Under extreme circumstances, it may be necessary to reset the system. Reset the system if the following situation occurs: 
 • Slow screen refresh rate or sluggish operation, resulting in an inoperable unit. 
 • The system will not turn Off with the On/Off button. 
 • No response to any selection made on the screen. 

 The reset button can be found on the rear of the unit. Insert the tip of a stylus pen or small blunt object into the reset hole to press the button. The system will be immediately reset.
