6.1.1 During a Voice Call
When a call is placed, a
Call Progress Message
is displayed on the
Message Line
and the speaker emits
Call Progress
tones (See
Appendix A
for more details).
When the called radio is contacted, both radios will “ring” and display the
call setup icon.
When the called person answers, both radios will be connected and will
display the audio enabled icon.
A conversation can now take place by each operator, in turn, pressing their
Microphone PTT buttons and speaking.
When the call is finished, either operator can end the call by:
•
replacing the Microphone on its bracket
•
pressing the
Red Handset
button.
Note: If the called radio cannot be contacted (radio off or out of range) or
does not answer within a short period of time (dependant on the
Network - about 10-30 seconds), a Radio Busy or Unavailable
message is displayed and call-fail tones are emitted.
