The Medians A16 AED unit is supplied with a protective outer lid and once removed clear instructions for use are visible. The defibrillator pads are pre-connected and stored in a foil pouch that can be opened when ready to apply to the casualty. Once the Mediana A16 is turned on a combination of LED indicator lights and clearly spoken audible voice prompts, make the AED simple and safe to use even by untrained persons. Visual icons are clearly defined to assist the user, and the clever addition of a button to change the machine from Adult to Paediatric mode (or vice-versa), means the pads are suitable for both adult and child. Language button allows users to select English, Welsh and Polish language. Suitable for a wide range of workplaces including schools and places where children are present.
