This projection screen should be installed at the best possible viewing position for the audience.Take out 
all the parts from the packaging and follow the accessories guideline to ensure you have all parts.  The 
parts needed will vary depending on which installation you choose to use. For installation on a  wood wall 
or ceiling, use the    5 x 40 screws. For installation on a drywall, use the    10 x 30 screws with anchors.

Wall Mount

Using a tape measure, measure the distance between the two keyholes on the casing ( Figure 1 ).  According 
to the measurement, drill identical holes of the appropriate size ( use a smaller drill bit than the actual screws) 
on the wall and ensure that it is level ( Figure 2 and 3 ). Screw in the appropriate screws, either the    5 x 40 for 
wood walls or the    10 x 30 plus anchors for drywalls, leaving enough space at the end to hang the casing 
( Figure 4 ). To ensure that the screen is level, use a leveler to check ( Figure 5 ). 

Ceiling Mount

Measure the distance between the two rings for hanging on the casing ( Figure 1 ). According to the measurement, 
drill identical holes of the appropriate size (use a smaller drill bit than the actual hook screws) on the ceiling and 
ensure that it is level ( Figure 2 and 3 ). Screw in the hook screws (not provided), and lift the screen into the hooks 
screws to hang ( Figure 4 ). To ensure that the screen is level, use a leveler to check ( Figure 5 ).
