JBL Wonderboom 3 Turn ON

We explain the JBL Wonderboom 3 Turn ON3 procedure here.  Now most speakers have a Power button that they prominently position on the unit so it’s easy to find.  Indeed, this speaker is no exception to this rule, since we find its Power button right on top, near the front, as we see next.

The Power button also has a light in it in the shape of a vertical line, that starts glowing when the speaker powers up. This lamp is dark when the speaker is OFF unless you are charging the speaker.  In that case, it glows red.

JBL Wonderboom 3 Turn ON: Step by Step

To power up this speaker, press the Power button. Then release after a quarter second or so.

Moreover, you needn’t hold it in for very long for the unit to see your press and then turn itself on.

When the JBL Wonderboom 3 comes on, the Power button glows, and the unit makes a distinctive sound to let you know that it is now running.

But if pressing the Power button does not start up the 3, it could be that the battery needs charging.  So if the unit won’t come on, try connecting a USB charger to it.  You can indeed run the 3 as it charges.

Now with a charger connected, the 3 should always power up when you click the Power button.  If it does not, then the unit may not be getting juice from your charger.  Check that the AC outlet for the adapter is live, that the adapter works, that the cable between it and the 3 is okay, and that the charger plug is fully seated in the USB port.

But if after all these checks the 3 still does not turn on, then the unit itself may be defective. In that case, just get a new one.
