CLEANING THE TAPE- HANDLING PARTS

Dirt, dust or particles of the tape’s coating can accumulate on the tape heads and other parts that the tape touches. This can greatly reduce the cassette player’s performance. To prevent noise and poor high- frequency response, clean the cas- sette player’s tape-handling parts after every 20 hours of use. Your local Ra- dioShack store sells a wide selection of cassette deck cleaning supplies.

1.Turn off the system, then unplug its power cord.

2.Press . The cassette com- partment door opens.

3.Press on the deck to expose the tape-handling parts.

4.Use a cotton swab dipped in de- natured alcohol or tape head cleaning solution to gently clean the record/playback head, pinch roller, capstan, tape guides, and erase head.
