Searching a Widex Inteo Micro programm cable

Hello dear friends
I,m seaching for an programming cable (HI-Pro).
It is for a pair of older Widex Inteo Micro HA.
One end of the cable was put into the battery hole. The other side is for Hi-Pro or 4-Pin Connector.https://forum.hearingtracker.com/uploads/default/optimized/3X/b/0/b07987e8ea69ab926cc7d8c40aadd372d74d791b_2_1035x193.png
