发明名称 AUTOMATED WARRANTY REGISTRATION
摘要 A method for determining when a wireless communications device's warranty period begins uses the wireless communications device's first use date as a proxy for the start of the warranty period. After being powered-on, the wireless communications device checks a non-volatile warranty registration status-flag. If that flag indicates that the wireless communications device has not previously registered, the wireless communications device sends a unique identifier, such as a serial number, to a warranty registration center. The warranty registration center stores the identifier with an associated registration date stamp. The wireless communications device then changes the warranty registration status flag to indicate that the device has been registered for warranty purposes. Once this automated warranty registration is complete, the wireless communications device proceeds with normal operation. The recorded first use date may be used as the start of the warranty period.
