* Most common USB storage devices are complied with the specification above and can
be used for updating. However, the operation in this equipment is not always
guaranteed since the most of these devices are developed based on the use in PC
environ ment (Windows or Macintosh). Therefore, confirm thoroughly that the device is
opera tional in this equipment when purchasing the device.
• The USB storage device complied with USB1.1 and USB2.0 can be used for updating. How-
ever, the update is performed in the speed of USB1.1 when the device complied with USB2.0
is used.
• Do not update the firmware by any storage device other than a flash memory (such as a USB
connection type memory card reader, CD/DVD drive or hard disk) since it is never guaran-
teed.
