Follow the recommended cleaning schedule:
- Clean the cassette player every 15 hours for the best performance.
- Clean the cassette player every 50 hours in order to prevent
damage to the tape head.
Clean the following 2 parts on the tape player:
Leave the tape player in the vehicle. You can access the components
through the tape door. Perform this service at least every 50 hours
of cassette operation. After 50 hours of tape play, CLN (Clean) appears
on the display as a reminder. Although the system will still function when
this message is displayed, the following conditions may occur until the head
and the capstan are cleaned:
| • | Damage to the cassette tapes |
After cleaning the cassette tape player, press and hold EJECT for 5 seconds
in order to reset the CLN indicator. The radio displays - - - in order to
show that the clean feature has been reset.
Failure to clean the cassette player regularly may cause the following
conditions:
| • | Damage to the cassettes |
| • | Damage to the mechanism |
Keep the cassette tapes correctly stored in their plastic cases away
from the following conditions:
Failure to correctly store the cassette tapes may cause the following
conditions:
| • | Improper operation of the cassette tapes |
| • | Premature failure of the tape player |
The cassettes are subject to wear. The sound quality may degrade over
time.
Before servicing a tape player, verify that the following conditions
exist:
| • | The cassette tape is in good condition. |
| • | The tape player is clean. |
Clean the tape player at least after every 50 hours of use in
order to provide optimum performance. The radio displays CLN as a reminder
every 50 hours. If a reduction in the sound quality occurs, regardless
of when the tape player was last cleaned, play a different cassette tape in
order to see if the tape or the tape player is at fault. If the second cassette
tape results in no improvement in sound quality, clean the tape player.
Use a scrubbing action, non-abrasive cleaning cassette (part of J 39916-A
) for proper tape player
cleaning. This cleaner is a wet-type cleaning system. The wet-type cleaning
system uses a cleaning cassette with pads. The pads scrub the tape head as
the hubs of the cleaner cassette turn.
If you use this type of cleaner, the following conditions may occur:
| • | The radio displays an error. |
These conditions are normal and is the result of an added feature in
the tape player that detects broken tapes.
If an error occurs, insert the cleaning cassette at least 3 times
in order to thoroughly clean the tape player. You can also use a non-scrubbing
action, wet-type cleaner. This type of cleaner uses a cassette with a fabric
belt which cleans the tape head. This type of cleaning cassette will not cause
an error, but may not clean the tape player as thoroughly as the scrubbing
type cleaner.
