Trunking Operation
2 To respond to the call, press
the PTT button and talk.
If 20 seconds pass before
you press the Call button,
you will not respond privately
to the call just received.
Instead, when you press
Call, you enter the Private
Conversation Call state, as
described in "Initiate an
Enhanced Private
Conversation Call" on
page 87.
If the system is busy when
you attempt to answer the
call, a telephone-type busy
tone sounds and your radio's
BUSY indicator lights. When
a channel becomes
available, you receive a call
back, and your radio
automatically keys up for
three seconds so that you
can begin talking.
Note: If you do not press the Call button before pressing the PTT
button, your conversation will be heard by all members of the
talk group.
