Remote guidance for repairs (via documents, photos, and videos)

After-sales staff at an Italian online retailer with no professional repair background.

M***o, an online wheelchair seller based in Milan, faced a problem: a customer reported that their wheelchair wouldn't start. There were no local repair centers, and shipping the unit back for service was too expensive. The Baichen team immediately created annotated photos of the circuit diagram and a 3-minute video tutorial, guiding M***o’s staff step-by-step on how to check the fuse and controller plugs. The issue was easily resolved. M***o commented, "You are more professional than many local repair shops."
