Making a group call
Press the PTT button to make a call to the standard group. A tone signal
indicates that access has been granted and the telephone displays your
nickname and your group name. To make a call to a group other than the
standard group, select the
Group list option in the PTT menu, scroll to the
desired group and press the PTT button.
Hold down the PTT button for as long as you continue to talk. Hold the te-
lephone out in front of you so that you can see the display. When you are
finished talking, release the PTT button. The first person to press the PTT
button is the one who can speak. When one person is finished speaking,
the next person to push the PTT button can then speak.
Making an individual call

added the PTT address, select
List of participants. Scroll to an entry
and press the PTT button. You can also select your dialog partner from
the address book.
• To start an individual call from the list of PTT groups, select

and scroll to the desired group. Select Option > Active participants,

requests, select

press the PTT button.
Receiving a PTT call
A short signal tone informs you of an incoming group of individual call.
When a group call is being received, the group name and the nickname
of the caller are displayed. When an individual call is being received from
a person whose information you have saved in the address book, the
saved name (if available) will be displayed, otherwise only the nickname
of the caller will be displayed.
You can accept or reject an incoming individual call if you have set the
telephone for notifying you of individual calls.
If you press the PTT button to answer a group while another group mem-
ber is speaking, a wait tone will sound and the message
Wait queue will
appear on the display while you press the PTT button. Hold down the PTT
button and wait until the other person is finished speaking. Then, you can
speak.
