- Do not expose discs to direct sunlight or place them in dirty, dusty or damp areas. Do not store near the heater vent of your car, or
leave on the seats or dashboard.
2) Disc cleaning
Use a dry soft cloth to wipe the surface. If the disc is quite dirty, use a soft cloth, lightly dampened with isopropyl alcohol. Never use
solvents such as benzene, thinner or conventional record cleaners as they may damage the surface of the disc.
5.4 Precautions when using new discs
A new disc may have rough edges. It will sometimes be necessary to remove these rough surfaces with a ballpoint pen or pencil as
shown in the illustration.
