2. View the raw image of the nozzle as follows:
[Press the CCD Monitor tab at the bottom of the screen] → [Select the Wide or Narrow camera]
3. The CCD monitor will appear on the screen. Press [SCALE] to display the crosshairs.

6. To align the Wide Camera nozzle image to the crosshairs in the X-direction, loosen the X-axis
positioning bolts (Item 1 in figure 5) and adjust the position of the camera accordingly. Once the
adjustment is complete tighten the bolts with the required amount of torque (8N.m).
7. As the narrow camera bracket is attached to the wide camera bracket, it is necessary to adjust the
wide camera bracket first when adjusting both cameras. Performing narrow camera adjustments first
will necessitate the adjustment being performed twice.
8. To adjust the narrow camera in the Y-direction, loosen the Y-axis positioning bolts (Item 1 in figure 7)
and adjust the camera position accordingly. Once the adjustment is complete, tighten the bolts with
the required amount of torque (13N.m).
