Background
The Epson PowerLite S4 (V11H221020) was released in 2006 and advertised as a budget-friendly portable projector, geared toward K-12 education and small businesses alike. The PowerLite S4 features a lens cover and a single-foot design, transportation and on-the-fly height adjustments easier, as well as various color modes, and perhaps most important through K-12, security features to restrict use of the projector.
Identification
The PowerLite S4 is identifiable by its curved, silver plastic chassis, a large exhaust grate on its right side, and its single height-adjustment foot.
