■ Make and receive a PTT call
Set the phone to use the loudspeaker or ear piece for PTT
communication. When the ear piece is selected, you can 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 PTT 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 PTT key. Talking is allowed on a first-come,
first-served basis. When someone stops talking, the first person to press
the PTT key can talk next.
