After-sales Service Policy

1) Basic Terms

1.1 Proof of Purchase

Please keep your e-commerce order record, invoice, or receipt as proof for after-sales service and warranty claims.

1.2 Scope of Application

This policy applies only to products purchased via FJD-authorized online sales channels (official online store or authorized stores). For products bought from unauthorized third-party channels, FJD reserves the right to refuse warranty service. Please contact the original seller for after-sales support.

1.3 How to Request Service

• Submit a request through the e-commerce after-sales portal, customer service system, or the FJD official website.
• To accelerate diagnosis, provide an unboxing/fault demonstration video and a clear photo of the product serial number.
• After review, our support team will offer remote troubleshooting/repair advice or guide the next steps.
• If remote resolution is not possible, we will arrange a mail-in repair or authorized service-center repair.

1.4 Parts Replacement & Depot Repair

• When parts are replaced or the unit is sent back for repair, the removed original parts become FJD property for quality tracing.
• The repaired/replaced part or unit continues with the remaining original warranty (no extension).

1.5 Non-Official / Non-Authorized Products

For products not sold through authorized channels (including grey-market/non-official versions), FJD authorized centers may refuse free warranty service. Please contact your seller for solutions.

• For human-caused/out-of-warranty cases, the customer bears diagnostics, repair, parts, and shipping costs.

Labor fees are determined by service category, task complexity, required skill level, working hours, and travel time. A quote will be provided for your approval before any paid work begins.

• FJD reserves the right of final interpretation and to update this policy. Updates take effect upon announcement on our official channels.
