6-2 ) and vertical (item 2 in Figure 6-2 ) directions.
3. Run film loop with Dolby Digital track.
4. Adjust CCD vertical positioning by pivoting entire adjustments assembly (item 1 in
Figure 6-2 ) and fine vertical adjustments (item 2 in Figure 6-2 ) to achieve maximum
video signal on oscilloscope.
5. Adjust with threaded lens (item 5 in Figure 6-2 ) at front of CCD assembly to obtain
highest possible focus reading on DRAS or QC software.
Digital reader has been factory-aligned to meet Dolby specifications.
Field adjustment requires oscilloscope and either DRAS or QC software.
6. Adjust azimuth (item 8 in Figure 6-2 ) to read zero ±2 mils with DRAS or QC software.
7. Adjust lateral positioning (item 6 in Figure 6-2 ) to center image on CCD. It should read
zero ±0.5 mils on DRAS or QC software.
8. Magnification should be 100 ±2%; adjust focal distance if necessary.
