Operating Basics Floppy disks 1. Store your floppy disks in the container they came in to protect them and keep them clean. If a floppy disk is dirty, do not use cleaning fluid. Clean it with a soft damp cloth. 2. Never open the shutter or touch the magnetic surface of your floppy disk. You could permanently damage it and lose data. 3. Always handle floppy disks with care, to prevent the loss of stored data. Always apply the floppy disk label in the correct location. Never apply a new label on top of an existing one. The label could come loose and damage the floppy drive. 4. Never use a pencil for writing on a floppy disk label. Pencil lead dust could cause a system malfunction. Always use a felt-tipped pen. When writing a title on a label, first write on the label, then apply the label to the floppy disk. 5. Never put a floppy disk in a location where water or other liquid may contact it or where it is excessively damp. It could cause data loss. Never use a wet or damp floppy disk. It could damage the floppy disk drive or other devices. 6. Data may be lost if the floppy disk is twisted; bent; or exposed to direct sunlight, extreme heat or cold. 7. Do not place heavy objects on your floppy disks. 8. Do not eat, smoke, or use erasers near your floppy disks. Foreign particles inside the floppy disk's jacket can damage the magnetic surface. 9. Magnetic energy can destroy the data on your floppy disks. Keep your floppy disks away from speakers, radios, television sets and other sources of magnetic fields. Sound System 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, "howling" may be heard under certain conditions. Howling 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 howling 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. 4-26 User's Manual
