Additional vertical shift of the Lens Holder

Introduction
The lens of the HDQ 2K40 can be shifted vertically. The maximum vertical shift range is ±110% in both directions, which is not
sufficient in some situations. To extend the vertical shift range in a certain direction, the Lens Holder can be shifted manually.
Extending the vertical shift range in a certain direction, will reduce the available range in the other direction.
