3 Knowing the main features of your phone The Plantronics P540-M is composed of a display, keypad, and presence light. This section provides an overview of these features and the general tasks that they perform. The face of the phone is composed of a display, keypad, and presence light. Display Your phone has a two-line display that shows your name and date on the first line, and status and time on the second line when you are signed in to Microsoft Office Communicator. Information in the display is shown in the language currently set for Microsoft Office Communicator, except for the date and time. The date and time follow the operating system's regional setting. The display backlight is ON when any of the following conditions exist: • You are on a call. • You are changing the phone settings by using the keypad. For example, you are changing Device Settings by pressing "5." • Microsoft Office Communicator is interacting with the phone. For example, Microsoft Office Communicator is sending contact information about an incoming call. • An application on your computer is streaming audio to/from the phone or has one or more audio interfaces selected. The display backlight turns OFF after 30 seconds of inactivity. For more information about the display, see "Understanding the display" later in this document. For more information about language settings, see "Multilingual User Interface Package (MUI)" later in this document. Warning The display is not a touch screen display. Pushing down on the display can permanently damage the display. Keypad The keypad provides quick access to common functionality in addition to the regular dialing function. Redial Calls the last number dialed. This button dials the last number called, even if that last number did not connect. If you called a contact by using Microsoft Office Communicator and also called a different contact by using the phone, the last number that was called in sequence will be redialed. The information about the last number called is stored in the computer that is running Microsoft Office Communicator. If you disconnect the phone and then connect it to another computer that is also running Microsoft Office Communicator, and you press the Redial button, the phone will redial the last number called according to the second computer to which you just connected the phone. If there is no previously redialed number, pressing the Redial button will not start any action and there will be no message on the display. Redial is the upper-left button on the keypad. Flash Puts a call on hold. If there is an incoming call while you are in another call, pressing the Flash button puts the first call on hold and answers the second call. When you have multiple calls, at any time, one call will always be active. The calls will be toggled in a circle of last active call every time that you press the Flash button. You can put all these calls on hold at the same time only by using Microsoft Office Communicator. Plantronics P540-M User Guide 6
