How do I save my customized drink settings for a specific time of day?

As long as the Coffee Routines function is active, whenever you change the settings (such as quantity or intensity) for a drink, the machine will give you the option to save the new settings for that particular period of the day. You just need to tick the dedicated box and confirm with 'Yes'. Make certain that the time on the machine's clock is set correctly for this feature to work properly.
