Battery
• Follow the precautions below. Failure to do so might result in
explosion, fire, overheating or battery fluid leakage.
- Do not tamper with or disassemble batteries.
- Do not dispose of batteries in fire.
- Do not attempt to recharge batteries that are not designed to
be charged.
- Keep the batteries separate from metallic objects such as
necklaces, hairpins, coins, and keys.
- Use the specified battery type (page 40) only.
- Use new batteries, all of which are the same type, same model,
and made by the same manufacturer.
- Always make sure all batteries are inserted in conformity with
the +/- polarity markings.
- When the batteries run out, or if the instrument is not to be
used for a long time, remove the batteries from the instrument.
- When using Ni-MH batteries, follow the instructions that came
with the batteries. Use only the specified charger device when
charging.
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.
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.
• Keep batteries away from small children who might accidentally
swallow them.
• If the batteries do leak, avoid contact with the leaked fluid. If the
battery fluid should come in contact with your eyes, mouth, or
skin, wash immediately with water and consult a doctor. Battery
fluid is corrosive and may possibly cause loss of sight or
chemical burns.
If you notice any abnormality
• When one of the following problems occur, immediately turn off
the power switch and disconnect the electric plug from the
outlet. (If you are using batteries, remove all batteries from the
instrument.) Then have the device inspected by Yamaha service
personnel.
- The power cord or plug becomes frayed or damaged.
- It emits unusual smells or smoke.
- Some object has been dropped into the instrument.
- There is a sudden loss of sound during use of the instrument.
- If any cracks or breakages exist on the instrument.
• 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
• 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.
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 [P] (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.
