insert the entire piece through the hole in the DB-25 end of the case.
Snap that side of the case closed.  Repeat the process for the other
side.  This completes the installation process.

4.  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.

5.  Insert the strain relief assembly and the wire into the slot in the

bottom half of the modem case.  Set it into the recess in the case.  (If
the telephone wire does not fit into the strain relief assembly, call Patton
Electronics Technical Support at 301-975-1007.  We have strain relief
collars to suit a variety of cable diameters.)
