5-Tone Signaling 21
Call Acknowledgement
After you have made a 5-tone call, you may hear an
acknowledgement tone, beep, or series of tones
from your radio, indicating that your call has been
received. If you do not hear a tone, either:
■ the called radio is incapable of generating an
acknowledgement, or
■ the called radio is turned off, or
■ the called radio is out of range of your call.
Your radio may also be programmed to display the
status of the called radio:
Note: If any control head activity is
detected before any of the above messages
are displayed, the acknowledgement
sequence is no longer expected, and any acknowl-
edgement messages received will no longer be dis-
played.
Making a
5-Tone Group
Call
Your radio may be programmed so that you can
make 5-tone calls to a group of radios. When a
group call is sent, there is no acknowledgement
tone from any of the other users.
