Using this Panasonic projector lens is easy. First, make sure your projector is turned off. Then, carefully attach the lens to the compatible projector models like PT - DW730, DX800 etc. Once attached, turn on the projector and adjust the focus if needed. When using, avoid exposing the lens to direct sunlight for a long time as it may damage the lens. For maintenance, use a soft, dry cloth to gently wipe the lens surface regularly to keep it clean. Don't use any harsh chemicals or abrasive materials as they can scratch the lens.
