UTION
Components indicated by a mark
in this schematic diagram have the special sig-
nificance in the safety. It is therefore, particularly recommended that the replacement
of those parts must be made by exactly the same parts. Must be used with a specified
fuse. Unauthorized substitutions may result in fire or accident.
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 mea
-
suring the voltages and waveform.
