How to use
Place the projector at the appropriate short-throw distance from the screen according to the throw ratio (0.69–0.83) and adjust zoom and vertical keystone (±40°) to obtain a correctly framed image. Connect a source device via HDMI, VGA or USB and select the input on the projector. Use the remote control or onboard menus to set brightness mode, aspect ratio and resolution. For longer lamp life, select Eco or SmartEco modes when high brightness is not required.
Usage recommendations
For best image quality, use a flat, neutral-colour projection surface and position the projector so the lens is perpendicular to the screen. Choose Eco or SmartEco modes for extended lamp life and lower fan noise in darker viewing environments. Ensure adequate ventilation and operate between 0–40 °C.
