CAUTION
Fuse of the specified parts number must be used.
Unauthorized substitutions may result in fire or accident.
CAUTION
Components indicated by a mark in this schematic diagram designate
K
components in which safety can be of special significance. It is, therefore,
particularly recommended that the replacement of these parts must be
made by exactly the same parts.
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
hot and cold sides (secondary circuit) at the same time.
L
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 of voltages and waveforms.
