the opposite position (outer edge of the disc).
Tighten the centering screws (9.3; 9.5) until the
components are roughly in the center of the
holes.
The lettering (e.g. DF, PH 1. . . ,

upwards,
the whole- and quarter-wave
compensators (9.6) must be inserted with the
correct orientation: the notch must point
towards the centre of the disc! The lettering of
