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

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.
