Start with the label on the device
Look for a printed or attached label on the exterior of the unit. Check the base and rear without opening the housing. Use good light or a phone camera to enlarge small lettering.
MY135, MY139, YS35 and CN69 are useful starting points. If your label adds a letter, number or other suffix, include it. A shortened code, color or familiar shape is not enough to establish the exact version.
Keep these identifiers separate
Model
Copy the complete model exactly as printed, including punctuation and suffixes.
Lot or serial number
Record this separately if it appears on the label. Do not substitute it for the model code.
Order reference
Find this on the purchase record. It identifies the transaction rather than the device design.
Compare the device, box and guide
Place the three records side by side. Check whether the model text agrees and whether the pictured controls and connections match your unit. Keep both versions of any conflicting information instead of choosing the closest-looking one.
- One photo of the complete device.
- One sharp label photo, with every line visible.
- The model text on the box and the cover of the supplied guide.
If you are helping someone else
The purchaser and the person using the device may be different people. Say which role you have when asking for help; a name on a receipt does not establish who uses the device.
If the label is worn or missing, email support@mayluck.care with the photos and original retailer. Explain what you can read without guessing the missing characters.
