Using the microphone

You can use the built-in or an external microphone that connects to the
microphone jack to record 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 both Wireless
LAN and Bluetooth 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 802.11b,g and n
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.
