Hearing assistance system and method of operating the same

A hearing assistance system comprising a hearing device, which comprises means for stimulating a user's hearing and which is worn at one of said user's ears, and a remote device spaced apart from said hearing device, said system further comprising:

• means for establishing a wireless link between said hearing device and said remote device for transmitting signals from said remote device to said hearing device,
• means for detecting whether a source of radio frequency signals interfering with said wireless link and having a transmission power changing according to a predictable scheme between low power regimes and high power regimes is present in a vicinity of said hearing device,
• a control unit adapted for operating said system in a base mode unless a presence of such source of signals interfering with said wireless link is detected by said detecting means and for operating said system in an interference mode as long as a presence of such source of signals interfering with said wireless link is detected by said detecting means, in which interference mode transmission of said signals from said remote device to said hearing device is synchronized to said detected power scheme of said interfering signals in such a manner that said signals are transmitted only during said low power regimes.
