The picture surface drop, and the opening and closing of the fabric door, are controlled automatically by limit switches which have been preset
at Da-Lite. When the picture surface is moving upward, it is controlled by a limit switch that shuts off when the door closes. To adjust for more or
less picture drop (viewing area), proceed in the following manner:
Screen Unrolled in "Down" or "Bottom" Position.
NOTE: Limit switch knob labeled DOWN controls point of picture
surface in bottom position. Limit switch knob labeled DOOR controls
the synchronization of the door opening or closing. Do not adjust!
More screen drop
1. Place operating switch in “down” position.
2. When the screen stops, turn the “down” limit knob one turn at
a time clockwise, until the desired picture surface position is
attained. Test by raising picture surface approximately two
feet, then lower again. Repeat until desired picture surface
position is attained.
CAUTION! When picture surface is in "Bottom" position,
do not adjust for more than 3" of additional drop. Do not
allow any part of the roller to become exposed.
ATTENTION! Lorsque la surface de projection est sur la
position "Bas", ne déroulez pas la toile plus de 7,6 cm (3
po). N'exposer aucune partie du rouleau.
