[Push-to-talk feature]
Members of a Broadcast Mode call can enable their own ability to speak by pressing any of their dial keys
during the Broadcast Mode announcement. This feature can be disabled through system programming.
[Example]
A central operator can make a Broadcast Mode announcement to multiple PS users working throughout a
building. All the PS users will hear the announcement through their PSs' hands-free speaker. Then, any PS
user can use push-to-talk to respond to the request, and the response is heard by all broadcast members. This
makes it easy to assign and coordinate tasks with multiple staff members who frequently move throughout a
building.

During a conference group call, the caller can restrict or allow members' ability to speak, and can remove
members from the call using the following buttons. These buttons will function irrelevant of the Conference
Group Call mode. Pressing the other buttons during the conversation will be ignored.
