CAUTION
Components indicated by a mark
in this schematic diagram have
the special significance in the safety. It is therefore, particularly rec-
ommended that the replacement of those parts must be made by
exactly the same parts. Must be used with a specified fuse. Unau-
thorized substitutions may result in fire or accident.
G
This projector 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 hot side (primary circuit) or both parts on
the hot and cold sides (secondary circuit) at the same time.
2. Do not shorten the circuit between hot and cold sides.
3. The grounding lead must be connected to the ground of the same
circuit when measuring the voltages and waveform.
