
configuration when the incident is over.
Object Oriented Scanning is completely different from any prior
scanning receiver technology. Accordingly, some users may find it
difficult to visualize and understand how Object Oriented Scanning
works. This may be especially true for users who are familiar with
more recent scanning receiver technologies.
We suggest that you keep the following Object Oriented Scanning
Tenets in mind as you proceed with your study of this manual.
1. Memory organization is nothing more than a large list of
Scannable Objects.
2. A Scannable Object is simply “something that can be scanned,”
including conventional channels, trunking talkgroups, limit
searches, service searches, and Signal Stalker II setups.
3. There are no “systems,” “banks,” “groups,” “sub-groups,” or
“ID lists.” There is simply a very large collection of objects, each
Understanding your Scanner

10
11
with their own attributes. Scannable Objects all exist at the same
level or hierarchy within the scanner—no single type of Scannable
Object is more important than another, and Scannable Objects
do not have dependencies on or links to other Scannable Objects
in order for them to function properly.
4. The primary method of grouping the collection of objects is by
mapping them to Scan Lists. Mapping a Scannable Object to
one or more Scan Lists does not change the physical location
of the object in the memory system. When an object is mapped
to one or more Scan Lists, the object itself has not moved nor
changed from what it is—a simple, standalone object that is part
of a larger collection.
Object abbreviations used in this manual
Object names are abbreviated so that they can easily fit into the 16
character LCD. You should take a moment and become familiar with
these abbreviations now.
CONV – Conventional Channel Object
A CONV object is a regular, non-trunked frequency used for radio
communications. CONV objects are used to store the parameters for
any radio channel that is not a part of a trunked system. For example,
if you want to monitor specific VHF marine channels, they should be
programmed as CONV objects. If you want to monitor your favorite
amateur radio channel, it should be stored as a CONV object. If
your police or fire department uses a channel, or channels that are
not trunked, but part of a “plain old radio system,” they should be
stored as CONV objects.
TGRP – Trunking Talkgroup Object
Trunking Talkgroups are “virtual” channels that exist on a trunked
radio system. A trunked radio system is a radio system where a
small group of radio channels are automatically shared between a
larger number of users and user groups. This sharing of channels is
Understanding your Scanner

12
13
managed automatically by a special computer, called a controller, or
by other specialized hardware. If you want to monitor a talkgroup on
a trunked radio system, you must store that talkgroup’s parameters in
a TGRP object.
TSYS – Trunking System Object
A TSYS is a special object type that is used when creating TGRP
objects. A trunking talkgroup must be associated with a specific
trunked radio system in order for it to operate. There are parameters
that are associated with trunking systems, such as the type of trunked
radio system technology used, the frequencies that the system uses
to broadcast control data, etc. Instead of entering these parameters
over and over again every time you create a new TGRP, you create
a TSYS object with all of the system parameters, then specify that
TSYS object for each TGRP you create on the same trunked radio
system. A TSYS cannot be scanned by itself and is not considered
a Scannable Object. It is a “configuration object” that can be used
over and over again when adding talkgroups for a specified trunked
radio system.
LMIT – Limit Search or Search Range Object
LMIT objects contain the parameters necessary for the radio to
search a range of individual frequencies between a lower and upper
limit frequency.
SRVC – Service Search Object
SRVC objects are further divided into Public Safety, Aircraft, Amateur,
CB, Marine, and FRS/GMRS/MURS/DOT. SRVC objects are similar
to LMIT objects, but are preprogrammed to search all frequencies
associated with the selected service.
STLK – Signal Stalker II Object
STLK objects contain the parameters necessary for the radio to
rapidly sweep a range of radio spectrum for strong signals from
nearby transmitters.

