Object abbreviations used in this document
We described how your new GRE scanner utilizes an Object
Oriented User Interface in the Introduction and Overview
sections of this manual. You learned that the key components of
this new user interface are the Scannable Objects, which are, of
course, “things that can be scanned”. As you begin to use your
new scanner, you will notice that the object names are
abbreviated so that they can easily fit into the 16 character LCD.
(Imagine what the radios display would look like if “Trunking
Talkgroup Object” was spelled out in its entirety every time it was
necessary to show it in the display.)

You should take a moment and become familiar with these
abbreviations now. For consistency, the same abbreviations for
the different object types are used in the radio and here in the
manual.

TGRP
TGRP is used to represent a 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 managed automatically by a special computer, called
a controller, or by other specialized hardware. For now, all you
need to know is this; if you want to monitor a talkgroup on a
trunked radio system, you must store that talkgroups parameters
in a TGRP object.

TSYS
TSYS is used to represent a 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 on the same trunked radio system, you create a
TSYS object with all of the system parameters, then specify that
