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.

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.

MAINTENANCE AND ADJUSTMENT

This transceiver is specifically designed for the environment encountered in mobile

installations. The use of all solid state circuitry and its light weight result in high

reliability. Should a failure occur, however, replace parts only with identical parts. Do

not substitute.

If the performance described in the OPERATION section is not

obtained, review the operating instructions to insure that proper

procedures were followed.

FCC WARNING

All transmitter adjustments other than those provided on front

panel by the manufacturer must be made by or under the

supervision of the holder of an FCC issued general radio

telephone operator's license.
