Important Safety Instructions
When using your video equipment, basic safety precautions should always be followed, including the following:
1. Read and understand all instructions before using.
2. Position the cord so that it will not be tripped over, pulled, or
contact hot surfaces.
3. If an extension cord is necessary, a cord with a current rating at
least equal to that of the appliance should be used. Cords rated
for less amperage than the appliance may overheat.
4. To reduce the risk of electric shock, do not disassemble this
appliance. Contact an authorized service dealer when repair
work is required. Incorrect reassembly can cause electric shock
when the appliance is used subsequently.
5. The use of an accessory attachment not recommended by the
manufacturer may cause a risk of ire, electric shock, or injury to
persons.

Pre-Installation
1. Carefully unpack screen.
2. Make sure to recheck measurements of screen location
before installation.

Without Hangers
Screen case is placed lush with
the wall and ceiling and held in
position by moulding securely
attached to the wall.
Recessed Above Ceiling
Other methods of installation
will suggest themselves in new
buildings where it would be an
easy matter to provide a recess
for the screen to conceal it when
not in use.
Do not seal in—allow access.
Wall or Ceiling Mount With Hangers
Wall type hangers and ceiling type hangers are
standard equipment. One set is supplied with
each screen. Useful for recessed installations.
