Troubleshooting Questions and Answers:

A1: Firstly, ensure that the Bluetooth on your smartphone is enabled. Then, make sure that the Jieli Br 21 Driver is in pairing mode by pressing and holding the power button for 5 seconds until the LED indicator flashes rapidly. If the issue persists, try restarting both devices and attempt the pairing process again.

Q2: My Jieli Br 21 Driver is not producing any sound. What could be the problem?
A2: First, verify that the volume on your Jieli Br 21 Driver is not set to the minimum by pressing the volume up button. Additionally, check if the audio source (e.g., smartphone, computer) is also properly connected and its volume is turned up. If none of these seem to be the issue, try performing a factory reset by pressing and holding the power button for 10 seconds.

Q3: The battery of my Jieli Br 21 Driver drains quickly, even after a full charge. How can I resolve this?
A3: If you notice fast battery drainage, it is recommended to fully discharge the battery of the device and then recharge it to its full capacity. Additionally, ensure that the Jieli Br 21 Driver is not continuously connected to multiple devices at the same time, as this may cause excessive power usage. If the problem persists, consider replacing the battery with a new lithium-ion battery of the same specifications.
