Proper maintenance ensures the longevity and optimal performance of your projector:

• Cleaning:
  • Lens: Gently wipe the lens with a soft, lint-free cloth designed for optical surfaces. Do not use abrasive cleaners.
  • Exterior: Clean the projector's exterior with a soft, dry cloth.
  • Air Filter: Regularly check and clean the air filter to prevent dust buildup, which can affect performance and cause overheating. Refer to the full manual for filter cleaning/replacement instructions.
• Cooling: Ensure the projector's ventilation vents are not blocked during operation. The cooling fan may produce audible noise, which is normal. Allow the projector to complete its cooling cycle after shutdown before moving or storing it.

6. Troubleshooting

If you encounter issues with your projector, refer to the following common problems and solutions:

• No Image or "No Signal" Message:
  • Verify all cables (power, HDMI, USB) are securely connected to both the projector and the source device.
  • Ensure the correct input source is selected on the projector.
  • Check if the source device (e.g., laptop) is outputting video to an external display.
• Image is Blurry or Out of Focus:
  • Adjust the focus ring on the projector lens.
  • Ensure the projector is at an appropriate distance from the screen for the desired image size.
• Image is Distorted (Trapezoid Shape):
  • The projector has automatic vertical keystone correction. If the distortion persists, manually adjust keystone settings via the projector menu.
  • Ensure the projector is placed as perpendicular to the screen as possible.
• Projector Overheating or Fan Noise:
  • Ensure ventilation vents are clear and not obstructed.
  • Operate the projector in a well-ventilated area.
  • Clean the air filter if it is dusty.
  • Excessive fan noise can occur if the projector is working hard or if the filter is clogged.
