If there is a shield around the telephone cable, it may be
connected to "G" on the terminal block. To avoid ground
loops, connect the shield at the computer end only. A ground
wire is not necessary for proper operation of the Model
1010B.

Refer to the diagram below to confirm that you have correctly
assembled the device.
8.
Place the 2 halves of the strain relief assembly on either side
of the telephone wire and press together very lightly. Slide the
assembly so that it is about 2 inches from the terminal posts
and press together firmly. If your cable diameter is too small or
too large for our strain relief, please contact our technical
support. We have strain relief assemblies to accommodate
most cable diameters.
