RESTORING TAPE TENSION AND SOUND QUALITY
After you play a cassette tape a few times, the tape might become tightly
wound on the reels. This can cause playback sound quality to deteriorate.
To restore the sound quality, fast-forward the tape from the beginning to
the end of one side, then completely rewind it. Then loosen the tape
reels by gently tapping each side of the cassette's outer shell on a flat
surface.
CAUTION: Be careful not to damage the cassette when tapping it. Do not
touch the exposed tape or allow any sharp objects near the
cassette.
REPLACING A FUSE
If the clock resets or stored stations are lost when the ignition is off,
you might need to replace the yellow clock memory wire's fuse. Use a
standard 1-1/4 inch (30 mm) 12 amp fuse, such as RSU No. 12019410 (a spare
fuse is supplied).
If the stereo does not operate, you might need to replace the red power
lead wire's fuse. Use a standard 1-1/4 inch (30 mm) 0.5 amp fuse, such as
Cat. No. 270-1003 (a spare fuse is supplied).
CAUTION: Make sure you replace a fuse only with another fuse of the same
rating.
Follow these steps to check and replace each fuse.
1. Disconnect the cable from the vehicle's negative (-) battery terminal.
2. To open a fuse holder, pull the latches apart until it opens. Then,
to remove the fuse, gently pull the fuse off of both fuse clips inside
the fuse holder.
3. If the fuse is blown, replace it with a fuse of the same rating.
4. Reassemble the fuse holder by placing the wires and the fuse clips
back inside the holder, then squeeze it together until it snaps shut.
5. Reconnect the cable to the vehicle battery's negative (-) terminal.
6. Reset your stereo's clock and memory settings.
