• 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.
• 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 power switch is in the “STANDBY” position, 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.
