2. Disassembly Instructions
[Caution]
* Before disassembly the projector, turn off the power switch and disconnect the power plug from the wall outlet.
* During the disassemble work, please wear gloves to protect your hands from metal parts and shield plate.
* Electrical parts such as PCBs, may get damaged by electrostatics discharge and/or surges which affects the set reliability.
Please take care for electrostatic discharges by using grounded wrist straps to release the electricity from the body.
* When tore off sticky tapes, please use a new thing without reusing it on the occasion of assembling.
Please use the special table pad specified below or substitution when disassembling and assembling.
Place the projector onto the special table pad to disassemble and assemble.
When mounting the lighting case or duct block onto the cabinet bottom case, the cabinet bottom case might be bent due to
applying the over power force.
As the result, the tiny gap will be come up between the air duct and cabinet bottom case. This gap have an effect on the
temperature control inside projector.
