The projector product is a product in the 3C catalog, that is, the product needs to obtain the 3C certificate and affix the 3C logo on the product before it is allowed to leave the factory, sell, import or use in other business activities. Therefore, when purchasing projector products, be sure to check whether the information on the 3C certificate is consistent with the purchased product information, including the manufacturer, manufacturer, product model, specifications and other information.
Projector products can apply for energy-saving certification. Products applying for energy-saving certification must first obtain 3C certification.
