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 trans-
former. 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.
L
3. The grounding lead must be connected to the ground of the same circuit
when measuring the voltages and waveform.
