Operating Basics
Using the microphone (optional)
Some models in this series 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.(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.
Using the optical disc drive
The full-size drive provides high-performance execution of CD/DVD-based
programs. You can run either 12 cm (4.72") or 8 cm (3.15") CDs without an
adaptor. An ATAPI interface controller is used for CD/DVD operation. When
the computer is accessing a CD/DVD, an indicator on the drive glows.
Refer also to the
Writing CD/DVD with the DVD Super Multi drive
supporting DVD±R DL section for precautions on writing to CD/DVD.
