The way in which the device is controlled.

The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
