Operating Basics
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 media drive
The text and illustrations in this section refer primarily to the optical CD-
ROM drive. However, operation is the same for all other optical media
drives. The full-size drive provides high-performance execution of CD-
ROM-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-ROM
operation. When the computer is accessing a CD-ROM, an indicator on the
drive glows.
If you have a DVD Super Multi drive, refer also to the Writing CD/DVDs with
the DVD Super Multi drive supporting DVD±R Double layer section for
precautions on writing to CDs/DVDs.
