Using The Microphone; Using The Internal Modem - Toshiba Portege M100 User Manual

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.
Since your computer has a built-in microphone and speakers, "howling"
may be heard under certain conditions. Howling occurs when sound from
the speakers is picked up in the microphone and amplified back to the
speakers, which amplifies it again to the microphone.
This howling 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 speakers (throughput) and the
speakers volume is too loud or too close to the microphone. You can
control throughput by adjusting the volume of your speakers or through
the Mute function.
To adjust the volume or activate Mute, click start, point to All Programs,
point to Accessories, point to Entertainment and click Volume Control.
In the Master Volume panel, you can use the slide bars to adjust the
volume level or click Mute at the bottom of the panel.
