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 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.
