PRV-9000 Operating Instructions
11.4 Disc-Handling
Guidelines
When holding discs of any type, avoid leaving fingerprints, smears or scratches
on the recording surface. Hold the disc by the edges or supported from the
center hold.
Avoid scratching the labeling side of the disc as well as the recording side.
Although not as fragile as the recording layer, scratches can still affect the media.
To remove fingerprints and dust, use a cloth soaked in alcohol or a commercially
available CD/DVD disc cleaning material to wipe away smudges. Never use
other chemicals to clean a disc. Do NOT wipe with circular strokes. Wipe lightly
from the center out to the edge using straight stokes.
Cracked or warped discs may damage the recorder. If a disc breaks inside of the
unit, pieces are likely to strike the optics.
When storing discs, place carefully in a jewel-case or disc jacket. Avoid storing
discs in locations subject to temperature extremes, moisture and direct sunlight.
To avoid warping, avoid stacking discs. Discs are best maintained when stored
upright.
Do NOT glue or use stickers on a DVD disc. Labels may unbalance the disc
causing it to fail or even to break. Label glue may slip in melt in extreme cases.
Use the appropriate marking pen to write on the labeling side of the disc.
Pencils, ballpoint pens and other sharp-tipped writing instruments may damage
the reflectivity of a disc. Refer to your place of purchase for assistance.
Non-standard disc shapes are unusable on this device. These non-standard
shapes include hearts, diamonds, polygons, etc.
