Push-to-Talk
Push-to-Talk is available on the WLAN Handset 2211 only.
Push-to-Talk mode enables WLAN Handsets 2211 to operate in a group broadcast mode in
addition to the standard handset operation. The WLAN Handset 2211 supports eight multicast
channels with the current channel saved in the handset memory.
The call period
Push-to-Talk mode operates on the concept of a call period. The Push-to-Talk call period begins
with the first transmission and ends when there has been no two-way radio traffic on the channel
for 10 seconds.
The Push-to-Talk mode controls the handset keypad during the call period. Therefore, it is not
possible to use the keypad for any other functions. However, it is possible to place and receive
telephone calls.
Initiate a Push-to-Talk call
1 Press the Push-to-Talk button on the right side of the handset.
The “start transmit” tone sounds within two seconds. The channel is active and the display
screen shows the current active channel.
2 Speak into the handset’s microphone.
All WLAN Handsets 2211 that are monitoring that channel hear the transmission.
3 Release the Push-to-Talk button.
The “end transmit” tone sounds. The handset enters the waiting state, where it monitors the
channel for up to 10 seconds.
Receive a Push-to-Talk transmission
Upon receiving a Push-to-Talk transmission, the “receiving alert” tone sounds and the WLAN
Handset 2211 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.
IMPORTANT!
Pressing any other keys or buttons (such as the Up/Down/Select or keypad
keys) while in a Push-to-Talk call will terminate the call.
