• Before moving the instrument, remove all connected cables, to prevent damage to the cables or injury to
anyone who might trip over them.
•

are not using the product for a long time, make sure to unplug the power cord from the wall AC outlet.
• 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.
