| Step 8 Insert the four PN2222 Transistors. Spread the legs apart and insert it so that the flat side is facing down to give the appearance of a bell when looking at the top. Put it in the board so that the distance from the bottom of the transistor to the board is about half the height of the transistor case. Be careful not to push it all the way to the board as you might break the legs. Turn the board over and tack solder one leg on each transistor, check to make sure that they all look straight and then solder the other legs and then trim. |

| Step 7 Insert the switch. Note the orientation of the switch with the pin on one side pointing to the left as you look at the front of the tree. Be careful when inserting the switch to press on the edges and not on the button itself as you can break it. |

| Step 6Insert the IC socket, paying attention to the orientation of the dip on the side of the socket and making sure it matches the board. Carefully turn the board over and solder one tab at the corner of the socket. Turn the board over to make sure it is flat against the board before turning oit over and soldering the remaining pins. |
