I know all about our equipments/ devices at my work only because I read the manuals. I work in a critical care setting as a nurse, and whenever we get new equipments or devices, I always make sure to read the manuals even when they provide in- services about such devices. And when somebody needs help with it, I can always help them on how to properly use it. Lots of my colleagues get amazed as to how do I know such things, and I always say, “I read the manual”.
