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

base 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 and

MAINTENANCE AND ADJUSTMENT sections 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.
