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
to expose the tape-handling parts.
PLAY
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
close the cassette compartment door. Then recon-
nect power.
