Connections
• 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.
Maintenance
• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
Even when the instrument turns the power 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 AC power adaptor from the wall AC outlet.
Handling caution
• 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 operate the instrument 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 data
Saving and backing up your data
• Data in the instrument' s internal memory can be lost due to operational errors or
malfunction. Be sure to save any important data to external media via a
computer connection. (page 50)
