Select calibration mode.
There are three calibration modes: manual (M), semi-automatic (SA) and automatic (A).
Automatic (A)
In the automatic mode the need for calibration is based on software algorithm. Calibration starts automatically.
In the automatic calibration mode, three seconds before automatic calibration a countdown timer is shown in place of the calibration mode icon.
Semi-automatic (SA)
The user determines for himself the need for calibration based on the actual image status.
Manual (M)
Manual (silent) calibration. Close lens cover before calibration.
