down several times. Be prepared to stop screen.
6. Check for satisfactory condition by running screen a
few times.
NOTE: The picture surface, when rolled down, should
have a full wrap around the roller. Do not allow any part
of the roller to become exposed.
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 (viewing area), proceed in the following manner:
More Screen Drop
1. Place operating switch in “down” position.
2. When the screen stops, turn the “down” limit knob one-
quarter turn clockwise.
3. Test by raising picture surface approximately two feet, then
lower again. Repeat until desired drop is attained.
CAUTION! When screen is in bottom position, do not
adjust for more than 3" of additional drop. Roller should
not be 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.
Less Screen Drop
1. Raise picture surface approximately two feet above desired
level.
2. Place operating switch in “off” position.
3. Turn the “down” limit knob one-quarter turn
counterclockwise.
4. Test by raising and lowering picture surface.
5. Repeat steps 3 and 4 until desired drop is attained.
NOTE: Limit “down” switch knob controls stopping point of
