Anyone having a Hytera SM27W2 microphone coupled to HP785 or HM785?

Problem: I don't manage to adjust the mic gain as it now sends out distored and too loud modulation.

(NF output is ok. Programming buttons is ok.)

Question: Where and how to turn down the mic's sensibility?

The CPS's gain control for the external mic does only adjust a cable connected external mic. The BT one stays too load and distored.

Anyone knowing? (Please no speculations)
