The method you use to raise and lower the screen depends on the type of
switch control device you have selected.
When you lower or retract the screen, it will stop at its preset limit. If an
obstacle (such as a person or furniture) gets in the path of the screen as it
is lowered, you should use the switch control to stop the screen's motion; it
will not automatically stop if it hits an obstacle.
The motor is designed to be used for short operations such as lowering the
screen in preparation for viewing. The motor is not designed for continuous
duty. If the motor operates continually for more than a few minutes, it may
automatically shut off to prevent damage from overheating. If the motor
occasionally needs to be run more than normal, for example during initial
setup and positioning, allow time for the motor to cool down.
In general, when the screen is not in use, you should store it in the fully
retracted position.
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.

Improper adjustment of the limit switches can cause
irreparable damage to the screen itself, resulting in voiding
the factory warranty.
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.
