  • Page 3: Read This First

    Read this first! Always follow these precautions WARNING: Do not look at or place your skin into the light emitted from the lens while the projector is being used. Doing so can cause burns or loss of sight. z Strong light is emitted from the projector’s lens. Do not look at or place your hands directly into this light.
  • Page 4 Read this first! (continued) r Hazard distance (IEC/EN 62471-5:2015) The distance from the projection lens surface, at which the emission reaches the Accessible Emission Limit (AEL) of risk group 2, is known as the hazard distance (HD) or safety distance. The area where the emission exceeds the Accessible Emission Limit of risk group 2 is called the hazard zone (HZ).
  • Page 5 The projectors compatible with each projection lens may be added or changed without notice. For the latest information, refer to the following website. https://docs.connect.panasonic.com/projector Attention z If the light projected from the projector directly enters the eyes while you are inside the hazard zone, the retinas may be damaged.
