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 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 storage devices (flash memory, floppy disk drive, hard
disk drive, etc.)
• USB hub
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:

NOTE
Other USB devices such as a computer keyboard or mouse
cannot be used.
Using USB Storage Devices
By connecting the instrument to a USB storage device (external media), you can save data you've created to the
connected device, as well as read data from the connected device.
■ The number of USB storage device to be
used
Up to two USB storage devices can be connected to the USB TO
DEVICE terminal. (If necessary, use a USB hub. The number of
USB storage devices that can be used simultaneously with
musical instruments even when a USB hub is used is a maximum
of two.)
■ Formatting USB storage media
When a USB storage device is connected or media is inserted, a
message may appear prompting you to format the device/ media.
If so, execute the Format operation (page 11).
The format operation overwrites any previously existing
data. Make sure that the media you are formatting does not
contain important data. Proceed with caution, especially
when connecting multiple USB storage media.

■ Connecting 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.
• When connecting a USB cable, Use it less than 3 meters.
• If you intend to connect two or three devices at the same time
to a terminal, you should use a USB hub device. The USB hub
must be self-powered (with its own power source) and the
power must be on. Only one USB hub can be used. If an error
message appears while using the USB hub, disconnect the hub
from the instrument, then turn on the power of the instrument
and re-connect the USB hub.
• Though the instrument supports the USB 1.1 standard, you
can connect and use a USB 2.0 storage device with the
instrument. However, note that the transfer speed is that of
USB 1.1.
■ To protect your data (write-protect)
To prevent important data from being inadvertently erased, apply
the write-protect provided with each storage device or media. If
you are saving data to the USB storage device, make sure to
disable write-protect.
■ Connecting/removing USB storage device
Before removing the media from the device, make sure that the
instrument is not accessing data (such as in the Save, Copy and
Delete operations).
Avoid frequently turning the power on/off to the USB
storage device, or connecting/disconnecting the device too
often. Doing so may result in the operation of the
instrument "freezing" or hanging up. While the instrument
is accessing data (such as during Save, Copy, Delete, and
Format operations) or is mounting the USB storage device
(shortly after the connection), do NOT unplug the USB
connector, do NOT remove the media from the device, and
do NOT turn the power off to either device. Doing so may
corrupt the data on either or both devices.
