(4) With the degaussing tool still energized, slowly
back it away from the screw until the tool is at least
2 feet from the screw head, then unplug the tool.
(5) Place an 8-1/2 X 11 inch piece of paper, oriented
lengthwise from front to rear, on the center line of
the roof at the windshield header (Fig. 4). The pur-
pose of the paper is to protect the roof panel from
scratches and define the area to be demagnetized.

tool at least 2 feet away from the compass unit.
(7) Slowly approach the center line of the roof
panel at the windshield header with the degaussing
tool plugged in.

roof panel. Using a slow, back and forth sweeping
motion and allowing 1/2-inch between passes (Fig. 4),
move the tool at least 4 inches either side of the roof
center line and 11 inches back from the windshield
header.
(9) With the degaussing tool still energized, slowly
back it away from the roof panel until the tip is at
least 2 feet from the roof. Then unplug the tool.
