5  Using the tip of a straight pin or paper clip, 
change the position of the switch, for example, if 
the switch is in the down position, push it to the 
up position. The Touch Screen will then sense the 
change on the next power up, and will initiate the 
restore process. 
6  When you are finished with the restore, reattach 
the Touch Screen into the power box in the wall—
top first—and then snap the bottom of the Touch 
Screen back into place. 
7  The Touch Screen will reboot and the factory 
default firmware image will be installed. All 
settings will reset to the factory default settings. 
See “LED Indicator” for information about how 
the LED behaves during a factory restore. 
8  After a restore, the Touch Screen will need to be 
updated to the same image version of the project 
(e.g., OS 2.2.2 or later).
