Maintenance
• When removing the disc from its case, hold it at
the edge while pressing the center hole lightly.
• Do not touch the shiny surface of the disc, or
bend the disc.
• Put the disc back in its case after use to prevent
warping.
• Be careful not to scratch the surface of the disc.
• Avoid exposure to direct sunlight, extreme
temperature, and moisture.
• Be sure not to use thinners, benzenes, cleaners
for analog records, or other chemical agents.
• Gently dust the cabinet surface with a soft dry
cloth. When the cabinet is excessively dirty,
dampen the cloth with a neutral detergent diluted
with water, wring out the cloth, then wipe the
cabinet with the dampened cloth followed by a
soft dry cloth.
• Do not wipe the cabinet with thinners or
benzenes. Wiping it with these agents may
cause discoloration of the cabinet or removal of
the paint. Do not spray insecticides or other
highly volatile agents onto the cabinet. Do not
leave pieces of rubber or plastic on the cabinet
for a long period.
