To wire microphone cable to the plug provided, proceed as follows : 
 
(i)  Remove the retaining screw. 
 
(ii)  Unscrew the housing from the pin receptacle body. 
 
(iii) Loosen the two cable clamp retainer screws. 
 
(iv) Feed the microphone cable through the housing, knurled ring and washer as shown Figure 2-4. 
 
(v) 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 of the front panel. The numbers of the pins of the microphone plug are shown in 
Figure 2-5, 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.

Be sure that the housing and the knurled ring of Figure 2-3 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. 
 
(vi) When all soldering connections to the pins of the microphone plug are complete, 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 counter-clockwise 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 the place to secure the housing to the pin receptacle body. 
 
(vii) 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 insulating jacket of the microphone cable.  
 
(viii) Upon completion of the microphone plug wiring, connect and secure the microphone plug in 
the transceiver.
