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:
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.
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.
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.
Never insert or drop paper, metallic, or other objects into the gaps on the panel. 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.
Always turn the power off when the instrument is not in use.
Even when the [ ] button 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 the instrument according to local regulations.

Handling
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.

tablet, we recommend that you set Bluetooth to on after setting “Airplane Mode” to on on that device in
order to avoid noise caused by communication.
Do not use the instrument within 3 m (10 ft.) of a Wi-Fi router.
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. In the place where temperature is very high or low, the
built-in battery may be recharged earlier than usual or fail to be recharged.
Do not place vinyl, plastic or rubber objects on the instrument, since this might discolor the panel or keyboard.
Magnetism occurs in the bottom of the instrument as a speaker is built into the instrument. Do not put
anything affected by magnetism like a clock, cash card, etc., nearby the instrument.
