DGX-660  Owner’s Manual

• 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.

• Read carefully the attached documentation explaining the assembly process. 

Failure to assemble the instrument in the proper sequence might result in 
damage to the instrument or even injury. 

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

fall over.

• When transporting or moving the instrument, always use two or more people. 

Attempting to lift the instrument by yourself may damage your back, result in 
other injury, or cause damage to the instrument itself.

• 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.

• Use only the stand specified for the instrument. When attaching it, use the 

provided screws only. Failure to do so could cause damage to the internal 
components or result in the instrument falling over.

• 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 or 

keyboard. 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.

Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed.
