Using a soldering iron, close both jumpers.

Using a hobby knife, cut both traces directly over the white dots.

Failing LEDs? Don’t fret, there is an easy way to fix it! The most

common cause of a failing LED is incorrect polarity. We have

designed a special trick into the Simon PCB. You can simply

cut the two traces and close two jumpers. This will swap the

polarity without having to remove the LED.
