Please Note. 
 
  The opening of the LCD panel assembly needs to be done in a clean/dust free 
enviroment. 
  The replacement sheets have a front and rear. It is important that all sheets are 
assembled with their cut-off, shown in Figure 3 to the R.H. lower corner of the panel 
assembly as this will ensure they are assembled correctly. 
  The replacement lens sheets have no protection film and are assembled as supplied. 
  The panel layers should be handeled with great care and only held at their edges and 
only when being assembled. 
allow dirt/dust containation. 
  Before final assembly please complete a lighting test to ensure nothing is trapped 
within or has containated the sheets.
