Diskettes; Using The Microphone - Toshiba PT831U-102T97 User Manual

Diskettes

1. Store your diskettes in the container they came in to protect them and
keep them clean. If a diskette is dirty, do not use cleaning fluid. Clean
it with a soft damp cloth.
2. Do not slide back the diskette's protective metal covering or touch the
diskette's magnetic surface. Fingerprints may prevent the diskette
drive from reading data from the diskette.
3. Data may be lost if the diskette is twisted; bent; or exposed to direct
sunlight, extreme heat or cold.
4. Do not place heavy objects on your diskettes.
5. Do not eat, smoke, or use erasers near your diskettes. Foreign
particles inside the diskette's jacket can damage the magnetic
surface.
6. Magnetic energy can destroy the data on your diskettes. Keep your
diskettes away from speakers, radios, television sets and other
sources of magnetic fields.

Using the microphone

Your computer has a built-in microphone that can be used 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 built-in 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.
