TIP:
• Brightness normally decreases with use, but by selecting [CONSTANT BRIGHTNESS] mode, sensors inside the projector detect
brightness and automatically adjust the output, thereby maintaining a constant brightness throughout the life of the light module.
However, if output is already at its maximum, brightness will decrease with use.
