Signia Hicoss

I have a problem with one of my two signia pure 7x. After an evening with louder music, one of the devices starts beeping when there is any louder sound. Does anyone know how to fix this problem?
Audilog has tried everything in connexx and does not know how to solve the problem.t

Just sounds like the beeps to replace the battery.

Its not the batteries

Can you factory reset them in the software and then reload your settings?

So does the HA work as it should otherwise, volume and program changes, no problem in normal everyday situations.
Could it be more of a feedback issue and not “beeps” that your hearing? As far as I know there’s not service tones from Signia unlike Oticon.

I need hicoss program can you help me?

I have seen HICOSS mentioned in some obscure document (see below). But I don’t know of anyone who has used HICOSS. Maybe try using Connexx6.5.5/SiFit6.10 for Signia older/legacy.

Clip from obscure document;

ETA: Also the “Noahlink” mentioned in the obscure document is not Noahlink Wireless. Why? Because Connexx 6.5 cannot use Noahlink Wireless as a hearing aid programming device. It can only use devices, ConnexxLink, Hi Pro, or the old obsolete NOAHlink;
