Today, we’re going to show you how to factory reset your speaker. There are two methods to factory reset this unit. The first involves accessing the menu from the lcd screen, and the second is a manual hard reset. The first method is a simple 5 step method. While your unit is powered on, click the main slash menu rotary button once to enter into the menu page as shown here. Next, turn the rotary clockwise to highlight “settings” then click the rotary button to select. Turn the rotary clockwise again to highlight “factory reset” and click the rotary button once more to select “go”. A warning window will pop up. Click the rotary button to continue. The LEDs on channels one through seven will then flash repeatedly for a few seconds until the entire unit powers off. The unit will then power on and the factory reset will be complete. The second way to factory reset your JBL PRX one is to simultaneously press and hold the main slash menu button and back button until the LEDs begin to flash on and off. The unit will power off, then back on and the factory reset will be complete.
