Using the microphone

Some models are equipped with a built-in microphone that can be used to

record monaural sounds into your applications. It can also be used to issue

voice commands to applications that support such functions.
Since your computer has a built-in microphone and speaker, “feedback”

may be heard under certain conditions. Feedback occurs when sound from

the speaker is picked up in the microphone and amplified back to the

speaker, which amplifies it again to the microphone.
This feedback occurs repeatedly and causes a very loud, high-pitched

noise. It is a common phenomenon that occurs in any sound system when

the microphone input is output to the speaker (throughput) and the speaker

volume is too loud or too close to the microphone. You can control

throughput by adjusting the volume of your speaker or through the Mute

function in the Master Volume panel. Refer to your Windows documentation

for details on using the Master Volume panel.
