Safety Instructions
WARNING:
The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary side of
the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot circuit is identi-
fied with the line (
) in the schematic diagram. For continued product safety and protection of personnel injury,
servicing should be made with qualified personnel.
The following precautions must be observed.
1: An isolation transformer should be connected in the
power line between the projector and the AC line be-
fore any service is performed on the projector.
2: Comply with all caution and safety-related notes pro-
vided on the cabinet back, cabinet bottom, inside the
cabinet or on the chassis.
3: When replacing a chassis in the cabinet, always be
certain that all the protective devices are installed
properly, such as, control knobs, adjustment covers
or shields, barriers, etc.
Product safety should be considered when a component replacement is made in any area of the projector. Com-
ponents indicated by mark ! in the parts list and the schematic diagram designate components in which safety
can be of special significance. It is, therefore, particularly recommended that the replacement of there parts must
be made by exactly the same parts.
Eye damage may result from directly viewing the light produced by the Lamp used in this equipment. Always turn
off Lamp before opening cover. The Ultraviolet radiation eye protection required during this servicing.
Never turn the power on without the lamp to avoid electric-shock or damage of the devices since the stabilizer
generates high voltages (15kV - 25kV) at its starts.
Since the lamp is very high temperature during units operation replacement of the lamp should be done at least
45 minutes after the power has been turned off, to allow the lamp cool-off.
Safety Precautions
DO NOT OPERATE THIS PROJECTOR WITH-
OUT THE PROTECTIVE SHIELD IN POSI-
TION AND PROPERLY SECURED.
4: Before replacing the cabinet cover, thoroughly in-
spect the inside of the cabinet to see that no stray
parts or tools have been left inside.
Before returning any projector to the customer, the ser-
vice personnel must be sure it is completely safe to op-
erate without danger of electric shock.
