Page 9: Understanding The Display
Understanding your Scanner Understanding the Display The LCD provides important information about the status of the radio. The top row of icons provide status information. Beneath this row, there are 4 rows of 16 characters each that provide alphanumeric information such as frequencies and object names. The last row usually contains softkeys for F1, F2, and F3.
Page 10: Understanding Object Oriented Scanning
Understanding your Scanner 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.
Page 11 Understanding your Scanner 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.
Page 12 Understanding your Scanner 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.
Page 13: Scanner Features
Understanding your Scanner 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.
Page 14 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.
Page 15 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 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.
Page 17: Dashboard Installation
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.
Page 18: Connecting The Antenna
Scanner Setup 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.
Page 19: Powering Your Scanner
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.
Page 20: Vehicle (Direct)
Scanner Setup 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.

Transferring Data To or From another Scanner or PC You can transfer the programmed data to and from another PRO-652 or PRO-651 scanner using a connecting cable which has 1/8-inch (3.5mm) stereo (TRS) phone plugs on both ends (not supplied). See “Cloning”...
Page 22: Squelch And Attenuator
Scanner Setup Squelch and Attenuator The squelch and attenuator control the scanner sensitivity. If squelch is set too high, the scanner may scan slowly or stop on noise or silence. If this happens, adjust squelch using the steps above, or for conventional channels, set the correct subaudible squelch mode.
Page 23: Basic Settings
Scanner Setup Basic Settings The Global menu stores all of the radio-wide settings used by the scanner. The Global menu allows you to “tweak” these settings to your liking.

Page 39: Grouping Objects With Scan Lists
Organizing Objects Grouping Objects with Scan Lists By default, new objects are automatically assigned to Scan List 01. You can divide these objects into separate Scan Lists so that you can easily enable or disable groups of objects depending on what you want to scan.
Page 40: Changing Scan List Membership
Organizing Objects By application: You can group objects by their application. For example, you may wish to place law enforcement related objects for your area in one Scan List, ﬁre and rescue objects in another, and business related objects in yet another Scan List. By Favorites: The Favorites (FAV) Scan List is a powerful tool that can be used to quickly narrow (or expand) your scanning proﬁle.

Talkgroup Lockout Talkgroup lockout is similar to search lockout, as it allows you to lockout undesired talkgroups while searching for new talkgroup activity with wildcard TGRP objects.
Page 51: Object Searches
Object Searches Object Searches A powerful feature of your PRO-652 is the ability to define different types of frequency searches and process them while scanning. Frequency searches are just another type of Scannable Object in the hierarchy of the radio’s memory organization, so they can be manipulated and scanned in the same manner as conventional channels and trunking talkgroups.

Page 69: Scanner Memory
Scanner Memory V-Scanner Storage Your PRO-652 features two types of memory storage: • Main memory is used to store programming that is used for everyday monitoring and scanning. • Virtual Scanner (V-Scanner) memory is used to store complete copies of your scanner’s main memory for later recall. V- Scanner includes objects, global settings, and dedicated search conﬁgurations.
Page 70: Using V-Scanners
Scanner Memory Using V-Scanners You can save active scanner conﬁgurations (called “working” or “main” memory) to a V-Scanner storage folder for later use. Then recall the stored scanner conﬁgurations from a V-Scanner storage folder to main memory when you want to use them. When you recall a conﬁguration from a V-Scanner storage folder and use it in main memory, any changes you make while using the conﬁguration will not automatically be transferred to the...
