Important Precautions
Read the following before operating the Disklavier.
Warning
• Do not locate the Disklavier 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 on the Disklavier power cable to a
compatible AC outlet. Failure to do so will present a
fire and electric shock hazard. If the power cable plug
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 power cable. A
damaged power cable is a potential fire and electric
shock hazard. If the power cable runs under a carpet,
make sure heavy objects, including the Disklavier, are
not placed on top of the cable.
• If the power cable is damaged (i.e. cut or a bare wire is
exposed), ask your dealer for a replacement. Using the
Disklavier in this condition is a fire and shock hazard.
• When disconnecting the power cable from an AC
outlet, always pull by 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 top
of the Disklavier.
• Do not try to modify the Disklavier, as this could lead
to fire or electric shock hazard.
• When moving the Disklavier to another location, turn
off the power, remove the power plug from the AC
outlet, and remove all cables connected to external
devices.
Cautions
• Turn off all audio devices when connecting to the
Disklavier. 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 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 is worked extremely hard — that is,
prolonged playback of very “busy” songs — the
Disklavier’s thermal relay may trip. The thermal relay
will automatically reset when the Disklavier has cooled
down.
• If you notice any abnormality — such as smoke, odor,
or noise — turn off the Disklavier immediately, and
remove the power plug from the AC outlet. Consult
your dealer for repair.
