I bought a charge 4 Bluetooth speaker and won't fully charge.

Try doing default factory settings.
Step 1. Press the "Power" button located on the top center part of your JBL Charge 4 Bluetooth speaker. The speaker will be powered on when the LED backlight under the Power button is lit.
Step 2. Hold down the "Bluetooth" and "Volume Up" buttons at the same time for roughly three seconds. The Volume Up button looks like a plus sign. Additionally, it's important to hold down the "Bluetooth" button in the center of the device next to the Power button, as it's easier to hold down. After three seconds, the LED ring around the Power and Bluetooth buttons will briefly light up before the JBL Charge 4 powers down.
Step 3. Press the "Power" button again to turn the JBL Charge 4 Bluetooth speaker back on. The Charge 4 will instantly turn on in Discovery mode, with the Bluetooth LED blinking on and off, and the speaker making a pinging sound. This confirms that you've successfully reset your JBL Charge 4 to its default factory settings. You'll need to pair or re-pair any devices you want to play audio through the JBL Charge 4 speakers with the device.

What does the manual tell us. Here is a link to try. If my memory is correct the RED LED turns off when it is charged about 4 hours.

Dear Anonymous,

• Make sure Bluetooth is enable on all the devices your want to use.

• Remove this device and any other devices that are not currently in use. (I am assuming you are using a cellphone or tablet)

• You can either put both devices in "Discovery Mode" let them see each other and Pair them again. Or

• If they already "see" one another .Re-Pair them.

• If they do not generate their own code, try enter "0000" and

Pair

• As far as the device that randomly stop playing, it might the battery is being overcharged. Put it On let, it play or in use until the battery has run out of juice; then charge it fully and see what happens. If the battery charge too quickly, you might need another one or take it in for service. In case of the Auvio speaker, take it back to Radio Shack if that is where you bought it.

Best of Luck,
JP

Make sure that the unit is fully charged by a micro USB the light on it will be red until it's fully charged put phone in search mode and press the center button until the light flashes red and blue after the phone finds it you should have an option to auto pair when it's not in use it will turn off when paired and working pressing either track button will start the music player then just play with the buttons and see what it does you can stop anything from the phone controls

It won't charge

This speaker doesn't include charging capability.

As soon as you connect the headset the sound should come through them.

Is your headset bluetooth enabled? If so, then you have to register the headset with the phone ie get the phone to do a search for Bluetooth enabled devices and it should find the headset.

Make sure the headset is fully charged if it is Bluetooth enabled also.

Hope this helps?
