■ Optical Adjustments
Before taking optical adjustments below, remove the Cabinet Top following to the "Mechanical Disassemblies".
Adjustments require a 2.0mm hex wrench and a slot screwdriver. When you adjust Integrator lens, Relay lens or
Mirror adjustment, you need to disconnect FPC cables of LCD panels on the main board.
Note: Do not disconnect connectors on the main board, because the projector cannot turn on due to operate the
power failure protection.
When the cabinet top or lamp cover is removed, the lamp cover switch is turned off. When turning on the pro-
jector for servicing or adjusting, it is required to keep turning on the lamp cover switch.
