and down several times. Be prepared to stop screen. Standard

Duty Cycle: 1 MIN. ON / 3 MIN. OFF.

up the limit switch (in the motor) is tripped and the motor shuts off.

mask will start down off the front of the roller, travel completely

down past the bottom of the viewing surface, then "step back"

against the viewing surface to eliminate shadowing by rolling up

the back side of the roller. Do not adjust the limits to change this

feature.