Scanner Features
Object Oriented User Interface is designed for ease of use, yet is
powerful enough to satisfy the most sophisticated experts. Common
data entry, browsing and control methods are used for non-trunked
conventional channels, trunking talkgroups, search configurations and
Signal Stalker II setups. The radio grows with you—you can start out
with a small, easy to manage configuration, then expand it whenever
you need to.
Menu Driven Programming with Context Sensitive Help – Each
menu item provides a few lines of help text that provide assistance
with programming and using the scanner.
Scan List functionality allows you to arrange, group and scan objects
according to your preference.
Free-Form Memory Organization – Memory is assigned as objects
are created using a sophisticated internal file management system.
You are not constrained to traditional bank or channel scanner
memory layouts. The scanner can store over 1,800 conventional
channels, trunking talkgroups, search configurations, and Signal
Stalker II objects in any combination.
V-Scanner Technology – Allows you to save complete radio
configurations within the radio, for recall into main memory as
needed in the field. Twenty one V-Scanner Folders are provided,
each capable of storing over 1,800 objects. Total memory capacity of
main memory combined with V-Scanners is over 37,800 objects.
Skywarn Storm Spotter Functionality – Instant access to
frequencies used by storm spotter networks. You can monitor
storm conditions as they occur, and become aware of dangerous
conditions before the media or emergency management officials
announce them to the general public.
SAME and All Hazards Weather Alerting – Your scanner can
alert you to severe weather and other hazards in the specific areas
Understanding your Scanner

14
15
that you select. Your scanner can check your local NOAA weather
frequency periodically, even while scanning, and alert you when an
All Hazards alert occurs.
Multi-System Trunking – Scans most common trunked radio system
signaling formats, including Motorola, EDACS, LTR and P25 trunked
radio networks. Both talkgroup and individual call monitoring are
supported.
Automatic Adaptive Digital Tracking – When monitoring P25 digital
systems, instantly adapts the digital decoder to the digital modulation
format of the transmitted signal, then analyzes the signal over 50 times
each second and adapts to any subtle changes caused by multipath or
fading. No cumbersome manual adjustments are required.
Digital AGC – Instantly compensates for low user audio levels that
are common on digital systems.
LTR Home Repeater AutoMove – Takes the guesswork out of
programming LTR trunking systems when the home repeater order is
not known. Enter the LTR system frequencies in any order, and the
PRO-652 will automatically move the frequencies to the proper home
repeater slots as transmissions are received on the system.
Subaudible Squelch Decoder – CTCSS and DCS subaudible
squelch coding is processed by the same powerful DSP chip that is
used for P25 digital decoding. Provides fast and reliable decoding of
subaudible squelch signaling with squelch tail elimination.
Signal Stalker II – Quickly sweeps the scanner’s frequency ranges for
transmissions from nearby sources.
P25 NAC Functionality – P25 Network Access Code (NAC) is used
to provide selective squelch operation on conventional digital
channels. Your PRO-652 will detect the NAC that is being used on
a P25 conventional digital channel, and allow you to program NAC
codes to block transmissions that do not have a matching NAC,
including analog traffic on the same frequency.
Understanding your Scanner

Alert LED – Programmable tri-color LED can be configured to
illuminate or flash when certain objects are active. Eight user-defined
colors and brightness levels can be specified from thousands of
possible combinations.
Audible alarms – Programmable audible alarms can be configured
to sound when certain Scannable Objects are active. Can be used in
conjunction with, or separately from, the Alert LED described above.
High Speed PC Interface – Use a USB Scanner programming
cable for full duplex mode at 6 times the speed of previous scanner
models for PC transfer and 8 times the speed of previous models for
radio to radio cloning. High speed scanner programming cables are
available at your local RadioShack store or RadioShack.com.
Real-time Signal Strength Indicator – Shows relative strength of
received signals.
IMPORTANT NOTICE: The PRO-652 Digital Scanner will not receive
encrypted radio communications, or radio transmissions that utilize
ProVoice digital modulation.

Scanner Setup
Installing Your Scanner
You can mount your scanner in your vehicle or use it as a base
station.
Setting up a Mobile Base
You can place your scanner on a desk, shelf, or table to use it as a
base station. Because the speaker is on the bottom of the scanner,
use the mounting bracket to elevate your scanner off the surface for
better sound.
To use the scanner on a flat surface:
1. Attach the three protective
rubber feet to the
mounting bracket.
2. Slide the scanner into
the bracket, aligning
the scanner’s side holes
with the holes in the
bracket,
and then screw the
mounting knobs into the scanner.
Bracket Mounting
You can mount your scanner under or on top of the dashboard a
desk, shelf, table or other flat surface, using the mount bracket.
1. Use the supplied mounting bracket as a template to make
positions for the two mounting screws.
2. At the marked positions, drill holes slightly smaller than the
screws. When drilling holes, avoid obstructions behind the
mounting surface.

