Using this frame is easy. First, make sure your L500 Plus touchscreen is turned off. Then, carefully place the frame around the touchscreen, ensuring it aligns perfectly with the edges. When handling, avoid using sharp objects that could scratch the frame or the touchscreen. For maintenance, use a soft, dry cloth to clean the frame regularly. If there are stubborn stains, you can dampen the cloth slightly with water. Keep the frame in a dry and clean environment to prevent any damage.
