Troubleshooting
To get the best performance of the unit, keep your discs, tapes, and mechanism clean.
Handling discs
•
Remove the disc from its case by holding it at
the edge while pressing the center hole lightly.
• Do not touch the shiny surface of the disc,
or bend the disc.
• Put the disc back in its case after use to
prevent warping.
• Be careful not to scratch the surface of the
disc when placing it back in its case.
• Avoid exposure to direct sunlight,
temperature extremes, and moisture.
To clean the disc
Wipe the disc with a soft cloth in a straight
line from center to edge.
DO NOT use any solvent — such as conventional
record cleaner, spray, thinner, or benzine — to
clean the disc.
Handling cassette tapes
• If the tape is loose in its cassette, take up
the slack by inserting a pencil in one of the
reels and rotating.
• If the tape is loose, it may get stretched,
cut, or caught in the cassette.

tape:
