According to the content of the service, it can be divided into three methods: fault handling, regular service, and network remote service. If a malfunction occurs during the warranty period of the system, corresponding services will be provided according to the classification. Firstly, the issue will be resolved through hotline telephone. If the issue cannot be resolved through telephone, our engineers will arrive at the user's site within 12 hours. First level malfunctions will be repaired within 4 hours, and second level malfunctions will be repaired within 2 hours. Our company will bear the expenses during this period.

The classification of fault levels is as follows: First level fault: Due to the serious impact of the fault on system operation
Secondary fault: The system still operates despite the impact of the fault on its efficiency
Customer service hotline 24-hour after-sales service: 021-57489979.

The handling method for faults and damages caused by human factors during the system warranty period is the same as the first method mentioned above, but the cost of replacing parts during this period shall be borne by the buyer.

After the warranty period expires, our company still has the responsibility and obligation to provide technical services to the buyer, and spare parts will be provided based on the itemized price list of alternative spare parts. The equipment is maintained for life and regularly visited by users to provide tracking services.
