3.1.6 Precautions
These precautions are for the individual assembly and disassembly procedures. Read
them carefully before starting an assembly or disassembly procedure. A set of general
precautions is given below.
As you disassemble the main unit, dust that has collected on the internal fans and air filters
is likely to migrate and contaminate light valves R, G, and B (the heart of the display
mechanism), deteriorating the display quality. To prevent this from occurring, check for
dust inside of the main unit and, if necessary, clean it with a vacuum cleaner before
reassembling. Light valves R, G, and B and circuit board assemblies are highly sensitive to
static electricity. When you remove an optical engine or circuit board, place it in an anti-
static bag immediately.
When you perform the assembly or disassembly operations listed below, check the unit
and its surfaces for any dirt before reinstalling them. If the unit is dirty, clean it.
1. Removing the optical engine.
2. Removing the lamp inner housing.
3. Removing the air filter frame.
The speaker unit incorporates a permanent magnet. Keep it away from electromagnetic
media such as floppy disks and magnetic cards.
Handle the optical engine (projector lens and light guide unit) with care. They are highly
susceptible to vibration and shock.
Do not try to disassemble any part (e.g., power supply unit) that is not covered in this
manual.
