In Group Calls, press and hold the PTT to talk
and release it to listen. Upon pressing the PTT,
you will hear one of the following alert tones:
A high, chirp-like tone indicates that you
have permission to talk. Begin speaking after
the tone.
A low, continuous tone indicates that you
cannot talk at this time. Wait a moment and
try again.
A busy-like tone indicates that the system is
busy. Wait for a call-back (high, chirp-like)
tone, then try again.
A time-out timer limits the amount of time you
can continuously talk. When the allotted time
expires, you will hear a low-pitched cut-off
tone.
Your unit may be pro-
grammed with a courtesy
tone. Upon releasing the
PTT, a courtesy tone
alerts listeners that you
have completed your
transmission.
A Group Call consists of a service area and a talkgroup. Service areas are
geographic areas of coverage for your radio. Your specific service areas are
defined by your service provider. A talkgroup is an organization of radio
users who communicate with each other.
