Removing Audio Components
Caution Take care not to mar or introduce smudges or dirt to the surface of the projector screen.
Step 1 Power off the system by completing turning off the following units:
• The two left PDUs on the left accessory cabinet
• The single right PDU on the right accessory cabinet
• The auxiliary control unit on the center display structure
Caution Make sure all system power is turned off before beginning this disassembly.
Step 2 Remove the Projector screen by performing one of the following actions:
• If your projector screen is slightly recessed and uses black side trims, complete the following steps:
a. Remove the side trims from the edges of the display.
Be careful not to mar the screen when you perform this step.
b. Use an open-ended wrench to loosen the feet on the bottom of the screen, and lower the screen.
c. After you have created a gap of approximately 1/2 inch (1 centimeter) between the screen and
the display shelf, detach the holes on the top screen from the locating pins on the underside of
the display shelves and remove the screen.
• If your projector screen does not have side trims and is flush with the display cabinet, grasp the outer
edges of the screen and pull it up and away from the Projector clips that hold the screen to the
Display shelves.
Step 3 Disconnect the Speaker cables from the Speaker terminals.
