Assembly Step 15: LED Indicator
Remove the frontpanel again. Take the LED (light emitting diode) and bend its legs by 90 degrees as shown in the picture. Fit it into the board. Make sure the short leg of the LED goes into the side where the silkscreen circle has its notch (flattened side). The diode body also has a notch at the same side.
 
 
Now put on the frontpanel – the LED must go through the center hole. Put on the nuts again and tighten them down with a wrench. Be careful not to over-tighten them, damaging the connectors threads!
 

The frontpanel now holds the LED securely in place. Turn the board around and solder the LED’s legs onto the board.
