the ball phantom x-line and y-line crossing point.
Figure 111
The lights 1 and 2 should coincide the ball phantom x-line, and the light 3 should coincide the
y-line.
NOTE The lights 1 and 2 must be exactly on the x-line, otherwise they deviate from each
other. If you see two parallel lights, the lights must be adjusted, refer to section2.3.3
"Positioning light adjustment" on page E-77.
If the light beams do not coincide with the lines or they are not in focus, they should be
adjusted, refer to section 2.3.3 "Positioning light adjustment" on page E-77. When adjusting
the lights 1 and 2, it might be useful to cover one light e.g. with tape, when adjusting the other.
Remove the C-arm inner cover according to the instructions given in section 3.4 "C-arm inner
cover" on page E-89. Adjust the light.
Mark the crossing point (point a) of the lights (Fig. 112; 1, 2 and 3) to the phantom.
