Warranty card is the basic certificate of maintenance, and maintenance needs to issue both warranty card and invoice to enjoy warranty service.

Only articles imported or produced from normal channels have warranty cards. The warranty card will generally indicate the model and serial number (the serial number of the fuselage and the warranty card should be one-to-one, and the serial number of the digital camera can be inquired by telephone), as well as the purchase time and warranty time, warranty point and telephone number, and the most important thing is to have the signature or seal of the manufacturer.
