communication. When the earpiece 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 push to talk service, you can make or receive
group calls or one-to-one calls. One-to-one calls are calls you make to
only one person.
