Wireless Dongle Lamp Wireless Standard: IEEE802.11b/g/n Wireless: One WiFi USB (type A) connector for supporting wireless dongle (Embedded WiFi, USB interface, S500 is optional). OS environment: Windows 7/Vista/XP/2000, MAC OS X Support: Presentation slides and projector control. Allow connection up to 30 users at the same time. 4-to-1 split screen. Allow four presentation slides to be projected on screen. Conference Control mode. Supports Audio Projection (need to install extra driver) Philips 280 W user-replaceable lamp (up to 3000 hours in eco mode) NOTE: The lamp life rating for any projector is a measure of brightness degradation only, and is not a specification for the time it takes a lamp to fail and cease light output. Lamp life is defined as the time it takes for more than 50 percent of a lamp sample population to have brightness decrease by approximately 50 percent of the rated lumens for the specified lamp. The lamp life rating is not guaranteed in any way. The actual operating life span of a projector lamp will vary according to operating conditions and usage patterns. Usage of a projector in stressful conditions which may include dusty environments, under high temperatures, many hours per day, and abrupt powering-off will most likely result in a lamp's shortened operating life span or possible lamp failure.
