Remove the 4 screws (Item 15) which hold the display bracket to the lower housing as indicated by the square 
(monitor) symbols molded into the lower housing (as shown). 

 

 

Care must be taken to ensure the display does not fall from the lower housing during disassembly. 

 

Lift the display assembly (Item 10) up to remove it from the lower housing. 

 

 

Ensure proper handling of removed display to prevent accidental damage. 

 

 
If the LCD assembly being removed has ferrite cores (item 63) on the white and black ELI380 Cable Assy as shown 
in the right-hand picture below, and the new assembly does not have the cores present, remove the ferrite cores from 
the old LCD assembly, by utilizing the snap connector latches on the core housings, and snapping them onto the new 
assembly as shown. If the cores were not present on the original assembly, they do not need to be added.
