What happens if the DISC PENDANT 100-230V is disconnected from the power supply?

If disconnected from the power supply completely (using, for example, an extra switch) and then reconnected, the light will be in the highest setting when switched on by hand movement. The light will also be subjected to an automatic calibration process the first 15 seconds each time it is disconnected from the power supply. During this time, do not place a hand or conductive objects near the sensor because this will interfere with calibration.
