Improper disc storage:
You can damage discs if you store them in the following places;
•Areas exposed to direct sunlight
•Humid or dusty areas
•Areas directly exposed to a heat outlet or heating appliance
Handling precautions:
•Do not write on the label side with a bail-point pen or other writing
utensils.
•Do not use record cleaning sprays, benzine, thinner, static electric¬
ity prevention liquids or any other solvent.
•Do not soil with fingerprints.
