Plantronics P540-M User Guide 6
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.
