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.
1. 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.
2. 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.
3. Upon completion of the microphone plug wiring, connect and secure the
microphone plug in the transceiver.
