Preventing Premature Disc Failure
Keep the disc tray and disc as clean and dust-free as
humanly possible during the record process. DO NOT
touch the recording surface, and do not expose the disc tray
and disc to dust or dirt.
DO NOT BLOW ON THE DISC to remove dust or dirt. To
remove dust from the recording surface use a camera lens
bulb. Be sure to follow the instructions when using the
cloth.
To remove stubborn dirt or grease from the recording sur-
face use only nonabrasive foam-tipped swabs (such as
Chemtronics Foamtips #120) with a small amount of pure,
denatured alcohol. To avoid scratching the recording sur-
face BE SURE TO USE ONLY LIGHT STROKES, begin-
ning at the disc center, pulling directly towards the disc's
outer edge.
Always record in a dust-free environment. If the disc must
be removed from CDR400tx before recording is finished,
store the disc in a clean, dust-free environment.
If a disc tray accumulates dust, DO NOT USE IT FOR
DISC RECORDING. Always use a clean, dust-free tray
for disc recording.
Place CDR400tx on a solid, stable surface, away from
high-traffic areas. The surface must allow CDR400tx to
operate in a level, horizontal position.
Avoid touching or handling CDR400tx when recording.
