Limiting call time (transmit timer)
Your radio may limit the amount of time you can talk
(transmit) continuously, if it is programmed in this way.
This is known as the transmit or time-out timer and
allows other radio users to make calls on that channel.
The radio warns you before the transmit timer expires
by beeping three times. Also, the red status LED flashes
and a message appears in the display:
Finish your conversation as soon as possible and release
the PTT. For a short time, your radio may prevent you
from transmitting to allow other radio users to make
calls on the channel.
Understanding talkgroups
Note:
This feature is available for digital channels only.
Talkgroups are a collection of people (radio IDs) with
whom you want to have private conversations as
a group.
For example, a state's public safety agencies could have
the following talkgroups:
Q
Local talkgroups—used by a specific agency to com-
municate within their own local agency. It may even
be made up of a county of public safety officers.
Q
Regional talkgroups—used by large state agencies
that have regional divisions.
Q
Statewide talkgroups—used by an agency to com-
municate with a public safety member in another
region. Statewide talkgroups, as their name sug-
gests, enable public safety agencies to communi-
cate with each other from one end of the state to
the other.
