Do not contaminate the CD/DVD/BD surface with fingerprints, oil,
●
dust, etc. If dirty, clean with a soft, dry cloth, wiping from the center to
the edge. Do not use benzene, thinners, water, record sprays,
antistatic agents, or silicone-impregnated cloth.
Be careful not to damage the CD/DVD/BD surface.
●
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.
●
Do not attach stickers or similar to the label side. Doing so may cause
●
rotational eccentricity and abnormal vibrations.
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 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 drive complies with IEC 60825-1 laser class 1.
V
CAUTION!
The optical 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 drive casing!
