Beam Forming feature

A built-in dual array digital microphone is mounted at the top of the display. Whereas a conventional single-element microphone captures sounds from all around, the built-in dual array digital microphone is designed to capture the sound from an exceptionally limited angle, through the combination of a specialized microphone array with a capability of digital signal processing. Therefore the microphone captures sounds from the area in front of the system clearly, but blocks out almost all the sounds from outside the capturing range. Thus the speech of a user sitting in front of the system is input to the system without interference from noise in the surrounding area. To record your speech most clearly, you should speak from directly in front of the computer.

Configuring for sound recording

To configure the microphone for optimized sound recording, open the SmartAudio window as follows:

For Windows 7 and Windows Vista: Click Start ➙ Control Panel ➙ Hardware and Sound ➙ SmartAudio. The SmartAudio window opens.

For Windows XP: Click Start ➙ Control Panel. Switch to Classic View and click SmartAudio. The SmartAudio window opens.

Using an integrated camera

If your computer has an integrated camera, when you press Fn+F6 to open the Communications settings window, the camera will be launched and the green camera-in-use indicator will turn on automatically. In the Communications settings window, you can preview your video image and take a snapshot of your current image.

You can also use the integrated camera with other programs that provide features such as photographing, video capturing, and video conferencing. To use the integrated camera with other programs, open one of the programs and start the photographing, video capturing, or video conferencing function. Then, the camera will start automatically and the green camera-in-use indicator will turn on. For more information about using the camera with a program, refer to the documentation that came with the program.

If you do not want the camera to be launched automatically when you press Fn+F6 or when you use a program, press Fn+F6 to open the Communications settings window and click the Hide my camera image button to disable the camera.
