Step-by-Step Installation (continued) • As a minimum, the speaker must be secured using four screws provided on 2 parallel sides. See Diagrams 1 and 2, page 9 for reference. • If speaker is mounted against a crossbeam, install two additional #8 x 31/2" wood screws (not included) into side that is against crossbeam to secure speaker and prevent rattling. See Diagram 3, page 10 for reference. • Secure lock arms on sides that are not secured using wood screws. See Diagrams 1, 2 and 3, page 9 and 10 for reference. • The metal pivoting lock arms are pre-installed in the loudspeaker frame with Phillips screws. The lock arms can be rotated left or right by turning the screws. • Fit grille on speaker bezel. *VERY IMPORTANT* Please note that the pivoting lock arms are not designed to support the weight of the speaker. They are only designed to pull the speaker tight to the ceiling and prevent it from rattling. Do not use them for supporting the speaker. The screws going through the speaker and into the joists are there for support and must be properly used. 8
