Environment

Avoid using the deck in the following conditions:

In areas with high temperatures (near a heater, exposed to direct sunlight, for example.)

In areas with extremely low temperatures.

In areas where there is excessive humidity.

In a dusty atmosphere.

In areas where power line voltage fluctuations are severe (in which case the use of a voltage regulator may be advisable).

Cleaning the Tape-Handling Parts

Dirt, dust or particles of the tape's coating can accumu- late 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 oper- ation, follow these steps to clean the tape-handling parts or use a cassette deck cleaning kit (available at your lo- cal 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 cap- stan.

4.When you finish cleaning, press STOP/EJECT and close the cassette compartment door. Then recon- nect power.

TROUBLESHOOTING

If the cassette deck is not working as it should, the follow- ing suggestions might help. If you follow the suggestions in this chart and the cassette deck still does not work properly, contact your local RadioShack store for assis- tance.
