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.
