(1) Precautions
Before starting disassembly, press the Power key on the operation panel to off. Make sure that the Power
lamp is off before turning off the main power switch. Unplug the power cable from the wall outlet.
When handling PWBs (printed wiring boards), do not touch parts with bare hands.
The PWBs are susceptible to static charge.
Do not touch any PWB containing ICs with bare hands or any object prone to static charge.
When removing the hook of the connector, be sure to release the hook.
Take care not to get the cables caught.
To reassemble the parts, use the original screws. If the types and the sizes of screws are not known, refer to
the PARTS LIST.
