Important Precautions
Read the following before operating the Disklavier control unit.
■ Warnings
• Do not locate the Disklavier control unit in a
place subject to excessive heat, low
temperatures, or direct sunlight. This could be a
fire hazard and may damage the finish and
internal parts.
• Excessive humidity or dust can lead to fire or
electric shock.
• Connect the plug of the AC adaptor to a
compatible AC outlet. Failure to do so will
present a fire and electric shock hazard. If the
AC adaptor is not compatible with your AC
outlet, consult your dealer.
• Do not plug several devices into the same AC
outlet. This can overload the AC outlet, and lead
to fire and electric shock hazard. It may also
affect the performance of some devices.
• Do not place heavy objects on the AC adaptor
cable. A damaged cable is a potential fire and
electric shock hazard. If the cable runs under a
carpet, make sure heavy objects are not placed
on top of the cable.
• If the AC adaptor cable is damaged (i.e. cut or a
bare wire is exposed), ask your dealer for a
replacement. Using the Disklavier control unit in
this condition is a fire and shock hazard.
• When disconnecting the AC adaptor cable from
an AC outlet, always pull from the plug. Never
pull the cable. Damaging the cable in this way is
a potential fire and electric shock hazard.
• The cover of the unit should be removed only by
qualified service technicians.
• Do not place liquid containers such as vases,
potted plants, glasses, cosmetic bottles,
medicines, etc., on the Disklavier control unit.
• Do not try to modify the Disklavier control unit,
as this could lead to fire or electric shock hazard.
• When moving the Disklavier control unit to
another location, turn off the power, remove the
AC adaptor from the AC outlet, and remove all
cables connected to external devices.
• Use only the specified AC adaptor. Use of other
AC adaptors may result in damage, overheating,
or fire.

■ Cautions
• Turn off all audio devices when connecting to
the Disklavier control unit. Refer to the user's
guide for each device. Use the correct cables
and connect as specified.
• Set the volume level on all the devices to
minimum before applying power.
• Do not play the Disklavier control unit at a high
volume for extended periods; you may damage
your hearing. This is especially important when
using headphones. If you think your hearing
ability is impaired, consult your doctor.
• If the Disklavier control unit is worked extremely
hard — that is, prolonged playback of very
"busy" songs — the thermal relay of the
Disklavier control unit may trip. The thermal
relay will automatically reset when the Disklavier
control unit has cooled down.
• If you notice any abnormality — such as smoke,
odor, or noise — turn off the Disklavier control
unit immediately, and remove the AC adaptor
from the AC outlet. Consult your dealer for
repair.
• If a foreign object or water gets inside the
Disklavier control unit turn it off immediately, and
remove the power plug from the AC outlet.
Consult your dealer.
• If you plan not to use the Disklavier control unit
for a long period of time (such as when you are
on vacation), disconnect the AC adaptor from
the AC outlet.
• Always remove the AC adaptor from the AC
outlet before cleaning the Disklavier control unit.
Leaving the AC adaptor connected presents a
risk of electric shock.
• Do not use benzene, thinner, cleaning
detergent, or a chemical cloth to clean the
Disklavier control unit.
• Do not place metal objects with rubber feet on
the Disklavier control unit. The color and finish of
the Disklavier control unit can be damaged.
• Do not place heavy objects on the Disklavier
control unit. Doing so can damage the Disklavier
control unit.
• Use a soft, dry cloth to clean the Disklavier
control unit. However, if you discover a stain,
carefully use a soft damp cloth to remove it.
