Safety Instructions
Safety Precautions
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 identified with the line ( ) in the schematic diagram. For continued product safety and protection of per-
sonnel 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 before any service is performed on the projec-
tor.
2: Comply with all caution and safety-related notes
provided 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, adjust-
ment covers or shields, barriers, etc.
DO NOT OPERATE THIS PROJECTOR WITHOUT T
HE PROTECTIVE SHIELD IN POSITION AND PROP
ERLY SECURED.
4: Before replacing the cabinet cover, thoroughly
inspect 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
service personnel must be sure it is completely
safe to operate without danger of electric shock.
Service Personnel Warning
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.
Product Safety Notice
Product safety should be considered when a component replacement is made in any area of the projector.
Components 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 these
parts must be made by exactly the same parts.
