Rotary Knob Installation Procedure
1) Using a new rotary knob, insert the metal tension plate (removed in
above) into the centre of
the knob, aligning the plate correctly with the notches on each side of the hole. The plate, which is
slightly curved (to provide tension), should be positioned with the curved surface facing towards the
center of the hole, as shown in
Figure 8-29 Tension Plate Fitted in Centre of Knob
2) Carefully place the new rotary knob into position on the securing pin, taking care that the tension
plate remains in position inside the knob, while aligning the core of the knob base with the flat-sided
notch on the securing pin - see
NOTE:
The notch must be aligned correctly, otherwise the rotary knob will not sit at the correct height on the
external keyboard.
3.) Gently push the rotary knob down until it snaps into position.
