CAUTION
Components indicated by a mark 7 in this schematic diagram have the spe-
cial significance 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 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.
3. The grounding lead must be connected to the ground of the same circuit
when measuring the voltages and waveform.
CAUTION
Fuse of the specified parts
number must be used.
Unauthorized substitutions may
result in fire or accident.
Fuse of the specified parts
number must be used.
Unauthorized substitutions may
