• Changing bridge size display option, FPD can be displayed instead of bridge
size(Default option is bridge size).

• In case of Two Eye Tracing, the value of FPD will be automatically transmitted
and displayed.
• In case of pattern tracing, be sure to change the standard value to the actual

is not from frame to frame, but from lens to lens,
