Depending on your particular configuration your nVision
may physically look different than the model shown, and all
descriptions are intended for general representation only. Some
settings can be enabled and disabled using the
Crystal Control
software, and may not be visible on your model. For an in-depth
look at all functionality and options for the nVision, please refer to
the nVision Operation Manual located on your nVision CD
(also available at www.crystalengineering.net/downloads).
