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 radio's 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 talkgroup's 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 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
