PSR-S900/S700 Owner’s Manual 23
Introduction
Handling the USB Storage Device (USB Flash Memory/Floppy Disk, etc)
This instrument features a built-in [USB TO DEVICE] termi-
nal. By connecting the instrument to a USB storage device
with a standard USB cable, you can save data you’ve cre-
ated to the connected device, as well as read data from the
connected device. Be sure to handle USB storage device
with care. Follow the important precautions below.
nFor more information about the handling of USB stor-
age device, refer to the owner’s manual of the USB stor-
age device.

Compatible USB storage devices

• Up to two USB storage devices, such as a floppy disk
drive, hard disk drive, CD-ROM drive, flash memory
reader/writer, etc., 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 with
musical instruments simultaneously even when a USB
hub is used is a maximum of two.) This instrument can
recognize up to four drives in one USB storage device.
Other USB devices such as a computer keyboard or
mouse cannot be used.
•The instrument does not necessarily support all commer-
cially available USB storage devices. Yamaha cannot
guarantee operation of USB storage devices that you
purchase. Before purchasing USB storage devices,
please consult your Yamaha dealer, or an authorized
Yamaha distributor (see list at end of the Owner’s Man-
ual) for advice, or visit the following web page:

nAlthough CD-R/RW drives can be used to read data to
the instrument, they cannot be used for saving data.

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.

Using USB Storage Devices

• When connecting a USB storage device to the [USB TO
DEVICE], make sure that the connector on the device is
appropriate and that it is connected in the proper direc-
tion. 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).
• If you are connecting two or three devices at the same
time (such as two USB storage devices and a LAN adap-
tor), 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.
CAUTION
The format operation overwrites any previously existing
data. Make sure that the media you are formatting does
not contain important data. Proceed with caution, espe-
cially when connecting multiple USB storage medias.
CAUTION
Avoid frequently turning the power on/off to the USB
storage device, or connecting/disconnecting the cable
too often. Doing so may result in the operation of the
instrument “freezing” or hanging up. While the instru-
ment is accessing data (such as in the Save, Copy and
Delete operations), do NOT unplug the USB cable, 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.
