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.(Built-in microphone is provided with some models)
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 some wireless
communication devices.
Only some models are equipped with both Wireless LAN and Bluetooth
functions.
■
Do not use the Wireless LAN (Wi-Fi) or Bluetooth functionalities near a
microwave oven or in areas subject to radio interference or magnetic
fields. Interference from a microwave oven or other source can disrupt
Wi-Fi or Bluetooth operation.
■
Turn all wireless functionalities off when near a person who may have a
cardiac pacemaker implant or other medical electric device. Radio
waves may affect pacemaker or medical device operation, possibly
resulting in serious injury. Follow the instruction of your medical device
when using any wireless functionality.
■
Always turn off wireless functionality if the computer is near automatic
control equipment or appliances such as automatic doors or fire
detectors. Radio waves can cause malfunction of such equipment,
possibly resulting in serious injury.
■
It may not be possible to make a network connection to a specified
network name using the ad hoc network function.
If this occurs, the new network(*) will have to be configured for all
computers connected to the same network in order to re-enable
network connections.
* Please be sure to use new network name.
