Precautions for assembly and disassembly
(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. And then unplug the power cable from the wall outlet. Turning off the main power
switch before pressing the Power key to off may cause damage to the equipped hard disk.
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 replacing battery on a PWB, dispose properly according to laws and regulations.
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.
