Recessed Mounting Holes
IMPORTANT ! : Lower display must be installed before
installing upper display!
NOTE: If faceplate does not fit into recessed area of display,
proceed with the steps in this section.
1. Determine depth of recessed mounting holes relative to
back surface of display (against which faceplate will
contact).
2. Select proper length spacer and screw from table below:
NOTE: All spacers used should be the same length. If the
recess depths result in multiple spacer lengths, then
select the longer spacer.
CAUTION: Using screws of improper size may damage
your display! Proper screws will easily and completely thread
into display mounting holes.
3. Using Phillips screwdriver, carefully install two selected
screws (N or M) through selected spacers (Q or R) into the
upper mounting holes on the display. Thread screws
completely into display, then back out 3 complete turns.
(See Figure 12)
4. Pick up and align display so that screws (N or M) (installed
on the back of the display in the previous step) fit into the
mounting holes on the faceplate. Lower the display firmly
into place. (See Figure 12)

5. Slide two remaining selected spacers (Q or R) in between
faceplate and display, positioning them over the lower two
mounting holes. (See Figure 13)
6. Install two remaining selected screws (N or M) through
lower two mounting holes on faceplate, selected spacers (Q
or R) into the lower mounting holes on the display. (See
Figure 13)
