1. Attach the wall brackets to the wall using appropriate
fasteners at previously marked locations.
When you lower or retract a mask, it will stop at its present limit.
If an obstacle (such as a person or furniture) gets in the path of a
mask as it is lowered, you should use the switch control to stop
the mask's motion; it will not automatically stop if it hits an
obstacle.
NOTE: The horizontal masking panels move more slowly than
the vertical masking panels. The slower motion allows you to
adjust the image area with greater precision.
When a mask is not in use, you should store it in the fully
retracted position.
CAUTION: Do not operate the motor when any of the
following occurs:
• The unit emits any smoke, heat, abnormal noise
or unusual odor.
• The unit is damaged in some way, such as damage from a
water leak.
• If any of these situations occur, call a qualified
service person.
ATTENTION: Ne mettez pas le moteur en marche lorsque :
• L'unité émet de la fumée, un bruit anormal, de la chaleur
ou une odeur inhabituelle.
• L'unité est endommagée d'une quelconque façon (ex.
dommage dы а une fuite d'eau).
• Si l'une de ces situations se produisait, appelez un
technicien qualifié.
CAUTION: Improper adjustment of the limit switches
can cause irreparable damage to a mask itself, resulting
in voiding the factory warranty.
ATTENTION: Un réglage inapproprié des interrupteurs de
fin de course peut endommager de manière irréversible le
masque et entraîner l'annulation de la garantie.
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 a mask. If adjustment to the extension is necessary, carefully
follow these instructions.
WARNING! A mask is fully retracted when the batten
is flush with the bottom of the case. Do not attempt
adjustments with a retraction (UP) limit switch that will
further retract a mask. Incorrect adjustment of that
switch will cause severe mask damage. Please consult the
factory if you have any questions.
AVERTISSEMENT! Un masque est complètement rétracté
lorsque la latte est alignée avec le bas du caisson.
N'essayez pas d'effectuer des réglages avec un
interrupteur de fin de course d'enroulement (VERS LE
HAUT) qui causera une rétraction additionnelle d'un
masque. Un réglage incorrect de cet interrupteur peut
endommager sérieusement le masque. Veuillez contacter
l'usine si vous avez des questions.
