- Service Precaution

• You should conform to the regulations governing the product (safety, radio and noise, and other regulations),
and should keep the safety during servicing by following the safety instructions described in this manual.

• Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by
electrostatic induction.

• The area where the temperature gets high as a completely assembled product is the heat sink. As a unit, on

C

the other hand, sub-heat sink and the periphery of the sub-heat sink are the areas where the temperature
gets high.

• There is a danger for electrical shock in the periphery of an area where “High Voltage Attention” is indicated
on the printed circuit board due to a high voltage being generated during operation. Therefore, be careful
when working around such areas.

In addition, be sure that there are no pinched wires, etc.

7 Make sure screws and soldering scraps do not remain inside the product.

Please check that neither solder debris nor screws remain inside the product.

8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.

Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.

9 There should be no spark traces or similar marks on the power plug.

When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
