n NOTE ON USING CIRCUIT DIAGRAMS
1. SAFETY
The components identified by the symbol and shading are critical for safety. For continued safety replace safety critical components only with manufactures recommended parts.

5.NOTE FOR REPAIRING SERVICE
This models power circuit is partly different in the GND. The difference of the GND is shown by the LIVE : () side GND and the ISOLATED(NEUTRAL) : () side GND. Therefore, care must be taken for the following points. (1)Do not touch the LIVE side GND or the LIVE side GND and the ISOLATED(NEUTRAL) side GND simultaneously. If the above caution is not respected, an electric shock may be caused. Therefore, make sure that the power cord is surely removed from the receptacle when, for example, the chassis is pulled out. (2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL) side GND or never measure with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND and ISOLATED(NEUTRAL) side GND at the same time. If the above precaution is not respected , a fuse or any parts will be broken. Since the circuit diagram is a standard one, the circuit and circuit constants may be subject to change for improvement without any notice.
