• Manual alignment of lenticular and occupational lenses is recommended.
Occupationals could be aligned upside down in automatic mode.
• In the case of extreme prism >6 diopters, the prism accuracy is good, but the lens may
be tilted to such a degree that cylinder accuracy decreases and spheres may show some
cylinder. This can be eliminated by holding the lens so that the front curve is parallel
to the glass plate when you insert it into the chamber and then select START and let
the clamps close on the lens in that position. It will then process normally.
