3.3 Blocking Position calibration
Although the cross marker of a optic center is correct at the display, if the blocked position is incorrect for lenses
marked with 3 dots, progressive lenses or bi-focal lenses, it is needed for you to calibrate the blocking position.
Step 1. Put an adaptor at the adaptor holder.
Step 2. Put the lens supporter for the Digital Scanning on the normal lens supporter.
Step 3. Click “BLK CENTER” button at “MENU > CALIBRATION > BLOCKER” page.
Step 4. If the red cross marker and a center hole of the adaptor aren’t coincided as you see in the above picture,
move the cross marker to locate the center of the hole using 4 arrow buttons at the bottom.
Step 5. If you moved the cross marker, press the save button at a top area to apply your calibration.
Step 6. If you repeat from Step 1 to Step 4, you can identify whether your calibration is done correctly or not.
