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 cir-
cuit is connected to the AC line and it is hot, which
hot circuit is identified with the line (
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 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 PROTECTIVE 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
service personnel must be sure it is completely safe
to operate without danger of electric shock.
PRODUCT SAFETY NOTICE

nent replacement is made in any area of the projec-
tor. Components indicated by mark
list and the schematic diagram designate compo-
nents 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.
