The beam from the soft tissue filter positioning light must strike the line on the beam alignment
tool marked "Positioning light 0mm" and the number on patient positioning display must be 00. If
the light is in the wrong position it must be repositioned and if the display number is wrong it must
be recalibrated. If the light beam itself is crooked or out of focus the lens or mirror must be repo-
sitioned. Refer to the section "Soft tissue filter positioning light calibration and adjustment" on
page D-40.
