2. Place the two ratchets, one on either side of the transducer knuckle, so
that the beads on each ratchet line up with the desired position number
on the knuckle (Figure 18a). If you are setting the ratchets at position 1,
the beads on each ratchet will line up with the rib on the transducer
knuckle to form one continuous line on the assembly (Figure 18b).
NOTE: The ratchets are keyed; make sure that the square teeth on each ratchet face
the square teeth on the transducer knuckle, and the triangular teeth face outward.
Hold the ratchets on the transducer knuckle with one hand and fit the
mounting bracket over them until it snaps into place with the other hand. Refer
to the illustration (Figure 18d).
