The only 3V lithium cell is behind the LCD screen but that's for something else because I disconnected that while the control was on and a different alarm popped up & disappeared after I reconnected it. I opened the other working Doosan and that one had NO batteries anywhere to be found either but it has no alarms. So where are they hiding them??? Can they be behind the red cap of the servos?
