Cleaning Intervals
Clean the cassette tape player every 15 hours of operation for optimum performance. After you clean the player, press and hold the EJECT button for five seconds to reset the CLEAN indicator. The radio will display - to show that the indicator has been reset.
As a minimum clean the cassette tape player after 50 hours of playing time. This will prevent damage to the cassette tape player mechanism. The radio may display CLN, CLEAN or CLEAN TAPE (depending on the family of radio being used), if equipped with the Clean Tape Indicator Feature. This indicates that you have used the tape player for 50 hours without resetting the tape clean timer. If this message appears on the display, clean the cassette tape player. The player will still play tapes, however the player should be cleaned as soon as possible in order to prevent damage to the tapes and/or the player.
Cassettes are subject to wear and the sound quality may degrade over time. If you notice a reduction in sound quality, play a different cassette. A new cassette will indicate whether the tape or the tape player is at fault.
If the sound quality does not improve when the second tape is played, clean the cassette player. Perform this step regardless of when you last cleaned the cassette player.
If a noticeable improvement is not achieved after cleaning the player, remove the radio assembly for repair.
