This JBL Charge 5 reset Bluetooth routine explains how to restore default settings. In short, it goes as follows: First, power on the speaker. Next, press the reset Bluetooth button combo code (given below). Wait for the unit to power OFF, and once that occurs, Bluetooth reset is complete. Now for an in-depth look at this process, see below.
JBL Charge 5 Reset Bluetooth: Step by Step Routine
Moreover, Bluetooth resetting the speaker clears out any earlier paired Bluetooth devices from memory. Plus, it stops the unit from pairing to any nearby Bluetooth devices after reset. Also, do this it to get the Charge 5 ready for sale or re gifting.
1. Turn on the Speaker
Press and release the Power button. It should instantly light up solid white.
Find the Power button, pointed at by the green arrow in the last picture above.
Then, the Power button lights up, as shown next. In our case, since we’ve paired the speaker with Bluetooth devices before this, it does not enter Bluetooth pairing mode. We can tell that because the Bluetooth button remains OFF, rather than blinking white. Note the dark Bluetooth button, to the right of the glowing Power button in the next picture.
2. Wait for the Power ON Sound
The Charge 5 makes a rising electric guitar strum sound when it powers up, and is ready for use.
3. Press the Volume UP and Play-Pause Buttons Together
See the next picture to find the Play-Pause and UP Volume buttons.
The Charge 5 soon enters reset Bluetooth mode. Note that both the Power and Bluetooth buttons and the oval shaped ring that surrounds them. All of these light up for a brief period during reset. I.e. The ring and both buttons glow gray-white.
Then after a short pause, the JBL Charge 5 turns off. All lights go off, and it makes the power-down guitar sound.
The next picture shows the speaker, powered down. All buttons are dark.
4. Check that your JBL Charge 5 Did Indeed Reset Bluetooth
Next, power on the speaker again, as discussed in the first step above. In short, press and release the Power button.
Now this time, after reset, our speaker instantly comes up in Bluetooth discovery mode, as shown next. We did not have to press the Bluetooth button first. Note that the Bluetooth button blinks to let you know that the speaker has entered Bluetooth pairing / discovery mode. When this button blinks or is dark, the speaker is not in a pairing session. Indeed, we expect it not to pair to anything after a reset.
5. Done with JBL Charge 5 Reset Bluetooth !
The reset Bluetooth is now complete. Thus you may now pack it up for sale, or pair it again with your favorite Bluetooth devices.
Now as noted prior, the speaker afterwards no longer auto pairs with any device. So you need to forget the previously paired Charge 5 in the Bluetooth devices section of your source device. Then you manually pair the Charge 5 with that device again if you wish. Finally, after that, any time that both speaker and that device are in range, auto pairing happens once more.
