JBL Charge 5 Service Mode

When the JBL Charge 5 is in Service Mode, the buttons do not work. So, assuming that all the systems are okay, we’ cover how to end Service Mode, and restore proper function.

JBL Charge 5 Service Mode: May Be Active

First, when in this (often called ‘weird’ or ‘secret’) mode, the Charge 5 does not power ON without the charger. Thus, it will not run on the internal battery while in Service Mode.  Furthermore, when you do apply outside power, it powers up without you even pressing the Power button.  So it comes ON as soon as you connect the charger.

Further, you cannot turn off the Charge 5 while in this mode. Not without the charger. And then, when you disconnect the charger, the speaker powers off without pressing the Power button.  So when this Service Mode is active, the Power button appears to not work.

Indeed, none of the buttons seem to work, except for the ones you need to exit Service Mode.  E.g. The Charge 5 won’t pair with any devices.

JBL Charge 5 Service Mode: How to Turn ON

This is what you may have done by accident prior to your speaker freezing… To turn on this mode, power up the speaker first. Then press the Bluetooth and Play-Pause buttons together. Hold them in until the speaker powers OFF. So this usually takes ten seconds or so.

Note that you can enter this mode whenever the 5 is ON. It doesn’t matter whether the charger is present or not. You can also enter it whether the 5 is running on batteries or external power.

How to Exit Service Mode

Now you can restore proper operation by deactivating this mode. But note that when Service Mode is ON, then you must connect the charger to turn it OFF. Why?  Because the JBL Charge 5 won’t come on without outside power. Yet you can’t change modes without powering it up first.  So, you need a USB-C power adapter to make this fix.

1. 1. So, connect your speaker to external power. Next, the speaker comes on.
   2. Then, with the speaker Power button glowing, press the Bluetooth and Play-Pause button combo. Then hold for ten seconds or so, until the Charge 5 powers off.
   3. Finally, normal operation returns the next time you power it on. So Service Mode is over.

Finally, all buttons should now work again, whether or not you connect the AC adapter.
