How do I calibrate the touch screen on the Essilor Mr Blue 2.0 when it is inaccurate?

The answer

If the touch screen is imprecise, hold the edging screen for 5 seconds to open calibration directly, or select the calibration function from the work screen. Touch each cross precisely with the stylus held perpendicular to the screen.

The manual provides a direct recovery route when inaccurate touch input makes menu navigation difficult.

  1. Press and hold the edging screen for 5 seconds to access the calibration screen directly, or open the calibration function from the work screen.
  2. Press the control to start calibration.
  3. Touch each displayed cross precisely.
  4. Hold the stylus perpendicular to the screen during each touch.
  5. When calibration is complete, return to the work screen.

Holding the stylus at an angle can alter the calibration, so the manual specifies the perpendicular position. The settings menu is displayed automatically once calibration has finished.
