Specsavers Advance Elite - what Signia model might I have been given?

Hi, new hearing aid user here. I bought a pair of Specsavers Advance Elite this week. The audiologist mentioned that they were Signia brand, and I was wondering which model they are likely to be?
She progammed them with Automatic, white noise and a pink noise setting, as well as Induction Loop. The serial number begins with TFK. Other than adjusting the volume, balance and direction (direction only in the automatic programme) there are no other controls. I am finding the pink noise helpful for tinnitus already. Any ideas which Signia model she may have given me? Thanks in advance, and apologies if this has already recently been answered - I can only find replies from some years ago.
