WARNING:
The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary side of the con-
verter 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 personnel injury, servicing
should be made with qualified personnel.
The following precautions must be observed.
SAFEtY PRECAUtIoNS
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 projector.
: 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.
DO NOT OPERATE THIS PROJECTOR WITHOUT THE PROTE
CTIVE SHIELD IN POSITION AND PROPERLY 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 serv-
ice personnel must be sure it is completely safe to oper-
ate 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 gener-
ates high voltages(15kV - 0kV) 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 spe-
cial significance. It is, therefore, particularly recommended that the replacement of there parts must be made by exactly
the same parts.
