SCREEN ADJUSTMENT

Surface travel is stopped automatically in the fully opened and closed positions by limit switches that are properly

adjusted at DA-LITE. Should it be necessary to adjust for more or less picture drop (viewing area), proceed in the

following manner:

NOTE: Use a screwdriver or allen wrench to make adjustments.

MORE SCREEN DROP

1. Place operating switch in "down" position.

2. When the screen stops, turn the white "down" limit knob (Fig. 3) one-quarter turn counter-clockwise. Test by raising

picture surface approximately two feet, then lower again. Repeat until desired picture surface position is attained.

LESS SCREEN DROP

1. Raise picture surface approximately two feet above desired level.

2. Place operating switch in "off" position.

3. Turn the white "down" limit knob one-quarter turn clockwise. Test by raising picture surface approximately two feet,
