Press RETURN when you have finished setting date and time to save your chosen settings.
Once the screen has reverted back to temperature, you can now adjust Filter Cycles. NOTE: You do not
necessarily have to adjust the Filter Cycles because the default factory settings give you two Filter Cycles
per day automatically. In any case, to access the Filter Cycles, press the MENU button.
This time select Filter Cycles. (Press the MENU button to access the sub-menus.)
