Important information
Keep the CDs/DVDs/BDs away from heat sources.
●
Do not bend or place heavy objects on CDs/DVDs/BDs.
●
Do not write with ballpoint pen or pencil on the label (printed) side.
●
When a CD/DVD/BD is moved from a cold place to a warm place,
●
moisture condensation on the CD/DVD/BD surface can cause data
read errors. In this case, wipe the CD/DVD/BD with a soft, dry cloth
then let it air dry. Do not dry the CD/DVD/BD using devices such as a
hair dryer.
To avoid dust, damage, and deformation, keep the CD/DVD/BD in its
●
case whenever it is not in use.
Do not store CDs/DVDs/BDs at high temperatures. Areas exposed to
●
prolonged direct sunlight or near heating appliances are to be
avoided.
I
You can prevent damage from the optical disk drive and the
CDs/DVDs/BDs, as well as premature wear of the disks, by observing
the following suggestions:
– Only insert disks in the drive when needed and remove them after
use.
– Store the disks in suitable sleeves.
– Protect the disks from exposure to heat and direct sunlight.
Laser information
The optical disk drive complies with IEC 60825-1 laser class 1.
V
CAUTION!
The optical disk drive contains a light-emitting diode (LED), which under
certain circumstances produces a laser beam stronger than laser
class 1. Looking directly at this beam is dangerous.
Never remove parts of the optical disk drive casing!
