5. HANDLING COMPACT DISCS  
This unit has been designed specifically for  
playback of compact discs bearing the  
mark. No other discs can be played.  
Note on compact discs  
Never stick labels on the surface of the compact  
disc or mark the surface with a pencil or pen.  
To remove the compact 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 any solvents such as commercially  
available cleaners, anti-static spray, or thinner to  
clean compact discs.  
Always handle the compact disc by the edges.  
Never touch the surface.  
To remove fingermarks and dust, use a soft cloth,  
and wipe in a straight line from the center of the  
compact disc to the circumference.  
Do not use compact discs that have large scratch-  
es, are misshapen, or cracked, etc. Use of such  
discs will cause misoperation or damage.  
New discs may have some roughness around  
the edges. The unit may not work or the sound  
may skip if such discs are used. Use a ball-point  
pen, etc. to remove roughness from the edge of  
the disc.  
Do not expose compact discs to direct sunlight or  
any heat source.  
Note:  
Do not use commercially available CD protection sheets or discs equipped with stabilizers, etc. These may  
get caught in the internal mechanism and damage the disc.
