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.
