How do I run Calibration Mode after installing the washing machine?

Remove all laundry from the machine, then press and hold Water Level and Delay End simultaneously for at least 3 seconds while the power is on. Press Start/Pause to activate Calibration Mode, and the pulsator will rotate clockwise and anticlockwise for approximately 1 minute. When complete, "0" appears on the display and the machine automatically turns off, indicating it is ready for use. (Page 20)
