Possible solution
Confirm that the USB flash drive you are using works properly with a computer.
Use a tested USB flash drive. Refer to Yamaha Pro Audio global website (http://
www.yamahaproaudio.com/) for tested USB flash drive. Should this also fail, con-
tact your Yamaha dealer.
Make sure the USB flash drive has enough free space.
Try again. The [USB] indicator flashes when the USB flash drive is being
accessed. Do not unplug the USB flash drive during this time.
