Note: This feature may not 
be available in your product 
due to your subscription 
(network service).
Push to talk (PTT) over cellular is 
a two-way radio service available 
over a GSM/GPRS cellular network 
(network service). PTT provides direct 
voice communication. To connect, 
press the PTT key.
You can use PTT to have a 
conversation with one person or 
with a group of people having 
compatible devices. When your call 
is connected, the people you are 
calling do not have to answer the 
phone. The participants should 
confirm the reception of any 
communication where appropriate, 
as there is no other confirmation 
whether the recipients have heard 
the call.
To check availability and costs, and 
to subscribe to the service, contact 
your network operator or service 
provider. Roaming services may be 
more limited than for normal calls.
Before you can use the PTT service, 
you must define the required PTT 
service settings. See 
p.
While you are connected to the PTT 
service, you can use the other 
functions of the phone. The PTT 
service is not connected to 
traditional voice communication; 
therefore many of the services 
available for traditional voice calls 
(for example, voice mailbox) are not 
available for PTT communication.

automatically joined to the active 
channels, and if you have selected a 
contact, contact groups, or channel 
as the default action for the PTTkey, 
then the name of the selected item is 
displayed in the standby mode.
