If the screen does not respond correctly when you touch a key (the machine does not perform the operation or performs a different operation), follow the steps below to make the proper adjustments.
 

1. Holding your finger on the LCD screen, turn the main power to off and back to on.
   
   >> The touch panel adjustment screen is displayed.
    
2. Using the included touch pen, lightly touch the center of each +, in order from 1 to 5.
   
   >> After completing the touch panel adjustment, the message “SUCCESS” appears on the screen.
    
3. Turn the main power to off, then turn it back to on.

   If you finish the screen adjustment and the screen still does not respond correctly, or if you cannot do the adjustment, contact the retailer who sold you this machine or the nearest authorized service center.
