Throw distance
For screen sizes between 40” and 500” not indicated on the above table, use formulas below.
Projection Distance = Screen Width (H) x Lens Magnification
Throw distance for GT10RL lens (m/feet) =H x 1.0 (For H between 0.8 m/2.7feet and 6.1 m/20.0 feet)
Throw distance for GT13ZL lens (m/feet) =H x 1.3 through H x 1.6 (For H between 1.1 m/3.5 feet and 9.8 m/32.0 feet)
Throw distance for GT19ZL lens (m/feet) =H x 1.8 through H x 2.4 (For H between 1.5 m/4.8 feet and 14.6 m/48.0 feet)
Throw distance for GT34ZL lens (m/feet) =H x 3.4 through H x 5.2 (For H between 5.5 m/18.1 feet and 52.8 m/173.2 feet)
NOTE: Distances may vary +/-5%.
1. Determine the image size
2. Set up a screen or select a non-glossy white wall onto which you
can project your image.
3. Install the optional lens to the projector.
4. Connect the supplied power cable.
5. Set up the projector.
6. Connect a PC, VCR, DVD player, or other equipment.
7. Make settings or adjustments on the projector.
