Installing the Projector
The high quality display effect can be guaranteed only when the projector is correctly installed. Generally, the light
source facing the screen should be reduced or eliminated as much as possible. The contrast of the image will be
obviously reduced if the light directly shines on the screen, such as the beam from windows or the searchlight cast on
the image. The image may become faded and not bright. Before installation, recommend to eliminate the effect of
ambient light. Beside the projection performance, please read below precaution for installation carefully.
Precautions for Installation
Projector installation must be done by a qualified professional. Contact your dealer for more
information. It is not recommended you install the projector yourself.
With ceiling installation, use approved mounting hardware & M4 screws; maximum depth of screw: 14
mm. Contact your dealer for information about mounting the projector on a ceiling.
Only use the projector on a solid, level surface, serious injury and damage can occur if the projector is
dropped
Ensure that the hot air from the exhaust vent is not sucked into the projector.
Ensure the air intake and exhaust vents are unobstructed and keep the required distance from any
object. Below is required minimum distance between the vent and any object.
All added enclosures should pass a certified thermal evaluation to ensure that the projector does not
recycle exhaust air, as this may cause the projector to stop projection even if the enclosure temperature
is with the acceptable operation temperature range.

Installing or Removing the Optional Lens
Before removing or installing the lens, be sure to turn off the projector and wait till the cooling fans
stop, and turn off the main power switch.
Do not shake or place excessive pressure on the projector or the lens components as the projector
and lens components contain precision parts.
Be sure to remove the optional lens before shipping the projector. The lens and the lens shift
mechanism may encounter damage caused by improper handling during transportation.
Do not touch the lens surface when removing or installing the lens.
Keep fingerprints, dust or oil off the lens surface. Do not scratch the lens surface.
Work on a level surface with a soft cloth under it to avoid scratching.
If you remove and store the lens, attach the lens cap to the projector to keep off dust and dirt.
When installing the lens into the projector, be sure to remove the lens cap from the back of the
optional lens, the cap would block the light and be melted. Failure to do so will cause damage to the
projector and lens.
Install New Lens
1. If the Lens cover is installed, pull the edge of the lens cover with one hand ( ①), so that the lens cover can be
removed easily with the other hand ( ②)
2. Align the "" symbol on the lens label with the "* " symbol on the top of the body (align to the center of the lens
hole) and pull in the lens.

Setting up the Cooling Condition
The high quality display effect can be guaranteed only when the projector is correctly installed. Generally, the light
source facing the screen should be reduced or eliminated as much as possible. The contrast of the image will be
obviously reduced if the light directly shines on the screen, such as the beam from windows or the searchlight cast on
the image. The image may become faded and not bright.
Beside projection performance, the installation orientation would affect heat dissipation for the projector. Improper
cooling conditions may shorten the life of light source or damage the components inside the projector. Please set the
correct Cooling Condition on OSD menu according to the installation orientation.
