8. Check if the lens is really secured by trying to pull the lens out of the lens holder.
CAUTION:Never transport the projector with a Lens mounted in the Lens Holder. Always remove the Lens
before transporting the projector. Neglecting this can damage the Lens Holder and Prism.

3.2.4 Lens removal
How to remove
1. Support the lens with one hand while you unlock the lens holder bysliding the lock handle towards the “unlocked” position as
illustrated.

2. Gently pull the lens out of the lens holder.

Lens removal
It’s recommended to place the Lens caps of the original Lens packaging, back on both sides of the removed
Lens to protect the optics of the Lens.
It’s recommended to place the foam rubber of the original projector packaging, back in the Lens opening to
prevent intrusion of dust. Note that this foam rubber is packed in a plastic bag to prevent the dust, emitted by
the foam, from entering the projector.

3.2.6 Scheimpflug adjustment
What has to be done ?
The lens holder has to be adjusted so that the “sharp focus plane” ofthe projected image falls together with the plane of the screen
(Fp1→Fp2). This is achieved by changing the distance between the DMD plane and the lens plane (Lp1→Lp2). The closer the lens
plane comes to the DMD plane the further the sharp focus plane will be. It can sometimes happen that you won’t be able to get a
complete focused image on the screen due to a tilt (or swing) of the lens plane with respect to the DMD plane. This is also known
as Sheimpflug’s law. To solve this the lens plane must be placed parallel with the DMD plane. This can be achieved by turning the
lens holder to remove the tilt (or swing) between lens plane and DMD plane (Lp3→Lp4).

Scheimpflug principle
The plane of sharp focus can be changed so that any plane can be brought into sharp focus. When the DMD plane
and lens plane are parallel, the plane of sharp focus willalso be parallel to these two planes. If, however, the lens
plane is tilted with respect to the DMD plane, the plane of sharp focus will also be tilted according to geometrical and
optical properties. The DMD plane, the principal lens plane and the sharp focus plane will intersect in a line below the
projector for downward lens tilt.

Necessary tools
• Allenkey3mm
• Nut driver 13 mm
• Nut driver 10 mm
How to adjust
1. Project a green focus pattern.
Image 3-33
2. Loosen the lock nuts (a, b, c and d). See image 3-32.
3. Loosen the 4 set screws (A, B, C and D) by 1 cm. See image 3-32.
4. Fully loosen lock nut 4. See image 3-32.
5. Optimize the focus of the projected image as follows:
a) Place the zoom lens in TELE position (smallest projected image) and adjust the focus using the lens focus barrel or motorized
focus control.
b) Place the zoom lens in WIDE position (largest projected image) and adjust the focus by turning equally on nut 1, 2 and 3.
c) Repeat steps “a” and “b” until the projected image is as sharp as possible.

How tofixtheScheimpflug
Start thefixation as follows (steps must be followed strictly) :
1. Turn in set screw A, B and C. Tighten lightly (by hand).
Tip:Any movement of the image will affect the Scheimpflug adjustment
2. Fasten lock nuts a, b and c.
3. Turn in set screw D lightly (by hand) allowing the image to move slightly (1/3 to 1/2 of a square).
1/3 to 1/2
Image 3-38
4. Fasten lock nut d.
5. Tighten nut 4 until the offset of the image movement created in step 3 is canceled.
Tip:The amount of image movement in step 3 will determine how tight the nut in step 5 will need to be turned to return the
image to its original position.

3.3 Connecting the projector with the power net
CAUTION:Use only the power cord provided with the projector.
How to connect with local power net
1. Ensure that the power switch stands in the ’0’ (OFF) position (1).

Power input
2. Connect the female side of the power cord with the power input socket of the projector (2).
3. Secure the power plug by locking the plug holder clamp (3).
4. Connect the male side of the power cord to the local power net.
Caution:Ensure that the power net meets the power requirements of the projector.
WARNING:Do not attempt operation if the ACsupply and cord are not within the specified voltage and power
range.
CAUTION:Once the projector is switched to standby, the lamp cooling fans will continue to run for approx-
imatelyfive minutes to ensure that the projector and lamp have sufficiently cooled, at which point the fans
will automatically decrease to standby. To avoid thermal stress that can lead to premature lamp failure, never
unplug the power cord while the lamp cooling fans are running. Never unplug the power cord to power down
the projector,first switch off the power switch and then unplug the power cord.
Fuses
The projector is protected with an automatic circuit breaker of 20 A which is built into the power switch.
The voltage meter is protected with a fuse (1A) which is located on the neutral bonding cable. If necessary to replace this fuse,
consult a service technician.

3.4 Alignment of a table mounted projector
How to align
1. Place the projector in the desired location. Take into account the zoom range of the used lens and the size of the screen.
2. Project one of the internal hatch patterns on the screen.
3. Turn the adjustable feet in or out until the projected hatch pattern has a perfect rectangle shape and is leveled.
Image 3-40
Level alignment
When this is achieved, the projector is set horizontal and vertical at right angles to the screen.
