The following steps require the use of a soldering iron. In the following steps, disconnect the 
wires at the PCB end only, after unsoldering, bend wires away from PCB to avoid burning the 
wire insulation with soldering iron. Avoid sharp bends to prevent breaking wire. (If wires appear to 
be brittle, it is highly recommended that they be replaced with pre-tinned #20-#22AWG stranded 
wire).
