Safety precautions
The screen frames may be sharp. Hold the
parts carefully to avoid possible personal
injury or damage to the floor/product.
Make sure the wall for screen mounting
is stable enough to support the weight of
your ambient light rejecting (ALR) screen.
Never fold the screen material. Avoid
any scratches or wrinkles on the screen
material.
To protect the screen, always wear gloves
before touching or moving the screen
material.
Installation tips
Fix all screws halfway so you can make
adjustments easily. Tighten all screws after
adjustments.
Use appropriate tools to fix different
screws.
