Notes on 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.
Modem
This section describes how to connect and disconnect the internal modem
to and from a telephone jack.
Connection to any communication line other than an analog phone line
could cause a computer system failure.
Connect the built-in modem only to ordinary analog phone lines.
Never connect the built-in modem to a digital line (ISDN).
Never connect the built-in modem to the digital connector on a
public telephone or to a digital private branch exchange (PBX).
Never connect the built-in modem to a key telephone system for
residences or offices.
Avoid using your computer modem with the telephone cable connected
during an electrical storm. There may be a remote risk of electric shock
from lightning.
