7. Place the wall mount assembly against the wall, aligning
the plate mounting holes with those drilled, and secure the
assembly with appropriate hardware (see figure 5) using a
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 hex tool, turn the hex cap screw clockwise
to tighten it.
9 . Repeat steps 1 through 8 for the second assembly mount.
Preparing the speaker for mounting
1 . If the back covers were installed previously, remove them
by carefully inserting 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 it (see figure 9).
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.
Seismic Safety Cable
Anchor this end to a
suitable secure point.
Attach cable
here and
secure it.
