sound, handle the disc as follows.
Handle the disc by its edge. To keep the disc
clean, do not touch the surface.
Do not stick paper or tape on the labeled
surface.
Do not expose the discs to direct sunlight or
heat sources such as hot air-ducts, or leave
them in a car parked in direct sunlight where
there can be a considerable rise in the
temperature inside the car.

On a rainy day or in a very damp area,
moisture may condense on the lenses inside
the CD player. Should this occur, the unit will
not operate properly. In this case, remove the

Maintenance
Fuse replacement
When replacing the fuse, be sure to use one
that matches the amperage described on the
fuse. If the fuse blows, check the power
connection and replace the fuse. If the fuse
blows again after replacement, there may be an
internal malfunction. In such a case, consult
your nearest Sony dealer.
