■ 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 person-
nel 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.
DO NOT OPERATE THIS PROJECTOR WITHOUT
THE PROTECTIVE SHIELD IN POSITION AND
PROPERLY SECURED.
2: Comply with all caution and safety-related notes
provided on the cabinet back, cabinet bottom, inside
the cabinet or on the chassis.
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.
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.
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
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 there
parts must be made by exactly the same parts.
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 - 20kV) 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.

■ Circuit Protections
This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the
projector, it will automatically turn off by operating one of the following protection circuits.
●
Fuse
A fuse(F601) is located inside of the projector. When
the POWER indicator is not lightning, the fuse may be
opened. Check the fuse as following steps.
The fuse should be used with the following type;
Fuse (F601)
Fuse Part No. : 323 022 2105
TYPE T4.0AH 250V FUSE
LITTEL FUSE INC. TYPE 215004
How to replace the fuse
1. Remove the cabinet top and main board following to
"Mechanical Disassemblies".
2. Remove the fuse from fuse holder on the Filter
Board.
To install the fuse, take reversed step in the above.
●
Thermal switch
There is the thermal switch (SW902) inside of the pro-
jector to prevent the internal temperature rising abnor-
mally. When the internal temperature reaches near
90°C, the thermal switch cuts off the drive signal to the
lamp circuit automatically. The thermal switch is not
reset to normal automatically, even if the internal tem-
perature becomes normal. Reset the thermal switch fol-
lowing procedure.
Check the resistance between terminals of thermal
switch by using a tester. If it has high impedance, ther-
mal switch may be open.
Press
Thermal switch
(SW902)
How to reset the thermal switch
1. Remove the cabinet top ass'y following to
"Mechanical Disassemblies".
2. Press the reset button on the thermal switch with a
sharp-pointed tool.
CAUTION:
Before press the reset button, make sure that the AC
cord must be disconnected from the AC outlet.
