Pre-Setup (for all HFA II - i models)
1) Push the tool stand forward slightly on the chinrest so that the metal tips on the Tool
Stand Alignment Adaptor make contact with the headrest (Figure 4-10). Then raise the
trial lens holder and pull it forward. This is the position that the tool stand should be in
when performing the procedure.
2) The right-angle extension on the fake eye assembly will press against the trial lens
holder and position it correctly (Figure 4-11). (Set the chinrest height so that the right-
angle extension touches the trial lens holder at about the 0 - 0 level on the trial lens
holder scale.)
NOTE: Once you have the trial lens holder set, do not move it.
3) From the Calibration main menu, select Camera , then Position , and then Camera
Monitor.
4) By using the menus, move the trial lens holder image left or right, until the left outer
edge of the trial lens holder image is touching the left edge of the video insert; then
select
X-5
(5 more steps to the left), and
