Adjusting the optical axis of the mirrors (M1, M5 and M4/M6)
The optical axis must be readjusted if an eclipse happens with the R. G or B mirrors. Generally speaking, this
adjustment is needed when any of the internal optical components has been replaced.
Adjustment procedure required when any of the panels has been replaced or the convergence has been
adjusted
(1) Disconnect the flat cables of all the LCD panels.
(2) Let the lamp light up.
(3) To adjust the G mirror, shield the R and B mirrors with shielding plates (You can use a business card or the like to
block the light).
(4) Loosen the lock screw of the M1 adjust lever.
(5) Looking at the G image on the screen, turn or slide the M1 adjust lever until the eclipse on the screen disappears.
Tighten up the screw.
(6) To adjust the R mirror, shield the G and B mirrors and adjust the M5 adjust lever. For the B mirror, shield the R
and G mirrors and adjust the M6 adjust lever. (Take the same steps 4 and 5 above.)
(7) Remove all the shielding plates to have a white image. Make sure there is no eclipse.

SAFETY NOTICE
Many electrical and mechanical parts in 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 the
service 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 the 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, metal halide 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 UV protective 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 BQC-PGC30X/1 rated 85V/200W.
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 in the Lamp Replacement Procedure and handle the lamp with care.

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 2.
[Use original replacement only.]
DANGER! –– 
Never turn the power on without the lamp to avoid electric-shock or damage
of the devices since the stabiliser generates high voltages at its start.
Since small amounts of UV-Radiation are emitted from an opening between the duct cover
and the lamp housing, it is recommended to place the LENS CAP on the opening during
servicing to avoid eye and skin exposure.
WARNING: 
High brightness light source, do not stare into the beam of light, or view
directly. Be especially careful that children do not stare directly in to the beam of light.
