■ Optical Adjustment
Before taking optical adjustments below, remove the Cabinet Top and Main Board following to the “Mechanical
Disassemblies”
Adjustments require a 2.0mm hex wrench and a slot screwdriver. When you adjust Integrator lens or Relay lens
adjustment, you need to disconnect some connectors and FPC cables of LCD panels on the main board.
Note:
Do not disconnect connectors on the main board, because the projector can not turn on or operate properly for
adjustment.
