TASCAM DV-RA1000HD

Environmental considerations
The unit may be used in most areas, but to maintain top
performance, and prolong operating life, observe the
following environmental conditions:
Avoid exposing it to extremes of temperature and
humidity and avoid mechanical shocks and vibration.
Keep the unit away from strong magnetic fields (TV
sets, computer monitors, large electric motors, etc.).
The nominal temperature should be between 5°C and
35°C (41°F and 95°F).
Relative humidity should be 30 to 90 percent.

As the unit may become hot during operation, always
leave sufficient space above the unit for ventilation.
Do not install this unit in a confined space such as a
bookcase, and do not put anything on top of the unit.
Avoid installing this unit on top of any heat-generat-
ing electrical device such as a power amplifier.
The voltage supplied to the unit should match the
voltage as printed on the rear panel. If you are in any
doubt regarding this matter, consult an electrician.
Make sure that the unit is mounted in a level position
for correct operation.

Observe the following:
Always place discs in the tray with their label facing
upward (discs used in the DV-RA1000HD 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.
Figure 1.2: Handling of discs
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 out-
side of the disc. Small dust particles and light stains
will have absolutely no effect on reproduction qual-
ity.

Never use such chemicals as record sprays, antistatic
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 humid-
ity 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.
Figure 1.4: Avoid using non-circular discs
To keep the laser pickup clean, and don’t touch it.
For the same reason, don’t leave the disc tray opened
unnecessarily.
Music discs with copy control, a copy-protection
system, have been released form several record
companies in an attempt to protect the copyright.
Since some of these discs do not comply with the
CD specifications, they may not be playable on the
DV-RA1000HD.
