Yes, just make sure both your hearing aids and the FMA120 are updated to the latest firmware.
From customer feedback, the latest firmware version for your Rexton Reach might be 25.5.1039.3.
For the FMA120, the current version is 1.1.1.7, but you can always check for updates in the FlooCast desktop app.
