5. The wires must now be soldered to the pins as indicated in the above wiring tables.
If a vise or clamping tool is available it should be used to hold the pin receptacle
body during the soldering operation, so that both hands are free to perform the
soldering. If a vise or clamping tool is not available, the pin receptacle body can be
held in a stationary position by inserting it into the microphone jack on the front
panel. The numbers of the microphone plug are shown in Fig. 3, as viewed from
the back of the plug. Before soldering the wire to the pins, pre-tin the wire
receptacle of each pin of the plug.

6. Be sure that the housing and the knurled ring of Figure 2 are pushed back onto the
microphone cable before starting to solder. If the washer is not captive to the pin
receptacle body, make sure that it is placed on the threaded portion of the pin
receptacle body before soldering.
7. If the microphone jack is used to hold the pin receptacle during soldering operation,
best results are obtained when the connections to pin 1 and 3 are made first and
then the connections to pins 2 and 4. Use a minimum amount of soldering and be
careful to prevent excessive solder accumulation on pins, which could cause a short
between the pin and the microphone plug housing.
8. When all soldering connections to the pins of the microphone are completed, push
the knurled ring and the housing forward and screw the housing onto the threaded
portion of the pin receptacle body. Note the location of the screw clearance hole in
the plug housing with respect to the threaded hole in the pin receptacle body. When
the housing is completely threaded into the pin receptacle body, a final fraction of a
turn either clockwise or counterclockwise may be required to align the screw hole
with the threaded hole in the pin receptacle body. When these are aligned, the
retaining screw is then screwed into place to secure the housing to the pin
receptacle body.

9. The two cable clamp retainer screws should now be tightened to secure the housing
to the microphone cord. If the cutting directions have been carefully followed, the
cable clamp should secure to the insulation jacket of the microphone cable.
10. Upon completion of the microphone plug wiring, connect and secure the
microphone plug in the transceiver.
