Where is Nivo Concentrator?
At least on eBay, the Nivo Lite is one of the most common machines. One of mine is signaling a red light.
Do you mean Nuvo Lite? If that’s the unit you are describing the manufacturer is Nidek Medical. If the unit is signaling red it could mean a failure somewhere in the system. Here is the link for the resources section. Download the Service manual for your model which is the Nuvo Lite.
