If you are experiencing an issue with your speaker, such as:

1. Not turning on
2. No sound coming out
3. Bluetooth not connecting

Begin by confirming that the power switch to the speaker is turned to the “on” position. The switch is located on the right side of the amplifier behind the seat, and if the control is on, you will see a colored LED illuminated from the switch and a blue LED emitting from the front and rear of your speaker. Once Power is verified, open your Bluetooth settings, look for the device labeled “Jie Rui BT-5908,” and connect. You may need to turn your Bluetooth setting on your device and the switch from the amplifier off/on to reset broadcasting. If the sound is still not coming from the speaker, inspect the cable connection on the back of the speaker.
