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.

Using the optical disc drive

The text and illustrations in this section refer primarily to the optical disk 

drive. However, operation is the same for all other optical media drives. The 

full-size drive provides high-performance execution of CD/DVD/HD 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/HD 

DVD operation. When the computer is accessing a CD/DVD/HD DVD, an 

indicator on the drive glows.
Refer also to the 

 section for precautions on writing to CD/DVD/HD 

DVD.
