SAFETY PRECAUTION
IMPORTANT SERVICE SAFETY NOTES
IMPORTANT SERVICE SAFETY NOTES
Service work should be performed only by qualified service technicians who are
thoroughly familiar with all safety checks and servicing guidelines as follows:
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE PROJECTOR:
(Fire & Shock Hazard)
Before returning the projector to the user, perform
the following safety checks:
1. Inspect lead wires are not pinched between the chassis
and other metal parts of the projector.
2. Inspect all protective devices such as non-metallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacity networks, mechanical
insulators, etc.
3. To be sure that no shock hazard exists, check for
current leakage in the following manner:
Plug the AC cord directly into a 120 - volt AC outlet,
(Do not use an isolation transformer for this test).
Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in parallel
between all exposed metal cabinet parts and earth
ground.
Use an AC voltmeter with sensitivity of 5000 ohm per
volt., or higher, sensitivity to measure the AC voltage
drop across the resistor.
All checks must be repeated with the AC plug
connection reversed. (If necessary, a non-polarized
adapter plug must be used only for the purpose of
completing these checks.)
Any reading of 0.4 volts RMS (this corresponds to 0.27
milliamp. AC.) or more is excessive and indicates a
potential shock hazard which must be corrected before
returning the unit to the owner
.
SAFETY NOTICE
Many electrical and mechanical parts in DLP
Projector have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
components having such features are identified by “
and shaded areas in the Replacement Parts Lists and
Schematic Diagrams. For continued protection,
replacement parts must be identical to those used in
the original circuit. The use of a substitute replacement
parts which do not have the same safety characteristics
as the factory recommended replacement parts shown
in this service manual, may create shock, fire or other
hazards.
WARNING: The bimetallic component has the primary
conductive side exposed. Be very careful in
handling this component when the power is on.

NOTE TO SERVICE
PERSONNEL
UV-RADIATION PRECAUTION
The light source, lamp, in the projector emits small
amounts of UV-Radiation.
AVOID DIRECT EYE AND SKIN EXPOSURE.
To ensure safety please adhere to the following:
1. Be sure to wear sun-glasses when servicing the
projector with the lamp
turned “on” and the top
enclosure removed.
2. Do not operate the lamp outside of the lamp housing.
3. Do not operate for more than 2 hours with the enclosure
removed.
UV-Radiation and Medium Pressure
Lamp Precautions
1. Be sure to disconnect the AC plug when replacing the
lamp.
2. Allow one hour for the unit to cool down before
servicing.
3. Replace only with same type lamp. Type AN-XR30LP
rated 200W DC.
4. The lamp emits small amounts of UV-Radiation, avoid
direct-eye contact.
5. The medium pressure lamp involves a risk of explosion.
Be sure to follow installation instructions described
below and handle the lamp with care.

Lamp
Reflector
Since small amounts of UV-radiation are emitted
from an opening between the exhaust fans, it is rec-
ommended to place the cap of the optional lens on
the opening during servicing to avoid eye and skin
exposure.
DANGER ! –– Never turn the power on without the
lamp to avoid electric-shock or damage of the devices
since the stabilizer generates high voltages at its start.
UV-RADIATION PRECAUTION (Continued)
Lamp Replacement
Note:
Since the lamp reaches a very high temperature during
units operation replacement of the lamp should be
done at least one hour after the power has been turned
off. (to allow the lamp to cool off.)
Installing the new lamp, make sure not to touch the
lamp (bulb) replace the lamp by holding its reflector
.
[Use original replacement only.]

Precautions for using lead-free solder
„
Employing lead-free solder
• "PWBs" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The
alphabetical character following LF shows the type of lead-free solder. 
Example:
„
Using lead-free wire solder
• When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause dam-
age or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 
°C, we recommend you to use a dedicated soldering
bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
„
Soldering
• As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 
°C which is higher than the conventional lead solder by 40 °C, and as it has poor
solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may be
peeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the
steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and off the power of the bit as
required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
• Be careful when replacing parts with polarity indication on the PWB silk.
