emergency numbers can be called, even if the handset or keypad has been
locked. For additional information, see section

Push-to-talk

(PTT) provides instant voice connectivity to a group of persons.
Push-to-talk is a one-way (half-duplex) communication. When a person wants to
talk, he presses and holds down the
button. Letting go of the button gives
another person the opportunity to push-to-talk.
In order to participate in the conference, the group members must accept an
invitation received as a text message, see
6.7.1 Accept a PTT Invitation
.
If a member declines an invitation, the member can re-join the group/conference
later on, see
6.7.2 Re-join a PTT Group
on page 58.
A user can also invite a group of members to participate in a conference call by
calling a PTT group, see
6.7.3 Call a PTT Group
on page 58.
TIP: Set the automatic key lock to “On”, if it is desired to have key lock during an
ongoing call, see
10.7.2.1 Activate the Automatic Key Lock
