Modular Jack
Cut off the yellow and black wires at the base
of the modular jack (they are not used). Cut
the red and green wires to 4" and strip 1/4" of
insulation off of each wire. The spade lugs (if
any) are not used.
Insert the red wire into hole J3 from the foil side
of the PC board as shown in Figure G. Solder
wire into place.
Follow the same procedure with the green wire, except insert it
into hole J4.
Wire Meter to PC Board
Cut a 4 3/4" wire from the 7 1/2" solid black wire. This will leave
you with a 2 3/4" wire. Strip 1/4" of insulation off both ends of
the wires.
Insert the 4 3/4" wire into PC board hole J6 from the foil side.
Leave enough bare wire exposed to solder the wire to the pad,
about 1/8". Solder wire in place and cut off the excess wire
from the top legend side of the board.
Insert the 2 3/4" wire into PC board hole J5 from the foil side.
Solder in place and cut off the excess wire from the top
legend side.
Solder the loose end of the 2 3/4" wire from PC board hole J5
to the positive (+) lug on the meter as shown in Figure H.
Solder the loose end of the 4 3/4" wire from PC board hole J6
to the negative (--) lug on the meter.
FINAL ASSEMBLY
Place the jack into the hole in the case labeled "INPUT"
as shown in Figure I. The green and red wires should be
positioned below the telephone cable.
Align the PC board with the top panel and attach it to the
spacers with two 4-40 x 1/4" screws. Make sure that
the telephone lays flat between the PC board and
the jack (see Figure J).
Mount the PC board to the front panel as shown in
Figure I with two #4 x 1/2 phillip screws.
Pull the excess telephone cord through the front of the
panel.
