Handling Discs
Handling
•   New discs may have some roughness 
around the edges. If such discs are used, 
the player may not work or the sound may 
skip. Use a ball-point pen or the like to 
remove any roughness from the edge of 
the disc.
•   Never stick labels on the surface of the disc 
or mark the surface with a pencil or pen.
•   Never play a disc with any cellophane tape 
or other glue on it or with peeling off marks. 
If you try to play such a disc, you may not 
be able to get it back out of the player or it 
may damage the player.
•   Do not use discs that have large scratches, 
are misshapen, cracked, etc. Use of such 
discs may cause misoperation or damage.
•   To remove a disc from its storage case, 
press down on the center of the case and 
lift the disc out, holding it carefully by the 
edges.
•   Do not use commercially available disc 
protection sheets or discs equipped with 
stabilizers, etc. These may damage the 
disc or cause breakdown of the internal 
mechanism.
Storage
•   Do not expose discs to direct sunlight or 
any heat source.
•   Do not expose discs to excess humidity or 
dust.
•   Do not expose discs to direct heat from 
heaters.
Cleaning
•   To remove ngermarks and dust, use a soft 
cloth and wipe in a straight line from the 
center of the disc to the circumference.
•   Do not use any solvents, such as 
commercially available cleaners, anti-static 
spray, or thinner to clean discs.
•   After using special disc cleaner, let the disc 
dry off well before playing it.
On Discs
