Figure D
Telephone Cable Assembly
Feed about 5" of telephone cable through the front panel as shown.
If the loose end of the telephone cable is not already stripped, strip off 1 1/2" of outer casing to expose the
four wires. Be careful not to cut into the four wires inside the casing. Cut off the outside wires as shown in
Figure E. Lay the cable out flat with the top side of the connector facing up as shown in the figure, be sure
that the cable is not twisted. Cut the wire shown in the figure to 1". Strip the insulation off of both wires 1/4".
Connector
Insert the telephone cable through the hole in the PC board from the top legend side as shown in Figure F.
Connector
Insert the 1" wire from the foil side into PC board hole J2 (see top legend for location). 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 1 1/2" wire into PC board hole J1 from the foil side. Solder into place.
