Safety
1. Read and understand instructions and heed warnings before beginning installation.
2. Mount rail securely. The lens is heavy, and requires a secure and stable surface.
Fasteners in sheetrock alone are not safe. Reciprocal lens motion can and will work
them loose. Use a board, plate, or projector mount fixed to ceiling joists or studs.
3. Anticipate unexpected lens motion. A malfunction can cause the lens to move
unexpectedly. Disconnect the power when installing, working on or repositioning
the lens. While on a ladder, do not stand in the direct path of the lens in case of
unexpected or accidental movement.
4. Do not install the lens in a wet or moist environment, or where the mechanism will be
exposed to extreme or external weather conditions. The lens is for indoor use only.
5. Never pour any liquid or push any object into the enclosure.
6. Do not install in direct path of heater vents or projector exhaust ports. Do not block
any of the vents or holes in the enclosure.
7. The power adaptor is intended for 100- 220 volt, 50-60 cycle AC power only.
8. Do not subject power cord to conditions which will wear through or cut the insulation.
Avoid excessive tension or chafing of the cord.
9. Do not service the motor drive or electronics. There are no user serviceable parts.
Contact your dealer or send to a factory approved facility. Opening the case will void
the warranty.
10. Exercise extreme caution when working on a ladder. Do not work directly above
another person, particularly a child. Plan all work carefully. Accidentally dropping a
drill, hammer, or the lens assembly can cause serious bodily injury.
11. Pushing or forcing the sled by hand may damage the circuit board. Should it be
necessary to move the sled by hand, make sure it is done slowly and lightly.
12. The Optoma motorized sled will ramp up and down at the beginning and end of the
traversal to minimize swaying forces at the mount. As the motor accelerates and
brakes, there is a minimal change in the sound.
This device complies with part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.

Plan Your Installation
The lens assembly may be mounted in one of two ways:
1. To the ceiling or projector mount above the projector
2. To a shelf or table below the projector
When attaching the motor assembly to the ceiling, use a board, plate or lens-enabled projector mount
that is attached to ceiling joists or studs. Sheetrock embedded fasteners can and will become loose
with repeated lens movement, causing the mechanism to fall, resulting in possible severe injury.
Planning for Projector Exhaust
Some projectors have hot air exhaust ports that discharge from the front. Avoid situations where the
lens or housing will block or obstruct the warm air flow out of the projector, as damage to the bulb
and/or the lens may result. You can mount the sled either to the left or right of the lens. During setup,
you can easily configure the “lens-in” position to be on the motor housing or pulley housing side of the
sled. (See Setup).
Changing Orientation of Logo Plate (Optional)
The lens sled is configured for ceiling mounted operation as shipped. As such, the
logo reads right side up with the mounting bar on top. If you are using the
sled in a table or shelf mounted
configuration, you will want to turn
the logo around so that it is right
side up with the mounting bar
below the projector.
To reverse the logo, remove the 4
screws securing the motor housing
cover. Lightly slide the sheet metal
cover and lift it off. Once removed,
you can easily access the logo
plate. Remove the two small
screws securing the logo plate,
turn the plate around, and re-install
the screws. Install the motor cover
housing back on the sled with the
original screws.
The logo backlight may be turned
off using the remote control. An
alternative to reversing the logo
plate is to simply turn off the
back light to make the logo less
conspicuous.

Mounting Sled to Shelf or Ceiling
When installing the motorized sled, make sure that you first mark screw locations using
only the sled−without the lens and/or the lens bracket in place.
Do not rely on fasteners embedded in sheetrock alone. Reciprocal lens movement can
and will work them loose and cause the mechanism to fall. Mount the sled on a plate,
board, or lens-enabled projector mount affixed to ceiling joists for safety.
Once the sled is secure, attach the bracket to the lens adaptor plate. Then, only after
properly aligning and positioning the bracket, power up the sled and check the alignment
again. Finally, attach and adjust the lens to its correct angle and vertical position.
Follow this procedure:
1. Line up the center line of lens
There are score marks on the back of the mounting bar that correspond to the center of
the BX-AL133 expansion lens. Before starting, the projector must be correctly focused
with the zoom and iris set in their viewing positions. This will assure that the front of the
lens is positioned correctly. Hold the motorized sled up to the projector and determine
if the LENS IN position will be on the motor housing (logo side) or the pulley housing
(smaller box) side. This will determine the score mark you will use (see below).
Measure 2-1/8 inches from the front of the projector lens, and lightly draw a line parallel
to the front of the lens. Mark the center line of the projector lens along this parallel line.
Line up the back of the mounting bar to the parallel line just marked. Align the center of
the projector lens mark with the correct score line on the mounting bar, and mark the six
drill hole locations using the mounting bar itself as a template. Drill out the holes for the
fasteners.
