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:
Power supply/AC adaptor
• 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.
Location
• 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.
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 [ ] (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 and Maintenance
• 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 the application on your iPhone/iPad, we recommend that you set "Airplane Mode" to "ON"
on your iPhone/iPad 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 keyboard.
• When cleaning the instrument, use a soft, dry/dry or slightly damp cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated
wiping cloths.

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.
• 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.
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. 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.
