Practical answer: Use this guide as a purchasing checklist, then confirm model-specific functions, accessories, packing, documents and support in the signed quotation.

1. Separate the main unit from accessories

Machine bodies, screens, power systems, handles and consumable parts may have different warranty conditions. BY BEAUTY’s standard policy is one year for the main unit and three months for accessories, subject to the confirmed quotation.

2. Confirm what evidence is needed

Remote diagnosis usually requires the model, order reference, a clear description, photos, a short video and any screen message. Preparing this evidence helps the technical team isolate the issue.

3. Ask how training is delivered

Training should cover setup, operating sequence, routine care, interface use and basic troubleshooting. Confirm whether manuals, product videos or live video guidance are available.

4. Understand parts and shipping responsibility

If a replacement part is approved, confirm who provides it, who pays the freight and what installation support is available.

5. Keep configuration and customer records

Keep the quotation, packing list, voltage, plug, handle list, software language and delivery date connected to each customer record.

6. Evaluate response quality before ordering

A useful response should request evidence, explain the next diagnostic step and avoid unsupported promises.
