• PROJECTION LENS
Available in three versions:
• Standard throw range (1.94:1 to 2.40:1);
• Short throw range (1.64:1 to 1.86:1); and
• Long throw range (2.52:1 to 4.00:1; D-73d Ultra only).
• HORIZONTAL AND VERTICAL LENS SHIFT CONTROLS
To access the lens shift controls, insert the included 5.0-mm Hex wrench into the
opening and turn it as needed to shift the lens in the desired direction (refer to
Adjusting the Focus, Zoom and Position of the Primary Lenses on page 55).
• LENS LOCK (Standard or Short-throw Lens)
The screw to the right of the lens activates the lens lock, which freezes the zoom and
lens shift settings to keep the projector images aligned over time.
When shipped from Runco, the lenses are unlocked. To lock them, use the same
5.0-mm Hex wrench (provided) that you use for lens shift adjustments. (Turn
clockwise two or three turns.)
