How do I activate and deactivate the Child Lock on the WAW285H2?

To activate or deactivate the Child Lock, press and hold the Finish In buttons (M and N) simultaneously for approximately 3 seconds. When active, the Child Lock symbol (D) will appear in the display field. Note that the Child Lock remains activated even after the cycle ends and after switching the appliance off and on, so you must manually deactivate it using the same button combination. (Page 37)
