CAUTION<br />
Components indicated by a mark ! in this schematic diagram have the special significance<br />
in the safety. It is therefore, particularly re<strong>com</strong>mended that the replacement<br />
of those parts must be made by exactly the same parts. Must be used with a specified<br />
fuse. Unauthorized substitutions may result in fire or accident.<br />
This projector is isolated from AC line by using the internal converter transformer.<br />
Please pay attention to the following notes in servicing.<br />
1. Do not touch the part on hot side (primary circuit) or both parts on the hot and cold<br />
sides (secondary circuit) at the same time.<br />
2. Do not shorten the circuit between hot and cold sides.<br />
3. The grounding lead must be connected to the ground of the same circuit when measuring<br />
the voltages and waveform.<br />
