Remove lens
It’s recommended to place the Lens caps of the original Lens packaging, back on both sides of the removed
Lens to protect the optics of the Lens.
It’s recommended to place the foam rubber of the original projector packaging, back in the Lens opening to
prevent intrusion of dust. Note that this foam rubber is packed in a plastic bag to prevent the dust, emitted by
the foam, from entering the projector.
5.5 Lens shift, zoom & focus
Motorized lens adjustment
The B-series projector is equipped with a motorized lens shift functionality and a motorized zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the DMD which result in a shifted image on the screen (Off-Axis). A 100% shift means that
the centre point of the projected image is shifted by half the screen size. In other words, the centre point of the projected image falls
together with the outline of the image in an On-Axis projection. Due to mechanical an optical limitations the shift range is limited as
well.
All DP2K lenses have a shift range of 50% up/down and 30% left/right. This range is valid for all throw ratios.
How to shift the lens of the B-series projector?
1. Use the up and down arrow keys on the local keypad to shift the lens vertically and use the left and right arrow keys on the
