2. Disassembly Instructions
[ Caution ]
• Before disassembly of the projector, turn off the power switch and disconnect the power plug from the wall outlet.
[Note]
• 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 electro-statics discharge and surges which affects the set reliability.
Please take care for electro-static discharges by using grounded wrist straps to release the electricity from the body.
• When tore off sticky tapes, use a new thing without reusing it on the occasion of assembling.
• Make sure that all the connectors are connected completely after assembling.
