receptacle. 

 

Be sure that the housing and the knurled ring of Fig. 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. 

 

If the microphone jack is used to hold the pin receptacle during the 
soldering operation, best results are obtained when the connections to 
pins 1 and 3 are made first and then the connections to pins 2 and 4. 
Use a minimum amount of solder and be careful to prevent excessive 
solder accumulation on pins, which could cause a short between the pin 
and the microphone plug housing. 

 

6.  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 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 the place to secure 
the housing to the pin receptacle body. 

 

7.  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. 

 

8.  Upon completion of the microphone plug wiring, connect and secure the 

microphone plug in the transceiver.
