Cassette - Poor Sound Quality/Loss of Channel/Jamming

CASSETTE TAPE PLAYER MAINTENANCE
All Nissan vehicles equipped with cassette tape players
In normal use, the playback head, capstan and rollers of any cassette tape player will attract dirt or residues from the tape material each time a cassette is
played. This causes a deterioration of sound quality (i.e., distortion, reduced frequency response, and reduced clarity). If residues and dirt are not
removed, loss of channel(s) or "tape eating" may occur. In order to help your customers to avoid these incidents and ensure optimum performance from
their cassette tape players, please advise them of the need to perform the following maintenance procedures:
Use a cassette cleaning kit to clean the cassette tape player (specifically the tape head and capstan rollers) after every 30 hours of play or once a month,
whichever comes first. You may use the Nissan Cassette Deck Cleaning System, P/N 999U2-AD010 or equivalent. Be careful to follow the kit usage
CASSETTE TAPE CARE GUIDELINES:
Before turning off the radio, eject the cassette being played. Allowing the tape mechanism to stop while a tape is engaged can damage the tape,
pinch roller or capstan. After turning off the radio, do not leave the tape in the cassette door pathway.
Use tapes which are 90 minutes or less in play time.
Use protective plastic cases to store cassettes when not in use. This will prevent them from unwinding and collecting dust.
Protect tapes from extreme heat, direct sunlight, extreme cold, and from foreign material such as liquids or sticky substances. Discard damaged or
Do not use tapes that are more than 5 years old. Older tapes suffer from stretch and increased tape residue.
NOTE: If your customer complains of deterioration of sound quality, loss of channels(s) or "tape eating," please clean the cassette tape player using the
Cassette Deck Cleaning System as described above. In most cases, this procedure will return the cassette deck to full efficiency.
