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
• Do not connect the instrument to an electrical outlet using a
multipleconnector. 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 USB cable. Pulling
by the USB cable 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.
• Use the specified USB power adaptor (page 10) only. Using the
wrong adaptor canresult in damage to the instrument
oroverheating.
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 using an electric plug, make sure that the AC outlet you
are using is easily accessible in plain view. 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 disconnect the plug from the wall AC outlet.
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.
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 (power lamp 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.
Handling
• 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 keys. 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 if the mouthpiece, reed or ligature is
damaged.
• Keep small parts out of the reach of infants. Your children may
accidentally swallow them.
• 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.
• When using a strap, make sure the strap is securely attached to
the instrument.
• Do not lift the instrument by the strap. It can cause serious injury
or damage to the instrument.
• Do not treat the instrument in a rough manner such as swinging
it about, etc. The strap on the instrument may detach causing
unexpected accidents such as the instrument dropping, etc., or
injuring persons close by.
