Components indicated by a mark 

! 

in this schematic diagram designate 

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 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 

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 of voltage and waveforms.
