Fig. 2 Microphone plug wiring

1. Remove the retaining screw

2. Unscrew the housing from the pin receptacle body

3. Loosen the two cable clamp retainer screws.

4. Feed the microphone cable through the housing, knurled ring and washer as

shown Fig. 2.

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 of the front panel. The numbers of the pins 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.

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.
