Talkgroup; Fixed And Dynamic Groups - Motorola GP640 User Manual

Talkgroup

Talkgroup is an MPT personality following the
same rules or protocol, but is primarily for
talkgroup calls. In talkgroup personality,
talkgroups are contained in a Talkgroup list,
similar to the Contact list, which is scrolled and
selected using the Rotary Knob (1).
On selection of a talkgroup, you may send and
receive calls as described below.

Fixed and Dynamic Groups

These groups form part of the Talkgroup
Personality, such that when this personality is
selected your talkgroup list shows only these
groups.
A fixed group is a group of users, the address
(number/alias) of which is preprogrammed into
your radio by your dealer.
A dynamic group is a group of users, the
address (number) of which is sent to your radio
'over air' at any time via the system controller.
Therefore at any time you may become a
member of a dynamic group, able to receive
calls and (depending on how your radio is
programmed) send calls to that group.
English 22
Incoming calls to fixed and dynamic group
numbers are detailed in Receiving a Call.
To make an outgoing call to a selected
talkgroup, press the PTT and speak after the
confidence tone.
Calls are cleared in the normal manner.
If the system is busy an engaged tone will be
heard, release the PTT and wait for the
confidence tone. You may then proceed with
the call by pressing the PTT.
