Webcam

Webcam
Your device includes a webcam with integrated microphone.
Depending on the software used, you can use your webcam to take pictures,
record video clips or take part in web chats.
The webcam has its own status indicator. The indicator lights up when the webcam is active.
• The picture quality depends on the lighting conditions and the software being used.
• You can only operate the webcam with a particular application (e.g. an Internet telephony
program or a video conferencing program which supports a webcam).
• When using the webcam, the notebook base must not wobble.
• The webcam automatically adjusts itself to the current light level. For this reason
the LCD display may flicker while the light level is adjusted.

can be found in the help function of the program using the webcam.
