3.7. Parts location and direction in the lighting case
When mounting or assembling the parts in the lighting case, the parts must be mounted in the speci-
fied location and direction as shown in the figure below.
Note: The parts indicated with (*) are mounted by adhesive, therefore, they cannot be replaced
individually.

4. Cleaning of Optical Parts
4.1. Note on handling of inorganic polarizer
This projector provides high durable inorganic polarizer which has a rib shaped evaporated aluminum on the glass surface.
This surface is very delicate. If touching or wiping the surface, the polarizing function will be lost due to damage of the alu-
minium rib construction on the surface. Extreme care should be taken to handle the polarizer.
Inorganic polarizer handling
Never grasp the surface or edges of the polarizer with bare hand. If fat and oil on your hand adheres on the edges
of polarizer, the linear bolt may appear on the glass surface due to capillarity. Grasp the edges of the glass with
new gloves or with tweezers when handling it.
Inorganic polarizer cleaning
When removing the dust on the surface, use a commercial (inert gas) air spray or air blower to remove them.
Never use organic solvents.
Indication of light in-coming side and out-going side
The indication of "in-coming side" and "out-going side" of the polarizer or LCD panels is shown in the figure. It indicates the
light in-coming and out-going from the lamp.
Contact prohibition area of inorganic polarizer
The aluminum evaporated surface of inorganic polarizer is contact prohibition area. Prohibit touching it with bare hand, wip-
ing or contacting with the other parts.

SECTION 2 DISASSEMBLY PROCEDURES
The optical block cannot be disassembled.
The optical block is composed of very sensitive parts. There are some parts to bring on the performance down by touching or
wiping the surface of parts. Carry out the cleaning according to the cleaning guide table below.
The optical block has been adjusted preciously at the factory. Do not apply strong force to the LCD panel or frame on the
block.
