LED:Install red LED in D1.The LED is polarized, the long lead wire is positive. Look at the PC board for correct alignment.
LED:Insert flush to board.Solder and clip leads.
Transmitter
Kapi'olani Community College – KCCSTEM
Capacitors:Install capacitors C1, C3, & C4.The capacitors are polarized. The side with the white band is negative. The positive lead is longer. Look at the board for +/- signs. C1 fits inside the drawn circle.
Capacitors:Solder and clip leads.All of these capacitors are all 47 micro Farad.
Transmitter
