Capacity Max Operations
Capacity Max is a control channel-based trunked radio
system. Features that are available to the radio users
under this system are available in this chapter.
Push-To-Talk (PTT) Button
The PTT button serves two basic purposes.
• While a call is in progress, the PTT
button allows the
radio to transmit to other radios in the call. The
microphone is activated when the PTT button is
pressed.
• While a call is not in progress, the PTT button is used to
make a new call.
Press and hold the PTT button to talk. Release the PTT
button to listen.
If the Talk Permit Tone or the PTT Sidetone is enabled,
wait until the short alert tone ends before talking.
If the Channel Free Indication feature is enabled on your
radio (programmed by your dealer), you will hear a short
alert tone the moment the target radio (the radio that is
receiving your call) releases the PTT button, indicating the
channel is free for you to respond.
You hear a continuous Talk Prohibit Tone if your call is
interrupted, for example when the radio receives an
Emergency call. You should release the PTT button.
Programmable Buttons
Depending on the duration of a button press, your dealer
can program the programmable buttons as shortcuts to
radio functions.
Short press
Pressing and releasing rapidly.
Long press
Pressing and holding for the programmed duration.
NOTICE:
See Emergency Operation on page
395 for more
information on the programmed duration of the
Emergency button.
