NOTICE
To avoid the possibility of malfunction/ damage to the
product, damage to data, or damage to other property,
follow the notices below.
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. When you use the instrument along
with an application on your smart device such as a
smartphone or tablet, we recommend that you set
“Airplane Mode” to “ON” on that device 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.
• Do not place vinyl, plastic or rubber objects on the
instrument, since this might discolor the panel or
keyboard.
Maintenance
• When cleaning the instrument, use a soft and dry (or
slightly damp) cloth. If the panel (front, side and
bottom, excepting the controllers and the keyboard) is
dirty, wipe the dirt away using a cloth moistened with a
neutral detergent solution and tightly wrung out.
Following this, wipe away the detergent solution using
a cloth soaked in water and tightly wrung out. Do not
use paint thinners, solvents, alcohol, or chemical-
impregnated wiping cloths.
• During extreme changes in temperature or humidity,
condensation may occur and water may collect on the
surface of the instrument. If water is left, the wooden
parts may absorb the water and be damaged. Make sure
to wipe any water off immediately with a soft cloth.
Saving data
• Edited Live Set Sounds (including settings of the
SETTINGS screens) and settings of MENU screens are
lost when you turn off the power to the instrument.
This also occurs when the power is turned off by the
Auto Power Off function (page 23). Save the data to the
instrument, or to USB flash drive/an external device
such as a computer (page 25). However, the data saved
to the instrument may be lost due to some failure, an
operation mistake, etc. Save your important data onto
USB flash drive/an external device such as a computer
(page 25). Before using a USB flash drive, make sure to
refer to page 26.
• To protect against data loss through USB flash drive
damage, we recommend that you save your important
data onto spare USB flash drive or an external device
such as a computer as backup data.
