About the after-sale service for Kvtester testers

      1:  Upgrade of product software system: Our products support U disk upgrade. We only need to send the updated program to each other. The other side can upgrade through U disk and show the upgraded video to customers.

      2: Replacement of product hardware: Our products adopt modular structure design, which includes several circuit board modules with independent functions. At the same time, our products have the function of fault code output and self-inspection. We can judge which circuit board module is faulty when customers provide us with error code or self-inspection photos or videos. After providing brand new PCB modules and special tools, customers can complete the replacement of PCB in the field. Can provide customers with failure code demonstration video and equipment internal photos.
