service implemented over a GSM/GPRS network. Push to
talk provides direct voice communication connected with
the push of a key. Use push to talk to have a conversation
with one person or with a group of people.
Before you can use push to talk, you must define the
push-to-talk access point and push-to-talk settings. You
may receive the settings in a special text message from

In push-to-talk communication, one person talks while the
others listen through the built-in loudspeaker. Speakers
take turns responding to each other. Because only one
group member can talk at any time, the maximum duration
of a speech turn is limited. The maximum duration is
usually set to 30 seconds. For details of the speech turn
duration for your network, contact your network operator
or service provider.
Warning: Be sure to hold the device in front of you
and not to your ear. The loudspeaker is used to listen.
Continuous exposure to high volume may damage your
hearing.
Phone calls always take priority over push-to-talk
activities.

service providers allow you to use a WAP access point.
Contact your service provider for more information.
If you do not have a WAP connection, you may need to
