With a native XGA resolution (1024x768) and 4500 ANSI lumens of brightness, it delivers readable images on larger screens and under ambient light. The projector uses a lamp light source with a rated lifespan of 6000 hours in normal use and up to 10,000 hours in economy mode. It supports multiple installation orientations including front, rear and ceiling projection, and accepts computer graphics up to 1920 x 1200 for flexible source compatibility. The unit is finished in black and weighs approximately 2.8 kg, making it portable enough for occasional relocation.

Advantages

The DLP projection technology provides good color contrast and image sharpness suitable for text, charts and video. High brightness helps maintain image visibility in rooms with ambient light. Long lamp life in economy mode reduces maintenance frequency and operating cost. Multiple projection modes and broad graphics resolution support increase installation flexibility for different venues and sources. The projector's compact form factor and moderate weight simplify transport and temporary setups.

How to use

Install the projector on a stable surface or mount it on the ceiling according to the chosen projection mode, ensuring correct distance and alignment to the screen for optimal image size and focus. Connect a computer or video source using the appropriate input ports and select the matching input on the projector. Adjust focus, keystone correction and image position as required. For prolonged use, consider switching to economy mode to extend lamp life and reduce fan noise. Follow the manufacturer's safety and ventilation guidelines and allow the lamp to cool before moving the unit after operation.

Recommendations

Operate the projector in a well-ventilated environment and clean intake/exhaust vents regularly to maintain cooling efficiency. For consistent image quality, perform lamp replacement and optical maintenance per the service interval recommendations and use genuine replacement lamps. When projecting in rooms with ambient light, increase projector brightness settings or use a high-gain screen to improve contrast.
