Connections
Before connecting the instrument to other electronic compo-
nents, turn off the power for all components. Before turning the
power on or off for all components, set all volume levels to mini-
mum. 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 or slightly damp
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.
Handling caution
Take care that the key cover does not pinch your fingers, and do
not insert a finger or hand in any gaps on the key cover or
instrument.
Never insert or drop paper, metallic, or other objects into the
gaps on the key cover, 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 instru-
ment, 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.
Using the bench (If included)
Do not place the bench in an unstable position where it might
accidentally fall over.
Do not play carelessly with or stand on the bench. Using it as a
tool or step-ladder or for any other purpose might result in acci-
dent or injury.
Only one person should sit on the bench at a time, in order to
prevent the possibility of accident or injury.
If the bench screws become loose due to extensive long-term
use, tighten them periodically using the included tool.
