terminal and pulling out the cable.

Keep the four nuts, four fl at washers, and
four locking washers in a safe place.

Carefully begin to remove the entire horn
assembly (with the high frequency driver
still attached). A fl at head screwdriver
may help in horn removal if it is sticking to
the cabinet.
Caution:
The horn weighs about 5
pounds, and the weight is not evenly
distributed.

Four nuts and eight washers may be
removed from the driver using the 10mm
open end wrench OR the 13/32 inch
socket. Turn counter-clockwise to loosen
and remove, clockwise to tighten. The
other pair is in the same place on the
other side of the horn assembly. Notice
that the fl at washer is on the bottom,
followed by the locking washer, and
fi nally the nut. Once they are removed,
the four headless screws need to be
liberated. Pliers may aid in the headless
screw liberation.
