LED/LCD Screen Installation Note
When installing the LED/LCD display unit of the EOI, ensure that the left side of the display is inserted
first with the top and bottom catches (see Phillips screws at underside of display) securely in place. This
ensures the proper alignment and electrical connection of the CNX connector of the LED/LCD display
unit board. Gently hold the display in place while securing the Phillips mounting screw.
If improperly seated, the periphery of the LED/LCD display unit will not be flush with the EOI surface,
and the unit will not function properly.
