The AK-B4100 does not promote growth or proliferation of dirt when submersed for cleaning thanks to the lack of hallow spaces which prevent this from happening. It is both dirt and water resistant and features a Backlighted Sealed Notebook Style Keyboard. It is designed for use in hospitals and can perform around 3 million operations per key. These keys are covered with silicon membrane and consideration placed on ergonomic styling as well to have optimum performance; they are also pleasant to touch with high-quality material used to enhance tactile feel. The adjustable LED backlighting makes it easier to read key aspects of information. When the need arises to clean, the product dries very easily. The design and material used for the keyboard does not allow accumulation of liquids or running off of liquids as well. The surface can be disinfected by spray/wiping.
