NOTE
With the introduction of the G1315B/G1365B DAD/MWD the appearance of the z-plane
(front metal plane) has been changed (no holes any more) and an isolation seal between
the optical unit and the z-plane. Therefore, some of the figures may still show the old
appearance of the G1315A/G1365A. For G1315A/G1365A detectors refer to “Removing the
Optical Unit (G1315A/G1365A)” on page 154.
