process,and truly realize the function of charging and discharging.

Solve the pain point that some products can not be used during the

charging process.

When powered by USB alone: The red light flashes,indicating that the

power supply is normal.

When powered by a separate battery: The yellow light is always on,

indicating that the battery power supply is normal; the yellow light

flashes, indicating that the battery is low.

When the USB and battery are connected at the same time:The red

light flashes to indicate that the battery is charging; the red light

always indicates that the battery is fully charged.

(Note that if the USB input is suddenly disconnected during the

charging and discharging process, there will be a few seconds of

interruption due to the charge and discharge mode switching at this

time,after which Bluetooth will automatically restart,automatically

connect and maintain the previous playback state)

Bluetooth settings.If the phone calls, you can answer or hang up the

phone through the PLAY/STOP button. You can choose to send from

microphone.
