How to use
Charge the speaker fully before first use using the supplied charging cable and a suitable power source. For wireless playback, enable Bluetooth on your source device and pair it with the speaker following the pairing instructions in the user manual. For wired use, connect an audio cable to the speaker’s input and the source device. Position the speaker on a stable, level surface and avoid submerging it in water; the IPX4 rating only protects against splashes. Monitor battery level indicators if available and recharge when playback time decreases significantly.
Usage recommendations
Place the speaker on a flat, elevated surface to improve sound dispersion and avoid placing it directly on soft materials that can muffle low frequencies. Keep the unit away from strong heat sources and ensure charging is performed in a dry environment. For consistent wireless performance, maintain a clear line of sight between the source device and the speaker within the Bluetooth range.
