1) Charge the CASE first for 30 minutes (case Dot LED = orange steady while charging, white steady when full). A dead case cannot power the buds. On the Pro, the guide light breathes white while charging and is constant white when full.

2) Put both buds in the case, close the lid, and charge for 30 minutes (buds: orange LED steady; LED off when full).

3) Use the provided C-type cable to a known-good adapter or a laptop / PC USB port (PC ON, not asleep); try a different USB port / wall socket if needed.

4) Clean the bud and case charging contacts with a dry cloth – dirty pins are a common cause of 'not charging → dead'.

5) Avoid high-power chargers (over 2A) and confirm the wall socket works.

6) If after 30 minutes there is still no LED, no voice prompt and no charging indication, it is likely dead. Before concluding check for any Physical damage on the product.

Note: Buds auto power-ON when the case lid is opened with buds inside; they auto power-OFF below 3.1 V or after 10 minutes with no connection. A 'dead' complaint is very often a fully drained bud or a dead case – always confirm charging first.

• In case the device is confirmed dead / faulty – arrange the RPU (Replacement Pick-Up). Please ensure the issue is reproduced before arranging the RPU.
