OPERATION

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.

OPERATION

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.
