Understanding Object Oriented Scanning
Your PRO-197 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

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
