Nortel Networks 83c User Manual

If the image is too high or low, you can correct it by adjusting the 
projector’s front foot. 

1. Stand behind the projector. Press up on the blue foot release lever 

and lift the front of the projector to extend the front adjustable 
foot.

2. Once the image is positioned where you want, release the lever to 

lock the foot in position.

The projector automatically corrects images that are distorted when 
the projector is tilted up or down (up to a 30° tilt). The Keystone 
window appears on the screen while the projector makes the 
correction. If the projected image still isn’t rectangular, follow the 
instructions in the next section.
