How do I run the Calibration cycle on my Samsung WW90CGC0EDAB?

To run Calibration, power off then power on the washing machine, then hold down Temp. and Delay End simultaneously for 3 seconds until the 'Cb' message appears. Press Start/Pause to begin the cycle, and the drum will rotate for about 3 minutes. When complete, '0' appears on the display and the machine turns off automatically. Make sure the drum is empty before running Calibration. (Page 28)
