receiving a request for fine tuning a setting of a digital signal processor of the hearing aid system;

carrying out a hearing aid performance verification in response to receiving the request; and

carrying out the requested fine tuning only if the hearing aid performance verification is carried out with a successful result; and

wherein the receiving the request comprises at least one of a user interacting with a fine tune controller in the hearing aid or with an external device that is part of the hearing aid system and that transmits a request to the fine tuning controller; and

wherein the instructions when executed by a computer further cause the fine tuning controller to carry out a hearing aid feedback test before carrying out at least one of a wax congestion detection and microphone performance test; and cause the fine tuning controller to not carry out at least one of the wax congestion detection, ear piece positioning and the microphone performance test if a result of the feedback test is within a range of expected values.
