23
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 temperature
inside the car.
Before playing, clean the discs with an optional
cleaning cloth. Wipe each disc from the center
out.
Do not use solvents such as benzine, thinner,
commercially available cleaners, or antistatic
spray intended for analog discs.
Note on moisture condensation
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
disc and wait for about an hour until the
moisture evaporates.
When you play 8 cm (3 in.) CDs
Use the optional Sony compact disc single
adapter (CSA-8) to protect the CD player from
damage.
Maintenance
Fuse replacement
When replacing the fuse, be sure to use one
matching the amperage rating started on the
original 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.
Warning
Never use a fuse with an amperage rating
exceeding the one supplied with the unit as
this could damage the unit.
Cleaning the connectors
The unit may not function properly if the
connectors between the unit and the front
panel are not clean. In order to prevent this,
open the front panel by pressing (RELEASE),
then detach it and clean the connectors with a
cotton swab dipped in alcohol. Do not apply
too much force. Otherwise, the connectors may
be damaged.
