| - | The order in which you populate the components on the PCB is not critical. We usually start with the RJ11 socket. The socket is a tight fit. Be sure that all six pins align with the holes in the PCB before applying too much pressure. Then fit the zenner diode, D6, directly behind the RJ11 socket. Observe polarity - the bar on the component should match the bar on the PCB legend. Now, fit R6 (1K5 ohm), just to the side of the RJ11 socket. | + | The order in which you populate the components on the PCB is not critical. We usually start with the RJ11 socket.