Scanner Setup
3. Attach the mounting bracket
to your vehicle’s surface using
the supplied screws and
lockwashers.
Note: Do not use the rubber feet if
you are mounting the bracket with
screws.
Dashboard Installation
If you are unsure how to install your scanner in your vehicle, consult
your automobile manufacturer, dealer, or a qualified installer.
To mount in your dashboard, you must connect an external antenna
and speaker.
1. Before installing, confirm your scanner fits in the desired
mounting area and you have all the necessary materials. Your
scanner requires a 2 x 7 1/8x 5 5/16 inch (50 x 180 x 135 mm) space.
2. Remove the four rear screws and pull off the black case before
installing your scanner.
3. Install the DIN sleeve into the opening in your dashboard, lip
facing out.
4. Push out the top and bottom tabs to hold the sleeve firmly in place.
5. Slide the scanner into the sleeve until it locks in place.

18
Scanner Setup
19
To remove your scanner from
the DIN sleeve, insert the two
keys straight into the scanner’s
front panel and pull the
scanner out.
Connecting the Antenna
You must install an antenna
before you can operate
the scanner. The supplied
telescopic antenna helps
your scanner receive strong
local signals. To install the
antenna, align the antenna
slots with the tabs on the
scanner, and slide the
antenna into place. Turn
and push down until the
antenna locks into place.
To connect an external antenna, follow the installation instructions
supplied with the antenna. Use 50-ohm coaxial cable, such as RG-58
or RG-8X, to connect an outdoor antenna. For lengths between 50
and 100 feet, use RG-8X low-loss dielectric coaxial cable. For lengths
over 100 feet, use RG8. You also may need a BNC adapter (not
supplied).
WARNING: Use extreme caution when you installing 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.

Scanner Setup
Powering Your Scanner
You can power your scanner from a wall outlet, or from your vehicle’s
battery.
You must use a power source that supplies 12V DC and delivers at
least 600 mA. Its center tip must be set to positive and its plug must
fit the scanner’s DC 13.8V jack. The supplied AC adapter and DC
power cord meet these specifications. Using a power source that
does not meet these specifications could damage the scanner or the
adapter.
Wall Outlet
1. Connect the tip of the supplied AC adapter to the DC 13.8V jack
at the rear of your scanner.
2. Plug the AC adapter into your wall outlet.
To prevent electric shock, do not use the AC adapter’s polarized
plug with an extension cord, receptacle, or outlet unless you can fully
insert the blades to prevent blade exposure.
Note: To avoid injury, do not connect the provided power adapter to
a ceiling outlet.
Vehicle (Power Socket)
To power your scanner from a 12V power source in your vehicle, such
as a cigarette-lighter socket, you need a 12V, 600 mA DC cigarette-
lighter adapter (not supplied), available at your local RadioShack
store.
1. Insert the adapter’s barrel plug into the scanner’s DC 13.8V jack.
2. Plug the adapter’s other end into your vehicle’s cigarette lighter
or power socket.
Note: When you use a cigarette-lighter adapter, you might hear
electrical noise from your engine while scanning. This is normal. This
is less of a problem if you connect directly to the vehicle fuse box.

20
Scanner Setup
21
Vehicle (Direct)
1. Disconnect the cable from your vehicle battery’s negative (–)
terminal.
2. Ground the black wire of the supplied DC power cord to your
vehicle’s chassis. The grounding screw must make complete
contact with your vehicle’s metal frame.
3. Connect the red wire of the supplied DC power cord to a
voltage source that turns on and off with the ignition switch, such
as a spare accessory terminal in your vehicle’s fuse box.
4. Insert the power cord’s barrel plug into the scanner’s DC 13.8V jack.
5. Reconnect the cable to your vehicle battery’s negative (–) terminal.
Headphones and Speakers
You can plug headphones or an external speaker (neither included)
into your scanner.
To use headphones, connect the plug into the headphone jack
on the front panel. Headphones automatically mute the scanner’s
speaker.
To use an external speaker, connect the plug into the EXT SP jack on
the rear panel.
Listening Safety
To protect your hearing, follow these earphone or headphones
guidelines:
•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 listening. Turn on the
scanner, then adjust the volume to a comfortable level.
•After 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.
