Periodic Maintenance
Compact Disc Player
The accumulation of dust particles on the laser pickup lens may cause skipping or track jump. Use a camera lens brush/blower to blow clean. Do not touch the pickup lens. Fingerprints will also cause the player to malfunction.
Care and Maintenance
Care and Handling of Compact Discs
1.Handle the disc by its edges or center hole. To keep the disc clean, avoid touching the data surface.
2.Data is embedded directly beneath the label, protected only by a thin lacquer layer and is more vulnerable to damage than the bottom. A scratch that penetrates the label will certainly destroy data, whereas a scratch on the bottom can often be overlooked or corrected by the laser pickup.
3.Do not write on the label surface. A ballpoint will damage data; marking pens have solvents that may penetrate the top layer.
4.Do not stick paper or tape on the label surface; this probably won’t hurt the disc but might jam the disc drive.
5.Do not expose a disc to high temperature or humidity for an extended period of time. The disc material will soften at around 200 degrees Fahrenheit. Allow the disc to reach room temperature before playing if it has been subjected to extreme cold.
6.Preventive cleaning is unnecessary and potentially harmful. Clean only when required.
7.Clean a disc with a soft moistened cloth. Pat dry. Wipe the disc from the center out like spokes of a wheel. Never wipe across
a disc as you would an LP record.
8.Never use solvents, commercial cleaners or sprays designed for LP’s. Plain lukewarm water is recommended.
9.Keep discs protected at all times.
Cassette Maintenance & Service Cleaning
The heads, capstan and pinch roller should be cleaned from time to time to prevent buildup of tape oxide, which degrades performance.
1.Remove cassette tape before cleaning.
2.Clean the head of all visible,
Caution: DO NOT scrape the head surface with hard, sharp or abrasive objects. This will permanently damage the heads.
3.Clean the pinch roller by scrubbing the surface of the roller with the moistened swab. Rotate the roller by hand until the entire surface is clean.
4.Clean external case surfaces with a moist, soft cloth. Use only a mild detergent water solution.
Tape Head Demagnetization
It is recommended that the tape heads be demagnetized from time to time. This eliminates residual magnetism which degrades sound reproduction and the recording function.
1.After cleaning the heads and capstan, place the demagnetizer several feet away from the cassette unit and plug it into an AC outlet.
2.Follow the manufacturer’s operating instructions supplied with the demagnetizer.
