PTT Operation
To start a Push-to-Talk call, push and hold the Push-to-Talk
(PTT) Button
on the BEAM handset, and continue to hold
the button until you are granted the floor to talk. Initially, you
will hear a series of connecting tones that will beep on one
second intervals, followed by either a Talk Tone (three notes
in ascending tone in rapid succession) or a Reject Tone (two
notes in descending tone in rapid succession) that will occur
if the service is busy or unavailable (a corresponding message
will be displayed on the screen when this occurs).
After receiving the Talk Tone, continue holding the
PTT
Button
and be sure to keep the button pressed while you
are speaking and to release it when you are finished. You will
have up to 20 seconds to speak during each transmission
before the floor becomes open for others to speak.
If you have configured your device with Talk Timer
Enabled,
the time remaining to speak in the current talk period is
displayed on the screen below the Device Name.
When 20 seconds has elapsed,
Time Expired
is displayed on
the screen and the device moves to the OPEN status, giving
others in the talkgroup session a chance to speak.
