Model B & Model C Electriscreens: Owner’s Manual
9
The extension and retraction limits have been preset at the factory. In
general, we advise you to avoid readjusting these limits.
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.
Caution
Improper adjustment of the limits 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 blue retraction (UP) thumbwheel that will further retract
the screen. Incorrect adjustment of the thumbwheel will
cause severe screen damage. Please consult the factory if
you have any questions.
