Manufacturer's warranty:
As a rule, this type of warranty applies to finished technical products. The presence of a manufacturer's warranty for the product is indicated on the receipt issued to you upon purchase (opposite the product there is a mark S/C). Usually, the kit includes a warranty card, which is filled out when purchasing the product. Sometimes, product maintenance is carried out not according to warranty cards, but according to serial numbers. In this case, you will not find a warranty card in the kit, but the user manual will indicate a list of service centers that provide warranty service for this product.
