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 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.
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.
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 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.

To insure safe operation, please observe the following precautions :
Do not expose a battery to moisture or heat. Do not charge a battery.
If a battery have leaked on Remote Cotrol Unit, carefully wipe the case clean and load a new battery.
Be sure to install battery with correct polarity.
CAUTION
Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.

Lamp Replacemant
When the life of Projection Lamp of this projector draws to an end, LAMP REPLACEMENT indicator lights yellow.
When a projected image becomes dark or the color of an image becomes unnatural, replacement of Projection
Lamp is required.
CAUTION CAUTION
For continued safety, replace with a lamp Do not drop a lamp assembly or touch a
assembly of the same type. glass bulb! The glass can shatter and
Allow a projector to cool for at least 45 may cause injury.
minutes before you open Lamp Cover.
The inside of a projector can become
very hot.
Follow these steps to replace the lamp assembly.
1. Turn off the projector and disconnect AC plug. Allow the projector LAMP COVER
to cool for at least 45 minutes.
2. Remove a screw with a screwdriver to remove Lamp Cover.
3. Remove 2 screws with a screwdriver and pull out Lamp Assembly
by grasping Handle.
4. Replace Lamp Assembly with a new one and tighten 2 screws
back. Make sure that Lamp Assembly is set properly. Replace
Lamp Cover and tighten a screw.
HANDLE
5. Connect AC Power Cord to the projector and turn it on.
6. Reset Lamp Replace Counter (refer to the section "Lamp Replace LAMP
Counter" below). ASSEMBLY
Do not reset Lamp Replace Counter when Projection Lamp is
not replaced.
LAMP REPLACE COUNTER
Be sure to reset Lamp Replace Counter when Lamp Assembly is replaced. When Lamp Replace Counter is
reset, LAMP REPLACE Indicator stops lighting.
1. Turn projector on, press MENU button and ON-SCREEN MENU will appear. Press POINT LEFT/RIGHT
button(s) to move a red frame pointer to SETTING Menu icon.
2. Press POINT DOWN button to move a red frame pointer to "Lamp counter reset" and then press SET button.
The message "Lamp replace counter reset?" is displayed. Move the pointer to [Yes] and then press SET button.
3. Another confirmation dialog box appears and select [Yes] to reset Lamp Replace Counter.
Do not reset Lamp Replace Counter except after Projection Lamp is replaced.

Protections
This projector is equipped with the following protections to operate in safety. If the abnormality occurs
inside the projector, it will turn off the projector by operating one of the following protections.
FUSE FOR CIRCUIT PROTECTION
The fuse is located on the ass'y-power. When either the
LAMP indicator or the READY indicator is not illuminated,
fuse may be opened. Check the fuse as following steps. Holder Power
1. Remove the ass'y-power following to "Mechanical Ass'y Power
Disassemblies".
2. Remove the fuse from fuse holder.
3. Check the resistance of fuse by using the tester.
To install the fuse, take reversed step in the above.
Fu
se
It should be used the specified fuse as parts list.
OVERHEATING PROTECTION (The temperature monitor system )
The temperature monitor system is provided to prevents damage of component parts inside the pro-
jector from overheat. Two protection systems are provided. Each system operating as follows.
Temperature monitor -1 :
When this function operates, warning-temperature-indica-
tor flashes. And cooling fan continues operating until it
becomes a normal temperature. If it continue to flush and
flash does not stopped, disconnect the AC cord and inves-
tigate the cause of overheating.
Press
Temperature monitor -2 :
(thermal switch SW902)
This function (thermal switch SW902) will not operate,
while the temperature monitor -1 is operating normally. If it
has operated, it needs to be reset manually. Disconnect Re
