LEDs (indicator lights): Insert the four LEDs into the front of the
board. Each LED has a short leg and a long leg. The short leg
goes into the hole labeled " ." Also make sure it sits flush with
the PCB. Then solder into place.
Battery Clips
(hold batteries): Insert battery clips, make sure
clips point toward each other so the battery fits. Ensure clips
are flat against the board. Then solder from the bottom of board.
Slide Switches (sound and power): Looking at the top of the board,
insert switches. Keep the iron tip away! Plastic melts easily. Flip
the board over, then begin to solder.
