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.
NOTE
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.
