7. Place the wall mount assembly against the wall, aligning
the plate holes with those drilled, and secure with
appropriate hardware (see figure 5), using a powered
screwdriver with an appropriate screw bit.
8 . When the assembly is securely in place, loosen the hex
cap screw (turn counter-clockwise) and rotate the front
section back into a vertical position with the hex cap screw
at the top. Using the allen hex tool, turn the hex cap screw
clockwise to tighten.
9 . Repeat steps 1 through 8 for the second assembly mount.
Preparing the speaker for mounting
1 . Remove the cover from the back of a speaker by pulling
the two attached tape tabs towards you and lifting the
cover away.
N If the tape has been removed previously, carefully insert
a flat bladed screwdriver to loosen the two lower locking
tabs first, then one or more of the top tabs. Take care not
to crack or chip the cover, or break off the locking tabs.
Lift away the cover as it comes free.

2 . At this point connect an optional seismic safety cable (not
supplied) to the rear of the speaker by looping it through
the hole on the box bracket and securing (see figure 10).
Anchor the other end to a suitable secure point above the
speaker wall assembly mount.
C
The safety cable should be of sufficient strength
to support the full weight of the speaker and wall
mount assembly combined.
N
Ensure that the cable is long enough to allow you to
connect the speaker wires and to manipulate the speaker
into position on the assembly mount.
