Important Notes
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.
302
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a cause
for concern.
307
• Before you make connections, you must switch off the power
on all devices to prevent malfunction and/or speaker damage.
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.
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.
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.
358
• Do not leave objects on top of the keyboard. This can
cause malfunctions such as failure to sound.
360
• Depending on the material and temperature of the surface
on which you place the unit, its rubber feet may discolor or
mar the surface.
You can place a piece of felt or cloth under the rubber feet
to prevent this from happening. If you do so, please make
sure that the unit will not slip or move accidentally.
Care
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.
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.
Servicing
452
• If you return this device for servicing, the contents of
memory may be lost. Please store important contents on a
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 a 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.
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.
559a
• 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.
561
• Use only the specified expression pedal (EV-5/7; available
separately). Connecting a pedal made by a different
manufacturer may cause this device to malfunction.
