Tips:
When the projector detects shaking or rapid movement, it will automatically
initiate autofocus adjustment and keystone correction to ensure optimal image
quality. If you encounter unclear images or an imperfectly squared display, please
use the remote control's focus button for manual adjustment or utilize the four-
point keystone correction to manually correct the image shape.
