5.  As screws are tightened, the plastic mounting clips will rotate clockwise and draw in 

against the inside of the wallboard.  If using a drill to tighten screws, tighten all four until 
the speaker frame just makes contact with the ceiling.  From there, it is best to use a 
hand screwdriver to fully tighten.  This will prevent breakage of the plastic mounting clips. 

 

6.  In a cross pattern, (i.e. left, right, then up, down) tighten all four screws, by hand, until the 

speaker frame is snug against the ceiling.  Take care not to over-tighten as this may 
damage the mounting clips or the mounting frame.     

 

7.  Once all screws are tightened, the grill may be reinstalled on the front of the speaker.   

 

8.  The other end of the speaker wire is now ready for connection to the sound source
