■ Make and receive a PTT call
Set the phone to use the loudspeaker or earpiece for PTT
communication. When the earpiece is selected, use the phone normally
by holding it to your ear.
Warning: Do not hold the device near your ear when the loudspeaker is
in use, because the volume may be extremely loud.
When connected to the PTT service, you can make or receive channel
calls, group calls, or one-to-one calls. One-to-one calls are calls you
make to only one person.
Press and hold the volume up key the entire time you are talking, and
hold the phone in front of you so that you can see the display. When you
are finished, release the volume up key. Talking is allowed on a first
come, first served basis. When someone stops talking, the first person to
press the key used for PTT can talk next.
