I have noticed that I have had some of the Mitel branded DECT headsets start giving the out of range beeps, but even when they are a few inches from the phone. I have to pull the battery but then it starts again if I reconnect. I have just replaced them, but I thought I would see if there was something I can do. Does this mean the device is dead? This happens on various phone models, have 5330, 5340. They are connected to a 3300 MXIII
Anyone else see this. Sometimes if I can get it back into the pairing mode then I can re-pair it and then it works. Some of these are getting pretty old.
Thanks,
Carlos
