After using the projector, the lens and body will accumulate dust and dirt. Therefore, regular cleaning of the projector is the key to maintenance and care. Use a dedicated cleaning cloth and cleaner, and avoid using cleaners containing chemicals that can damage the projector. 2. Regularly Replace Filters The filter of the projector is used to prevent dust and other debris from entering the interior of the projector. As the use time increases, the filter will accumulate dust, affecting the projection effect. Therefore, it is necessary to replace the filter regularly. 3. Maintain Good Ventilation The projector generates heat during operation, so it needs to have a good ventilation environment. Avoid placing the projector in a closed space or near other heat sources to avoid affecting the cooling effect. II. Regular Maintenance and Care 1. Regularly Check the Bulb The bulb of the projector is a vulnerable part that needs regular inspection. If you notice that the bulb brightness decreases or flickers, it should be replaced promptly. 2. Deep Cleaning of the Projector In addition to daily cleaning, deep cleaning is also necessary. You can send the projector to a professional maintenance center for deep cleaning and care to ensure the performance and lifespan of the projector. 3. Regularly Calibrate the Projector The color and brightness of the projector will change with increased use time. Therefore, regular calibration of the projector is necessary. You can use professional calibration software or tools to ensure the best projection effect. III. Notes for Prolonging Service Life 1. Avoid Frequent Switching On and Off Frequent switching on and off can damage the bulb and circuit of the projector, so it should be avoided as much as possible. If the projector is not used for a long time, it should be turned off and the power plug should be pulled out. 2. Avoid Vibration and Impact The projector should be placed on a stable surface and avoid being shaken or collided with to prevent loose or damaged internal parts of the projector, affecting its performance and lifespan. 3. Use Official Accessories and Consumables Using non-official accessories and consumables may damage the projector, so it is recommended to use official accessories and consumables to ensure the performance and lifespan of the projector.
