High Frequency Driver replacement continued:

5

The positive (solid blue) and negative

(blue and black) cables are still

attached to the high frequency driver

terminals. Remove the cables from their

terminals simply by pushing down on the

terminal and pulling out the cable.

7

Keep the four nuts, four ﬂ at washers, and

four locking washers in a safe place.

4

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.

6

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.
