Handling Cassette Tapes  
6. REMOTE CONTROL  
1. FEATURES  
Using any of the following types of cassette  
tapes can cause malfunctions.  
• Avoid using cassettes of 120 minutes or  
longer. (Such cassettes have extremely thin  
tape, so the tape can become stretched or  
cut.)  
• Periodically play a cleaning cassette in the  
player to clean the head.  
• Keep magnet items like magnets, and iron and  
steel items like screwdrivers away from both  
cassette tapes and the tape head in the player.  
• Do not oil the cassette mechanism.  
• Do not use any cassette tapes with peeling  
labels or deformed cases. Such cassette tapes  
can cause breakdowns.  
• When not using the player, always take the  
cassette out of the mechanism. Exposing a  
cassette to direct sunlight, extreme tempera-  
tures or high humidity can damage the cas-  
sette.
