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 drop of picture, proceed in the following manner:

NOTE: 

Use a screw driver or 5/32" 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.4) one-quarter turn counterclockwise. 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 (Fig.4) one-quarter turn 

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

 

CAUTION! Do not adjust for more drop than what was 
ordered. At least 1-1/2 wraps of fabric must remain on the 
roller. This screen comes standard with 0" or 2" black at 
the top. See the specification data sheet for details.
