1. Before servicing, unplug the power cord to prevent an electric shock.
2. When replacing parts, use only the manufacturer's recommended components for safety.
3. Check the condition of the power cord. Replace if wear or damage is evident.
4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure to perform the following insulation resistance test to prevent

the customer from being exposed to shock hazards.

1. Cover the plastic parts boxes with aluminum foil.
2. Ground the soldering irons.
3. Use a conductive mat on the worktable.
4. Do not touch IC or LSI pins with bare fingers.

1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with ohmmeter between the jumpered AC plug and each exposed metal cabinet part, such as

screw threads, control shafts, handle brackets, etc.
Note:

Some exposed parts may be isolated from the chassis by design. These will read infinity.

4. If the measurement is outside the specified limits, there is a possibility of shock hazard. The equipment should be repaired

and rechecked before it is returned to the customer.

1. HDD must be handled standing on rubber insulating.
2. Operator must wear grounding strap at when handling HDD.
3. Do not touch circuit.
4. Metal frame and HDD must be assembled with shock-proofed torque controlled screwdriver. (Loosing torque 0.4~0.6n. m)
5. Do not press HDD when securing screw. (Hold metal frame)
6. Take care when handling HDD. HDD is sensitive to shock.

The power socket wall outlet should be located near this equipment and be easily accessible.
