Tone Codes for Signia Cros


I’ve had a set of Signia CROS aids for about 2 years. Just today they started emitting a short series of tones that I do not recognize. Like when the batteries are low but a totally different “melody”. Can anyone direct me to a source where I can identify what this tone means. (The batteries are fine and they seem to work as usual)


I know some hearing aids have a tone when they are needing a service. Maybe that was it?


That is quite possible. But I would love to know how to stop it.
