DVD. If necessary, use a cloth dampened in water or a neutral cleaner. Do
not use benzine, thinner or similar cleaner.
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 dis-
kette’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 sun-
light, 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.
