Caution
Do not operate the
motors 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.
First time operation
The first time you operate the screen, the protective paper
will fall out as the screen unrolls. Once the screen is fully
displayed, make sure that no packing paper remains on the
screen roll. The screen can be damaged if loose paper
remains.
First time activation for screen trigger interface
The STI input must be supplied with 12V DC power before
the main AC power is activated. Due to factory screen
packing procedures, the main screen roller may not be in
the fully up (motor off) position.
First time activation for horizontal screen
You must remove the shipping lockdown brackets. To do
this, operate the screen so that the door opens, then stop
the operation. Unscrew and remove the shipping lockdown
brackets.
The method you use to raise and lower the screen and mask depends on
the type of switch control device you have selected.
Use the masking screen as needed to establish the appropriate viewing
format.
When you lower or retract the screen or mask, they will stop at their preset
limits. 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 (or mask) 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.
