ACCESS DOOR INSTALLATION

bracket holes.
4. Replace screws.
5. Make sure there is approximately
Fit access panel so it can be removed for maintenance.

SCREEN ADJUSTMENT

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 labaeled DOOR con-
trols 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.
