Before turning the power off, be sure to turn down the volume of all devices to
avoid speaker damage or malfunctions.
Before disconnecting the USB cable which connects your computer and the UM-4,
halt any operations which record or playback MIDI data. This will prevent the
sound module etc. from malfunctioning. It is not necessary to turn off the power of
