IMPORTANT SAFETY INSTRUCTIONS Protection from damage ~ Do not drop anything on the ceramic surface of the cooktop. Although the ceramic glass is shock and scratch resistant, it is not shock or scratch proof. ~ Do not use pots or pans with pronounced edges or ridges on the ceramic cooktop. These could scratch the cooktop permanently. See "Selecting Cookware" for more information. Grains of salt and sand can also scratch. Make sure that the bases of any pots and pans are clean, free of any fat or oils and are dry. ~ Do not allow either solid or liquid sugar, pieces of plastic or aluminium foil to fall on the burners when they are hot. If these residues are allowed to cool on the ceramic surface pitting or even cracking could occur. ~ Any spills should be removed as quickly as possible to prevent them from burning on and becoming difficult to remove. ~ Do not use a steam cleaner to clean the appliance. Steam could penetrate electrical components and cause a short circuit. ~ Never place hot pots or pans over the display, as the underlying electronics may be damaged. 5
