Programming specsavers Advance 870

Hi,

try to program the Advance 870 (Specsavers)
This HA seems to be an Unitron,

however TrueFit do connect to the HA’s (via NOAHlink Wireless), and state: detection error, Unknown Hearing Aid, or non supporting firmware

Someon a clue

Tried it with TrueFit version 4.3.1 and 5.0

Specsavers are locked hearing aids. You’ll need a special code to program them.

I guess a special firmware? I do not see a possibility to enter a code or so…

I know with Phonak that you enter the ‘special’ code when you install the software not after.
