Can't pair Rexton accessories to Signia hearing aids

I previously had a Rexton smart remote paired to Siemens Pure Micon aids in Connexx 8.

I have just purchased Pure Primax aids and I cannot pair the remote in Connexx as it gives me an error “CAN ONLY PAIR WITH SAME BRAND OF HEARING AIDS”

I want to buy a Smart Connect (rexton equivalent of Easytek) but not sure if it’ll work either.

Anyone experienced this or know how to circumveme this lock?

Just a guess, but I would suspect the problem is in the firmware of the Rexton Smart Remote. Not sure if one could update the firmware to the Signia version?

Do you have a smartphone that you could download the free Signia app to do the remote functions? I initially used an old smartphone that did not even have a SIM card in it, and just used it as a remote control for my KS8 HA’s.

Yes i am using the SIgnia app with success thankfully. However, it takes a while to unlock phone, open app and make the adjustment. I wouldn’t know how to update the firmware of the Rexton Smart remote but i’ll take a look. Thanks for the suggestion.
