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 performance of the cassette player. After 
every 20 hours of tape player operation, follow these steps to 
clean the tape-handling parts or use a cassette deck cleaning kit 
(available at your local RadioShack store).

1. Remove the batteries and disconnect any other power 

source.

2. Open the cassette compartment door and press 

PLAY

 to 

expose the tape-handling parts.

3. Use a cotton swab dipped in denatured alcohol or tape 

head cleaning solution to clean the tape guides, record/
play head, erase head, pinch roller, and capstan.

4. When you finish cleaning, press 

STOP/EJECT

 and close 

the cassette compartment door. Then reconnect power.
