ADJUSTING THE SCREEN EXTENSION
i
CAUTION
Improper adjustment of the limit switches can cause irreparable damage to the screen itself, resulting
in voiding the factory warranty
The extension and retraction limit switches have been preset at the factory In general, we advise you
to avoid readjusting these switches In some cases, to enable proper alignment of the displayed image
on the screen, you may need to adjust the extension of the screen If adjustment to the extension is
necessary, carefully follow these instructions
WARNING!
The screen is fully retracted when the batten is flush with the bottom of the case Do not attempt
adjustments with the yellow retraction (UP) limit switch that will further retract the screen Incorrect
adjustment of the switch will cause severe screen damage Please consult the factory if you have
any questions
ADJUSTING THE SCREEN EXTENSION
The standard preset black drop is 6”; this should not be reduced less than 2” of black drop visible Please
refer to your specifications on your maximum black drop allowed
WARNING!
Do not attempt to modify the screen extension beyond these recommended amounts There is
a line printed on the screen material that warns you where not to exceed the black drop Going
beyond this line could result in damage to the screen
To increase the screen’s fully extended (screen down) stop position:
1 Lower the screen to its current stop position
2 Remove the dust cover to locate the white extension (down) limit switch on the left side of the
screen tube (audience left) Use a small electrician’s style screwdriver or a 5/32” ( 4 cm) hex wrench
to turn the switch in a counterclockwise direction If the power is still on, the screen will drop incre-
mentally as the switch is turned
Note:
One complete turn of the switch will make approximately a 3/4” (2 cm) change in the screen’s
stop position
