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.

of
pin receptacle.
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 4 are made first and then the connections to pins 2 and 3.
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.

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
onto
the pin receptacle body, a final fraction
of
a
turn either clockwise or counterclockwise may be required to align the
