6. If your CD/DVDs become dusty or dirty, wipe them with a clean dry
cloth. Wipe from the center out, do not wipe in a circular direction
around the CD/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
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
Some models are optional equipped with a internal micorphone.
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.
