Maintenance Implementation

We will arrange for repair personnel to repair the product within the repair cycle and return it to the customer. The repair cycle is defined as the total number of working days from the day the factory receives the returned product to the day it is repaired and sent back to the customer. During the repair process of high-risk products, business personnel will contact the customer to confirm relevant information. If the response to the information is delayed due to the customer's reasons, the repair cycle will need to be extended accordingly.

Repair completed

After the product is repaired, we will conduct a comprehensive test on it. Once the test is passed, the repair team will properly package the product and return it to the customer.
