Schematic Diagrams

CAUTION

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.

CAUTION

Fuse of the specified parts number must be used.

Unauthorized substitutions may result in fire or accident.
