The impressive 500:1 contrast ratio brings details vividly to life, and the attached 1-watt speaker dishes out clean sound. The projector is fully compatible with all PCs and Macintosh systems. The color-coded cables allow for instant setup, and nine onscreen languages offer international usability. Included in the box are all the tools you'll need for smooth presentations worldwide--a serial mouse, remote control with batteries and laser pointer, 2,000-hour lamp, a soft carrying bag and all the necessary cables. Proxima includes a full two-year warranty on parts and labor, and a 90-day/500-hour warranty on the lamp.
