Step 5 Solder the microphone onto the board

Now you will solder the microphone onto the board. You want to generally try and shove the pins of the microphone through the board holes here - and use solder to make it stick there. Then take some speaker wire and solder it onto the connectors on the board (if you took it apart before you know where they will go now). Then wire the speaker wire through the phone, removing the speaker-end of the handset, take out the old wires that were there, and attach our new wires onto it.
