Notes on CD and DVD discs
❑
Do not drop or bend the disc.
❑
Do not touch the surface of the disc. Fingerprints and dust on the surface of a 
disc may cause reading errors. 
❑
For normal cleaning, hold the disc by its edge and use a soft cloth to wipe the 
surface from the center out.
❑
If the disc is badly soiled, moisten a soft cloth with water, wring it out well, 
and use it to wipe the surface of the disc from the center out. Wipe off any 
remaining moisture with a dry, soft cloth.
❑
Do not use solvents such as benzine, thinner, commercially available 
cleaners or anti-static spray, as they may damage to the disc.
Do not use the Eject PC option in Windows® or press the UNDOCK switch on the 
docking station while writing data to a CD-R or CD-RW. Doing so may severely 
damage your computer.
Do not put your computer into power saving mode while writing data to a CD-R 
or CD-RW disc.
Do not strike or shake the computer while writing data to a disc.
Memory-resident disc utilities, such as the screen saver and virus checker, may 
cause unstable operation or data loss. Deactivate these utilities (if they are 
active) before writing data to a disc.
Always use the AC adapter as the power source for your computer when you are 
writing data to a CD-R or CD-RW. Using battery power may result in data 
transfer failure.
