Important Notes

 

 

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.

 

306b

 

• Batteries are included with this device. These batteries are 

for the purpose of testing the operation of this device, and 
their lifespan may be shorter than normal.

 

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.

 

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.

 

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.

 

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.

 

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

 

• Do not apply strong pressure to the display or strike it.

 

555
