IMPORTANT NOTES
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY”
on pages 2–4, please read and observe the following:
Power Supply
301
• Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
307
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
Placement
351
• Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this
unit; or move it farther away from the source of inter-
ference.
352
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
354a
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.
355
• To avoid possible breakdown, do not use the unit in a wet
area, such as an area exposed to rain or other moisture.
356
• Do not allow rubber, vinyl, or similar materials to remain
on the piano for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.
357
• Do not put anything that contains water (e.g., flower
vases) on the piano. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans, etc., near the
unit. Swiftly wipe away any liquid that spills on the unit
using a dry, soft cloth.
• During operation, this device must be placed at a
distance of no less than 50 cm from any walls.
• Do not allow objects to remain on top of the unit.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to
wipe the unit thoroughly with a soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
(add)
• For routine care of the carpeted area, use a brush with
stiff bristles.
Additional Precautions
553
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its
jacks and connectors. Rough handling can lead to
malfunctions.
556
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
557
• A small amount of heat will radiate from the unit during
normal operation.
558a
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
559
• When you need to transport the unit, package it in the
box (including padding) that it came in, if possible.
Otherwise, you will need to use equivalent packaging
materials.
• At least two persons are required in order to safely lift the
unit when it is to be moved.
