I 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 iden-
tified 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 before any
service is performed on the projector.
2: Comply with all caution and safety-related notes provided on the cabinet back, cabinet bottom, inside the cabi-
net or on the chassis.
3: When replacing a chassis in the cabinet, always be certain that all the protective devices are installed proper-
ly, such as, control knobs, adjustment covers or shields, barriers, etc.
DO NOT OPERATE THIS PROJECTOR WITHOUT THE PROTECTIVE SHIELD IN POSITION AND PROPER-
LY 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 oper-
ate without danger of electric shock.
I SAFETY PRECAUTIONS
I 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 the 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 is 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(20~25kV) 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.
I SERVICE PERSONNEL WARNING
Pull out Battery Holder.
Replace with new battery. Install
with battery (+),() marks properly.
Install battery and
Battery Holder into
Remote Control Unit.
