What does a ‘Battery Error See Manual’ message mean?
This message is displayed on Inogen oxygen concentrators. A battery error has occurred. Switch to a new battery or remove the battery and operate the concentrator using an external power supply. If the battery error recurs with the same battery, stop using the battery. Your battery or concentrator may be faulty. If the message persists the concentrator may need a service.
This is a low-priority alert message and is accompanied by a double beep and a solid red light.
