Excelon Operator’s Manual 27
LEFT / BOTH / RIGHT
• BOTH : for two eye tracing. This is only for frame tracing.
• R : for right eye tracing.
• L : for left eye tracing.
☞ Usually one side tracing is used for the pattern or demo lens.
☞ The one side traced data for pattern or demo lens is copied symmetrically to the
other side.
• The data will be automatically transmitted after finishing the tracing.
• In case that the single side (R or L) is traced, the traced data will be
automatically duplicated symmetrically to the other side to complete the job.
• Semi-Automatic Tracing Mode will be executed in case of pressing one of these
three buttons, ‘L’, ‘B’ or ‘R’ for more than 3 seconds. It will be useful to trace the
frame with the lopsided groove.
