Mounting Instructions:

1. Insert the PCBA into the slots. Preferably, only mount the XLR insert on the PCBA and no other components. Other parts may get in the way when soldering the pogo pin or get damaged during handling.
2. Tighten the two bolts. Do not over-tighten!
3. Insert the PTFE tube until it hits the PCB edge. Place the protruding roll of PTFE tube on a block of wood and cut it to length with a sharp knife.
4. Insert the pogo pin. Leave the short, spring-loaded pin sticking out about 10 mm. Do not solder yet!
5. Remove the capsule and the original PCBA from the microphone body. Transplant the metal tailpiece of the PCBA from the original PCBA to your DIY PCBA.
6. Insert the PCBA into the microphone body and tighten one screw of the tailpiece to hold the PCBA in place. Pull or insert the pogo pin until the tip is level with the top edge of the microphone body.
7. Remove the PCBA from the microphone body. The pogo pin will probably extend past the edge of the solder pad. Mark the edge of the solder pad on the pogo pin with a marker. Remove the pogo pin and cut it to length.
8. Repeat step 6, now with the shortened pogo pin. Remove the PCBA and solder the pogo pin to the PCBA. Be careful not to melt the nose cone plastic.
9. Your PCBA is now ready to solder the other parts.
