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 

 section for 

precautions on writing to CDs/DVDs.
