Operating Basics

You can use the built-in or an external microphone that connects to the 

microphone jack 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 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.

The computer's wireless communication function supports both Wireless 

LAN and Bluetooth devices.
