WARNING!!
This procedure is intended to be performed only by specially trained Melco service
technicians and personnel. Disassembly by untrained individuals will void any warranty protec-

and power switch energized with dangerous levels of voltage even when turned off and can
result in severe injury from electrical shock.

the power supply unit and the back of the switch.
