Caution
Components indicated by a mark   in this schematic diagram have 
the special significance in the safety. It is therefore, particularly 
recommended that the replacement of those parts must be made 
by exactly the same parts. Unauthorized substitutions may result 
in fire or accident.
This project is isolated from AC line by using the internal converter 
transformer. 
Please pay attention to the following notes in servicing. 
1.  Do not touch the part on the primary circuit or both the primary
and secondary circuits at the same time.
2.  Do not shorten the circuit between the primary and secondary
sides.
3.   The grounding lead must be connected to the ground of the
same circuit when measuring the voltage and waveform.
