Feature and line buttons, located on either side of the screen, give you access to phone features and phone lines.

Feature buttons—Used for features such as Speed dial or Call pickup, and to view your status on another line.

Line buttons—Used to answer a call or resume a held call. When not used for an active call, used to initiate phone functions, such as the missed calls display.

Feature and line buttons illuminate to indicate status.

Green, steady LED—Active call or two-way intercom call

Green, flashing LED—Held call

Amber, steady LED—Privacy in use, one-way intercom call, or logged into a Hunt Group

Amber, flashing LED—Incoming call or reverting call
