• There is an error of 

Ⳳ3% in the formula above.

• Values with a minus (

ⳮ) sign indicate the distance of the lens centre below the bottom of the screen.

Position the projector perpendicular to the screen with all feet flat and level to achieve an optimal image.
Move the projector forward or backward if the edges of the image are distorted.

• The projector lens should be centred in the middle of the screen. If the lens centre is not perpendicular to the screen, the image will be

distorted, making viewing difficult.

• Position the screen so that it is not in direct sunlight or room light. Light falling directly onto the screen washes out colours, making viewing

difficult. Close the curtains and dim the lights when setting up the screen in a sunny or bright room.

• A polarizing screen cannot be used with this projector.

Place the projector at the required distance from the screen according
to the desired picture size (see the table below).
