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.
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.)
The instrument does not necessarily support all commer-
cially available USB devices. Yamaha cannot guarantee
operation of USB devices that you purchase. Before pur-
chasing a USB device for use with this instrument, please
visit the following web page:

Other USB devices such as a computer keyboard or
mouse cannot be used.

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.
•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.

Using USB Storage Devices

By connecting the instrument to a USB storage device, you can save data you’ve created to the
connected device, as well as read data from the connected device.
Although CD-R/RW drives can be used to read data to the instrument, they cannot be used for saving data.

Number of USB storage devices that can

be used

Only one USB storage device can be connected to the
USB [TO DEVICE] terminal.

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 35).
CAUTION
The format operation overwrites any previously existing data.
Make sure that the media 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 stor-
age 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 and Delete operations).
CAUTION
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 dur-
ing Save, Delete, Load 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.
