1) Place BOTH buds back in the case, close the lid ~10 seconds, then open it – both buds should auto power-on and re-team (TWS reconnect).

2) Force pairing from the case: buds in case, lid open, long-press the case button 10 seconds until the white LED flashes three times.

3) On the phone, 'Forget' the 'ALT BUDS / ALT BUDS(S)' entry, then pair fresh – the phone should connect to a single stereo device, not one bud.

4) If one bud shows no voice prompt and does not charge after 30 minutes, that bud is likely faulty.

Note: The L/R buds pair with each other (TWS pairing) before connecting to the phone. If only one appears, the TWS link has broken or the bud's battery is drained.

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