Precautions when Using the 5V DC / USB TO

When connecting the computer to the 5V DC / USB TO HOST terminal (page 6 in the Owner's Manual), make sure to observe the fol-
lowing points to avoid freezing the computer and corrupting or losing the data.
• Use an A-micro B type USB cable of less than 3 meters. USB 3.0 cables cannot be used.
• Execute the following before turning the power to the instrument on/off or plugging/unplugging the USB cable to/from the 5V DC /
USB TO HOST terminal.
• Quit any open application software on the computer.
• Make sure that data is not being transmitted from the instrument. (Data is transmitted only by playing notes on the keyboard or
playing back a song.)
• While the computer is connected to the instrument, you should wait for six seconds or more between these operations: (1) when turn-
ing the power of the instrument off then on again, or (2) when alternately connecting/disconnecting the USB cable.
If the computer or the instrument freezes, restart the application software or the computer OS, or turn the power to the instrument off
then on again.
