Important Notes
In addition to the “USING THE UNIT SAFELY” listed on page 6–8, please observe the following cautions.
Power Supply
301
Do not connect this device to the same electrical outlet as an
inverter-controlled device such as a refrigerator, microwave
oven, or air conditioner, or a device that contains an electric
motor. Depending on how the other device is used, power
supply noise could cause this device to malfunction or produce
noise. If it is not practical to use a separate electrical outlet,
please connect this device via a power supply noise filter.
307
Before you make connections, you must switch off the power
on all devices to prevent malfunction and/or speaker damage.
308
When you turn off the power, the screen and indicators of this
device will go dark, but this does not mean that the main power
supply is completely disconnected. If you need to completely shut
off the power supply, turn off the power switch of this device and
then unplug it from the AC outlet. Connect this device to an AC
outlet that is as close and accessible as possible.
Location
351
If this device is placed near devices that contain large
transformers, such as power amps, hum may be induced in
this device. If this occurs, move this device farther away or
change its orientation.
352a
If this device is operated near a television or radio, color
distortion may be seen in the television screen or noise may
be heard from the radio. If this occurs, move this device
farther away.
352b
Keep your cell phone powered off or at a sufficient distance
from this device. If a cell phone is nearby, noise may be
heard when a call is received or initiated, or during
conversation.
354b
Do not leave this device in direct sunlight, near devices that
produce heat, or in a closed-up automobile. Do not allow
illumination devices operated in close proximity (such as a
piano light) or powerful spotlights to shine on the same
location on this device for an extended time. This can cause
deformation or color change.
355b
If you move this device between locations of radically different
temperature or humidity, water droplets (condensation) may
form inside the device. Using the device in this condition will
cause malfunctions, so please allow several hours for the
condensation to disappear before you use the device.
356
Do not allow items made of rubber or vinyl to remain on
top of this device for an extended time. This can cause
deformation or color change.
358
Do not leave objects on top of the keyboard. This can
cause malfunctions such as failure to sound.
359
Do not affix adhesive labels to this device. The exterior
finish may be damaged when you remove the labels.
Care
401b
For everyday care, wipe with a soft dry cloth, or remove
stubborn dirt using a tightly wrung-out cloth. If this device
contains wooden components, wipe the entire area
following the direction of the grain. The finish may be
damaged if you continue strongly rubbing a single location.
Addition
If water droplets should adhere to this device, immediately
wipe them off using a soft dry cloth.
402
Do not use solvents such as benzene, thinner, or alcohol,
since these can cause deformation or color change.
403
The pedals of this device are made of brass.
Brass has a natural tendency to oxidize and become tarnished.
If this occurs, use a commercially available metal polish.
Servicing
452
If you return this device for servicing, the contents of
memory may be lost. Please store important contents on
USB memory, or make a note of the contents. We take
utmost care to preserve the contents of memory when
performing service, but there may be cases when the stored
content cannot be recovered because the memory section
has malfunctioned. Please be aware that we cannot accept
responsibility for the recovery of lost memory content or for
any consequences of such loss.
Other Cautions
551
Stored content may be lost due to a malfunction of the
device or because of inadvertent operation. You should
back up important content on USB memory as a safeguard
against such loss.
552
We cannot accept responsibility for the recovery of any
content lost from internal memory or USB memory, or for
the consequences of such loss.
553
Do not apply excessive force to the buttons, knobs, or
input/output jacks, since this may cause malfunctions.
554
Never strike or apply strong pressure to the display.
556
When connecting or disconnecting cables, grasp the plug
(not the cable) to prevent short circuits or broken
connections.
557
This device may produce a certain amount of heat, but this
is not a malfunction.
558a
Please enjoy your music in ways that do not inconvenience
other people nearby, and pay particular attention to the
volume at nighttime. Using headphones will allow you to
enjoy music without having to be concerned about others.
559b
When transporting or shipping this device, package it in an
appropriate amount of cushioning material. Scratches,
damage, or malfunctions may occur if you transport it
without appropriate packaging.
560
If using the music rest, do not apply excessive force to it.
