BEFORE USE
Outline of Partial Step

• For this Operator’s Manual, it is assumed that the Partial step license software has been
already installed to the Ice 900 and Me 1200.
• Software version requires the following condition:
Ice 900 Main: V1.03 or later
Me 1200 Main: V1.05 or later
Partial step beveling refers to the process to bevel a
portion of the thick lens edge into a step to fit into
frames so that only a part of the edge is inserted and
protrusions are provided on the lens to hook into indentations in the frame groove.
These frames are mainly used as sport sunglasses. To
use prescription sunglasses with these frames, the
partial step is useful.
This manual describes the procedure from data creation to lens processing for frames that need partial
Sectional view of step beveling
stepped lenses.

Creation of Partial Step (Ice 900)
2.3.1
Preparation and measurement of demo lenses
1
Remove the demo lens from the frame and clean up the lens.
When the part of the demo lens that is inserted into a frame groove is dirty, the measurement may not be performed properly.
2
After attaching the demo lens to the frame, mark the demo lens with a lensmeter.
Refer to “2.6.3 Preparation for demo lenses (Page 99)” in the Ice 900 Operator’s Manual.
3
Roll out the specialized clay and adhere it
to the rear surface of the demo lens along
the frame.
1) If the specialized clay sticks to the
nose pad, the specialized clay may
not come off easily. To prevent this,
remove the nose pad before adhering
the specialized clay.
2) Leave a very tiny gap from the frame
so that the specialized clay and frame
do not touch. When adhering the specialized clay, be sure not to squeeze it
to the extent that it sticks to the frame.
Specialized clay
• Minimize the gap between the specialized clay and frame as much as possible, as it affects
the accuracy of the DBL input.
• Keep the specialized clay from sticking to the frame, or entering the gap between the demo
lens and frame. If this occurs, when the demo lens is removed, the part of the specialized
clay sticking to the frame may become stretched and desired step shape is not achieved.
• The shape may be detected by using a pen to trace the frame instead of specialized clay.
However, detection of the trace data is lower quality than that for the specialized clay.
3) The gap between the clay and edge is beveled with a step.
20
OPERATING PROCEDURE: Creation of Partial Step (Ice 900)
4
Adjust the gap between the specialized clay and edge for step beveling.
• Be sure that neither end of the specialized clay protrudes from the demo lens edge.
• Should nose pad not be removed, or is non-removable, adhere the specialized clay around
it so that the step beveled lens and nose pad do not interfere with each other.

No gap between frame and specialized clay
Remove the demo lens from the frame.
Clean off any stains such as fingerprints
on the lens, as they affect detection.
If the specialized clay sticks to the frame
and is stretched out with the lens
removal, use the spatula to push the specialized clay to the inner side so that the
specialized clay shadow becomes
smooth when the lens is placed on the
Ice 900.
If the specialized clay sticks to the frame
and is defomed along with the lens
removal, reform the shape with the spatula.

When the layout values such as PD is imported with blank, the data can be input on the Me 1200.
However, the layout values that are input on the Ice 900 cannot be changed on the Me 1200.
• The lock of the partial step data that has been imported to the Me 1200 can be released by
pressing the Layout lock button. However, the mode is switched to the Step beveling mode
and the partial step beveling is be performed.
When the lock is released, the processing image is changed to the normal step beveling image shown in the picture to the right.
