Precautions when using the USB
[TO DEVICE] terminal
This instrument features a built-in USB [TO
DEVICE] terminal. When connecting a USB device
to the USB [TO DEVICE] terminal, be sure to
handle the USB device with care. Follow the
important precautions below.
NOTE
For more information about the handling of USB devices,
refer to the owner’s manual of the USB device.
 Compatible USB devices
• USB flash drive
Other USB devices such as a USB hub, computer
keyboard or mouse cannot be used.
The instrument does not necessarily support all
commercially available USB devices. Yamaha cannot
guarantee operation of USB devices that you purchase.
Before purchasing a USB device for use with this
instrument, please visit the following web page:
https://download.yamaha.com/
Although USB devices 2.0 to 3.0 can be used on this
instrument, the amount of time for saving to or loading
from the USB device may differ depending on the type
of data or the status of the instrument.
NOTICE
The rating of the USB [TO DEVICE] terminal is a
maximum of 5V/500mA. Do not connect USB devices
having a rating above this, since this can cause damage
to the instrument itself.
 Connecting a USB device
When connecting a USB device to the USB [TO
DEVICE] terminal, make sure that the connector on
the device is appropriate and that it is connected in the
proper direction.
NOTICE
• Avoid connecting or disconnecting the USB device
during playback/recording and file management
operations (such as Save, Copy, Delete and Format),
or when accessing the USB device. Failure to
observe this may result in “freezing” of the operation
of the instrument or corruption of the USB device and
the data.
• When connecting then disconnecting the USB device
(and vice versa), make sure to wait a few seconds
between the two operations.
• Do not use an extension cable when connecting a
USB device.
 Using USB flash drives
By connecting the instrument to a USB flash drive, you
can save data you’ve created to the connected device, as
well as read data from the connected device.
• Number of USB flash drives that can be used
Only one USB flash drive can be connected to the
[USB TO DEVICE] terminal.
 Formatting a USB flash drive
You should format the USB flash drive only with this
instrument (page 41). A USB flash drive formatted on
another device may not operate properly.
NOTICE
The format operation overwrites any previously existing
data. Make sure that the drive you are formatting does
not contain important data.
 To protect your data (write-protect)
To prevent important data from being inadvertently
erased, apply the write-protect provided with each USB
flash drive. If you are saving data to the USB flash drive,
make sure to disable write-protect.
 Turning off the instrument
When turning off the instrument, make sure that the
instrument is NOT accessing the USB flash drive by file
management (such as during Save, Copy, Delete and
Format operations). Failure to do so may corrupt the
USB flash drive and the data.
Precautions when using the USB [TO
HOST] terminal
When connecting the computer to the USB [TO
HOST] terminal, make sure to observe the following
points to avoid freezing the computer and corrupting
or losing the data.
NOTICE
• Use an AB type USB cable. 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 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.)
• While the computer is connected to the instrument,
you should wait for six seconds or more between
these operations: (1) when turning 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.
