Operations DME 11 Chapter

•To change on the z-axis, rotate the Z-ring.

Parameter values increase as you rotate clockwise, and decrease as you rotate counterclockwise.

However, when you have pressed the [LOC XYZ] button to move the image, z-axis parameters increase as you rotate counterclockwise, and decrease as you rotate clockwise.

If you hold down the [SRC] or [TRGT] button while carrying out the above operations, the rate of change of the parameters is reduced. (Fine mode)

5 To restrict the change in the transformation to a specific axis, press the [X], [Y], or [Z] button, tuning it on.

This enables the trackball and Z-ring operations on the selected axis only.
