Maintenance - Sony Discman D-303 Operating Instructions Manual

Maintenance
Cleaning the casing
Cleaning the casing with a soft cloth
slightly moistened with water or mild
detergent solution. Do not use any type
of abrasive pad, scouring powder or
solvent such as alcohol or benzine.
Cleaning the lens
If you have accidentally touched the lens
with a dirty finger or if the dust on the
lens prevents the unit from operating
properly, open the disc compartment lid
and clean the lens.
To remove dust
Blow on the lens a few times with a
commercially available blower, brush the
dust away in the direction of the arrow,
then blow on the lens again.
Cleaning the headphone plug
Keep the plug of your headphone clean
to obtain the optimum sound. Wipe it
with a dry, soft cloth.
If the unit still does not function properly,
please consult your nearest Sony dealer.
Notes on compact discs
Do not expose the disc to direct sunlight
or heat sources such as hot air ducts,
nor leave it in a car parked in direct
sunlight as there can be a considerable
rise in the temperature inside the car.
A scratch or other contamination (finger
prints, etc.) on the disc may cause
unstable play.
Before playing, clean the disc with the
optional cleaning cloth.
Wipe the disc from the center out.
Do not use solvents such as benzine,
thinner, commercially available cleaners
or antistatic spray intended for analog
discs.
After playing, store the disc in its case.
