Operating Basics

Using the microphone

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.

Wireless communications

The computer's wireless communication function supports Wireless LAN devices.

Wireless LAN

The Wireless LAN is compatible with other LAN systems based on Direct Sequence Spread Spectrum/Orthogonal Frequency Division Multiplexing radio technology that complies with the IEEE802.11 Wireless LAN standard.

■Frequency Channel Selection of 2.4GHz for 802.11bg or n 2.0

■Roaming over multiple channels

■Card power management

■Wired Equivalent Privacy (WEP) data encryption based on an 128-bit encryption algorithm

■Wi-Fi Protected Access™ (WPA™) support

■Advanced Encryption Standard (AES) data encryption

■The transmission speed over the wireless LAN, and the distance over which the wireless LAN can reach, may vary depending on surrounding electromagnetic environment, obstacles, access point design and configuration, client design and software/hardware configurations. The transmission rate described is the theoretical maximum speed as specified under the appropriate standard - the actual transmission speed will be lower than the theoretical maximum speed.

■To enable or disable wireless communication, use the Hot Key FN+F8. For more information see the Hot keys section in Chapter 5.
