V
CAUTION!
Only use CDs/DVDs/BDs that are in perfect condition, in order to
●
prevent data loss, equipment damage and injury.
Check each CD/DVD/BD for damage, cracks, breakages etc. before
●
inserting it in the drive.
Note that any additional labels applied may change the mechanical
properties of a CD/DVD/BD and cause imbalance and vibrations.
Damaged and imbalanced CDs/DVDs/BDs can break at high drive
speeds (data loss).
Under certain circumstances, sharp CD/DVD/BD fragments can
pierce the cover of the optical disk drive (equipment damage) and can
fly out of the device (danger of injury, particularly to uncovered body
parts such as the face or neck).
High humidity and airborne dust levels are to be avoided. Electric
●
shocks and/or server failures may be caused by liquids such as
water, or metallic items, such as paper clips, entering a drive.
Shocks and vibrations are also to be avoided.
●
Do not insert any objects other than the specified CDs/DVDs/BDs.
●
Do not pull on, press hard, or otherwise handle the CD/DVD/BD tray
●
roughly.
Do not disassemble the optical disk drive.
●
Before use, clean the optical disk tray using a soft, dry cloth.
