Receive a Push-to-Talk transmission
Upon receiving a Push-to-Talk transmission, the “receiving alert” tone sounds and the handset
enters the receive state.
In this state, the handset receives all conversations on the selected channel. The display shows the
current active channel, the caller ID of the current transmitter, and an indication that the handset is
receiving a broadcast transmission.
At the end of a transmission, the handset enters the waiting state, where it monitors the channel for
up to 10 seconds and displays “Waiting” on the screen. If no other transmission occurs within 10
seconds, the “end call” tone sounds and the handset becomes idle.
