Altering the HF horn dispersion

Fig. 11: Horn dispersion label

The Qi7 HF horn has a square flange allowing it to rotate through 90°.

Tools required: 3 mm Allen key (Torque wrench)

To rotate the horn the front grill needs to be removed.

1.

Undo the six countersunk Allen screws that hold the front grill
in place and remove the front grill.

2.

Undo the four countersunk Allen screws of the horn.

3.

Rotate the horn through 90° - Fig. 11.

4.

Refit the horn and tighten the four screws of the horn to a
torque of  2 Nm.

5.

Refit the front grill and tighten the six screws to a torque of
2 Nm.
