8. Troubleshooting

• Direct Charging: If using direct Micro USB charging, ensure the cable and power source are functional.

8.3. Bluetooth Pairing Issues

• Pairing Mode: Ensure the speaker is in Bluetooth pairing mode (BT indicator light flashing).
• Device Proximity: Keep your Bluetooth device within close range of the speaker during pairing.
