Owner’s Manual

• 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. Also, 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.

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

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

• 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. If this happens, turn off the power 
immediately and unplug the power cord from the AC outlet. Then 
have the instrument inspected by qualified Yamaha service 
personnel. 

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

this might discolor the panel or keyboard.

• 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.

Saving and backing up the created Control 
Template

• The Control Template created by using a computer or via the panel 

operation of the KX will be stored on internal memory of the KX. 
Stored data may be lost due to malfunction or incorrect operation. 
Save important data to a computer by using the special KX Editor 
software (page 6). 

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

Even when the power switch is in the “STANDBY” position, 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 AC power adaptor from the wall AC outlet.
