Does your unit have a backup generator? Mine does. When the power goes out, it stays off less than a minute, till the generator kicks in. When it does, all the machines alarm at the same time, because the power went out. The lights, machines, and tvs stay on in the treatment area, but the waiting area and the nurses break room and offices have no power.
Nope, I'm a four hour run. Honestly I had no idea it was high. No one ever brings it up when we go over my numbers. Speaking of which I have new ones that I will put in later today.
