Protect the Disc
1. To keep the disc clean, please don’t touch the disc’s surface when you are holding it. You should hold
the edge.
2. If the disc is dirty, it will affect the sound quality. Please use the clean and soft cloth to wipe the disc
from inside to outside. Don’t wipe the disc in circular motion.
3. Don’t stick paper on the disc.
4. Don’t place discs in direct sunlight or near or on heat sources.
5. After you have finished with the disc, please place it back in its original case. To avoid warping or
damage, do not stack discs.
6. Don’t play the disc which has flaw or deformation, in case of damaging this player.
7. Clean your discs using only a soft dry cloth. Do not use any chemicals such as benzine, thinner,
antistatic or record sprays as these can damage the disc surface.
