TASCAM DV-RA1000 Owner’s Manual
Handling of optical discs
Observe the following:
• Always place discs in the tray with their label fac-
ing upward (discs used in the DV-RA1000 can only
be played on one side).
• To remove a disc from its storage case, press down
on the center of the case, and lift the disc out, hold-
ing it carefully by the edges.
• Finger marks and dust should be carefully wiped
off the disc’s recorded surface with a soft cloth.
Unlike conventional records, the compact disc has
no grooves to collect dust and microscopic debris,
so gently wiping with a soft cloth should remove
most particles.
• Wipe in a straight motion from the inside to the
outside of the disc. Small dust particles and light
stains will have absolutely no effect on reproduc-
tion quality.
• Never use such chemicals as record sprays, anti-
static sprays or fluid, benzine or thinner to clean
compact discs. Such chemicals will do irreparable
damage to the disc’s plastic surface.
• Discs should be returned to their cases after use to
avoid serious scratches that could cause the laser
pickup to “skip”.
• Don’t expose discs to direct sunlight or high
humidity and temperature for extended periods.
Long exposure to high temperature can warp the
disc.
• Only use circular discs. Avoid using non-circular
promotional, etc. discs.
• To keep the laser pickup clean, and don’t touch it.
For the same reason, don’t leave the disc tray
opened unnecessarily.
Additional notes with regard to CD-R and CD-RW discs
There are additional precautions that you should take
when handling CD-R and CD-RW discs, that are dif-
ferent to those that you should take when handling
ordinary CDs.
• Avoid touching the recording (non-label) side of a
disc on which you will be recording. Recording on
a disc requires a cleaner surface than playing back,
and fingerprints, grease, etc. can cause errors in the
recording process.
• CD-R discs are more sensitive to the effects of heat
and ultraviolet rays than ordinary CDs. It is impor-
tant that they are not stored in a location where
direct sunlight will fall on them, and which is away
from sources of heat such as radiators or heat-gen-
erating electrical devices.
• Always store CD-R discs in their “jewel cases” to
avoid dirt and dust accumulating on their surfaces.
• Do not put labels or protective sheets on the discs
and do not use any protective coating spray.
• When labeling CD-R discs, always use a soft oil-
based felt-tipped pen to write the information.
Never use a ball-point or hard-tipped pen, as this
may cause damage to the recorded side.
• Dirty discs may be cleaned using a soft dry cloth
and/or a commercial CD cleaning fluid or ethyl
alcohol. Do not use thinner, gasoline, benzene or
LP cleaning fluid, as these will damage the disc.
• If you are in any doubt as to the care and handling
of a CD-R disc, read the precautions supplied with
the disc, or contact the disc manufacturer directly.
