  1. Remove the XLR connector by turning the XLR setscrew counterclockwise.
  2. Unsolder the BLUE and RED lead wires from pins 2 and 3 of the XLR connector.
  3. Unscrew and remove the screen and grille assembly.
  4. Remove the cartridge retaining ring using a set of snap-ring pliers. Insert the pliers into the holes on the ring. Close the pliers so that the ring compresses slightly, then remove the ring.
  5. Remove the old cartridge and attached leads.
  6. Run the leads from the new cartridge through the handle so they come out on the XLR end.
  7. Insert the new cartridge in the case, making sure it is properly seated in the notches provided. Also make sure that the wire leads are aligned with the nameplate and that they are not pinched between the cartridge and case.
  8. Using snap-ring pliers, insert the retaining ring into the groove inside the handle, securing the cartridge in place.
  9. Reattach the screen and grille assembly.
  10. Solder the leads of the new cartridge to the XLR connector: the BLUE wire goes to pin 2, and the RED wire goes to pin 3.
  11. Insert the XLR connector in the bottom of the handle, again making sure that the wires are not pinched between the connector and the case.
  12. Secure the XLR connector by turning the XLR setscrew clockwise.
