The first components that should be solded are the 0603 resistor for their heights and dimensions. Then the user should sold the medium battery holder, then the lateral holder for the second battery. The final component is the PIC and the reed bulb (in lateral or vertical position). The last components are the wires for leds connection. After the complete mounting the user can put the batteries in the holders.


The battery holders must be oriented with the opening to the PCB edge (!), the PIC 1 pin is near to the first led anode connector. The two leds have the anode in the upper and mid pad of the J4 connector and the two cathods are shorted together in the bottom pad (see the assembly).
