1.2  NOTES ON DISASSEMBLY / ASSEMBLY

1.3  NOTES ON REPLACING PARTS

1.4  NOTES ON ADJUSTMENT

1.5  OTHERS

 

 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.

 

 Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during power-on 

mode may damage the ICs inside the unit.

 

 Please be sure to conduct line process to original status if you make assembling after repair.

 

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

induction.

 

 Please be careful of not to apply static charge onto integrated circuits, etc, when you conduct repair work.

 

 Especially, please use soldering iron with its tip grounded.

 

 Also, please use a pair of tweezers with static charge protection capability if there is the possibility of contacting to 

device terminals, and avoid the use of metal-made tweezers.

 

 There is not information to be shown in this chapter.

 

For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. 

Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for
repairs accompanied by reworking of soldering.
