Operating Basics
Using the microphone
Your computer has 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.(Built-in microphone
is provided with some models)
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.
