Maintenance
To ensure the longevity and optimal performance of your KEJOG Mini Projector, follow these maintenance guidelines:
- Ventilation: Always ensure proper airflow around the projector. Do not block the ventilation openings. Operating in a well-ventilated area helps dissipate heat and prevents internal component damage.
- Cleaning: Use a soft, dry cloth to clean the exterior of the projector. For the lens, use a specialized lens cleaning cloth and solution to avoid scratches. Do not use abrasive cleaners or solvents.
- Storage: When not in use for extended periods, store the projector in a cool, dry place, away from direct sunlight and extreme temperatures.
- Dust Protection: Keep the lens cap on when the projector is not in use to protect the lens from dust and scratches.
