All measurements are approximate and may vary from the actual sizes. If you want a permanent installation
of the projector, we recommend that you use the actual projector to physically test the projection size,
distance, and the projector's optical characteristics prior to the installation. This helps you determine the
exact mounting position which best suits your installation.
