Note 1: In this set, only a part of parts that relate to the switch are supplied. Therefore, the schematic diagram excerpts and has described only a part. Replace a part according to “METHOD OF JUDGING RIGHT AND WRONG OF PARTS RELATED TO SWITCH” (page 7) in servicing notes. Exchange the entire mounted board when parts that do not correspond to it are defective.
Note 2: When the MAIN board is replaced, there are some notes. Refer to “NOTE THE MAIN BOARD REPLACING” (page 4) in servicing notes for notes.
