 CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage 
to the instrument or other property. These precautions include, but are not limited to, the following:

• Do not connect the instrument to an electrical outlet using a multiple-connector. Doing so 

can result in lower sound quality, or possibly cause overheating in the outlet.

• When removing the electric plug from the instrument or an outlet, always hold 

the plug itself and not the cord. Pulling by the cord can damage it.

• Remove the electric plug from the outlet when the instrument is not to be used for 

extended periods of time, or during electrical storms.

• Do not place the instrument in an unstable position where it might accidentally 

fall over.

• Before moving the instrument, remove all connected cables, to prevent damage 

to the cables or injury to anyone who might trip over them.

• When setting up the product, make sure that the AC outlet you are using is easily 

accessible. If some trouble or malfunction occurs, immediately turn off the power 
switch and disconnect the plug from the outlet. Even when the power switch is 
turned off, electricity is still flowing to the product at the minimum level. When 
you are not using the product for a long time, make sure to unplug the power 
cord from the wall AC outlet.

• Before connecting the instrument to other electronic components, turn off the 

power for all components. Before turning the power on or off for all components, 
set all volume levels to minimum.

• Be sure to set the volumes of all components at their minimum levels and 

gradually raise the volume controls while playing the instrument to set the 
desired listening level.

• Do not insert a finger or hand in any gaps on the instrument. 

• Never insert or drop paper, metallic, or other objects into the gaps on the panel. 

This could cause physical injury to you or others, damage to the instrument or 
other property, or operational failure.

• Do not rest your weight on, or place heavy objects on the instrument, and do not 

use excessive force on the buttons, switches or connectors.

• Do not use the instrument/device or headphones for a long period of time at a high or 

uncomfortable volume level, since this can cause permanent hearing loss. If you 
experience any hearing loss or ringing in the ears, consult a physician.

Always turn the power off when the instrument is not in use. 

Even when the [

] (Standby/On) switch is in standby status (display is off), electricity is still flowing to the instrument at the minimum level. 

When you are not using the instrument for a long time, make sure you unplug the power cord from the wall AC outlet.

Make sure to discard used batteries according to local regulations.

NOTICE

To avoid the possibility of malfunction/ damage to the product, damage to data, or 
damage to other property, follow the notices below.



Handling

• Do not use the instrument in the vicinity of a TV, radio, stereo equipment, mobile 

phone, or other electric devices. Otherwise, the instrument, TV, or radio may 
generate noise. When you use the instrument along with an application on your 
iPad, iPhone or iPod touch, we recommend that you set “Airplane Mode” to “ON” 
on that device in order to avoid noise caused by communication. 

• Do not expose the instrument to excessive dust or vibrations, or extreme cold or 

heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent 
the possibility of panel disfiguration, damage to the internal components or 
unstable operation. (Verified operating temperature range: 5° – 40°C, or 41° – 
104°F.)

• Do not place vinyl, plastic or rubber objects on the instrument, since this might 

discolor the panel or pads.



Maintenance

• When cleaning the instrument, use a soft cloth. Do not use paint thinners, 

solvents, alcohol, cleaning fluids, or chemical-impregnated wiping cloths.



Saving data

• The saved data may be lost due to some failure, an operation mistake, etc. Save 

your important data onto an external device such as a computer (page 38).
