Cleaning the lens

Compact discs

• This system can play back the following discs:

However, continued use of irregular shape discs (heart-shape, octagonal, etc.) can damage the system.

• Remove the disc from its case by holding it at the edges while pressing the case’s 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.
