This illustration is not drawn to scale.
C a u t i o n :
• All construction work should be done by a qualified technician.
• When mounting to the ceiling, use the special mounting bracket. To prevent the projector from swaying or dropping, attach the wire that is included with the projector between the mounting bracket and the ceiling.

* Lens performance cannot be guaranteed for projection sizes larger than 11.0 m (36.1 ft).
NOTE:
P
• The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
• At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
PT-LX22
Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4:3 minimum L (m) = (diagonal screen size in inches) × 0.0345 – 0.0233
maximum L (m) = (diagonal screen size in inches) × 0.0414 – 0.0237
NOTE:
Distances calculated with the above equations will include a slight error.
Installable angle
Install the projector at an angle within the range shown below.
• Vertical direction
The projector may be installed at a vertical angle of 30°.
• Horizontal direction
The projector may be installed at a horizontal angle of 20°.

List of compatible signals
The signals that can be input to this projector are shown in the table below. Horizontal scanning frequencies of 15 kHz to 100 kHz, vertical scanning frequencies of 50 Hz to 100 Hz, and a dot clock of
140 MHz maximum can be input.
NOTE: The native resolution of this projector is 1,024 × 768 pixels. If the display resolution of the input signal is different from the native resolution, image compression or expansion will be used to convert the input signal to a level within the native resolution.

CAUTION
• It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this occurs, wait for 60 seconds, then try sending or receiving again.
• When sending multiple commands, be sure to wait for at least 0.5 second after receiving a response from the projector before sending the next command.
• Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for command response to 10 seconds or more.

Notes on projector placement and operation
The projector uses a high-wattage lamp that becomes very hot during operation. Please observe the following precautions.
1.
Never place objects on top of the projector while it is operating.
2.
Make sure there is the unobstructed space as shown below or more around the projector’s exhaust openings. In addition to this space, also ensure that there is a sufficient work space for removing and installing the lamp, filter and other parts.
3.
Make sure that nothing blocks the projector’s air intake and exhaust openings. Also, install the projector so that cool or hot air from other air conditioning equipment does not flow directly toward the projector’s air intake or exhaust openings.
4.
Do not install the projector in an enclosed space. If it is necessary to install it in an enclosed space, add a separate ventilation system. If ventilation is insufficient, hot air will accumulate at the intake opening. This may cause the projector’s protective circuit to interrupt projector operation.

Operating the projector continuously
1. If the projector is to be operated continuously 6 hours or more, lamp replacement cycle duration becomes shorter.
2. The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short periods (one hour or less).
