There is 3% tolerance among these numbers due to optical component variations. It is
recommended that if you intend to permanently install the projector, you should physically
test the projection size and distance using the actual projector in situ before you permanently
install it, so as to make allowance for this projector's optical characteristics. This will help you
determine the exact mounting position so that it best suits your installation location.
Shifting the projection lens vertically
The vertical lens shift control provides flexibility for installing your projector. It allows the
projector to be positioned slightly above or below the top level of the projected images.
Use the wheel to shift the projection lens upwards or downwards within the allowable range
depending on your desired image position.
To use the lens shift wheel:
Turn the wheel to adjust the projected image position.
Do not over-tighten the wheel.
Lens shift adjustment does not result in a degraded picture quality.
