Installation
Install Ceiling Mount Adapters/Projector Stands: For ceiling installations, these
brackets bring the mounting points for the projector mounting rails (included with the
projector ceiling mount kit) from the bottom of the projector up and around the AutoScope
lens motor housing. For floor installations (where the projector is upright), the adapters
allow the projector to lie flat on the mounting surface.
Using the four (4), supplied M6 x 12mm Flat-Head Phillips screws (item #6), attach the
AutoScope Ceiling Mount Adapters/Projector Stands (items #4 and #5) to the projector as
shown in Figure 3-6.
