USB Flash Drive and USB Flash Drive 
Port Handling Precautions
IMPORTANT!
• Be sure to observe the precautions provided in the 
documentation that comes with the USB flash drive.
• Avoid using a USB flash drive under the following 
conditions. Such conditions can corrupt data stored 
on the USB flash drive.
• Areas subjected to high temperature, high 
humidity, or corrosive gas
• Areas subjected to strong electrostatic charge and 
digital noise
• Never remove the USB flash drive while data is 
being written to or loaded from it. Doing so can 
corrupt the data on the USB flash drive and damage 
the USB flash drive port.
• Never insert anything besides a USB flash drive into 
the USB flash drive port. Doing so creates the risk of 
malfunction.
• A USB flash drive can become warm after very long 
use. This is normal and does not indicate 
malfunction.
• Static electricity conducted to the USB flash drive 
port from your hand or from a USB flash drive can 
cause malfunction of the digital piano. If this 
happens, turn the digital piano off and then back on 
again.
IMPORTANT!
• Never plug any other device besides a USB flash 
drive into the USB flash drive port.
• When you plug in a USB flash drive, the Digital 
Piano initially needs to “mount” the USB flash drive 
and prepare for data exchange. Note that Digital 
Piano operations are momentarily disabled while a 
USB flash drive mounting sequence is being 
performed. The Digital Piano’s L/R lamps flash while 
the mounting process is in progress. It may take up 
to 10 or 20 seconds or even longer for a USB flash 
drive to be mounted. Do not attempt to perform any 
operation on the Digital Piano while a mounting 
sequence is in progress (while L/R lamps are 
flashing). A USB flash drive needs to be mounted 
each time it is connected to the Digital Piano.
■ To insert a USB flash drive
1.
As shown in the illustration below, insert the 
USB flash drive into the digital piano’s USB 
flash drive port.
• Carefully push the USB flash drive in as far as it will 
go. Do not use undue force when inserting the USB 
flash drive.
■ To remove a USB flash drive
1.
Check to confirm that there is no data 
exchange operation being performed, and 
then pull the USB flash drive straight out.
