The manner of informing a user about the current setting of manually adjustable parameters in a hearing aid is to be improved. In addition it is proposed that an information signal be transmitted to the user, on the basis of which said user is informed that an upper or lower end of the value range for a parameter to be set has been reached, so that further activation of the relevant actuator remains ineffective in respect of parameter setting. The invention is used in particular in conjunction with actuators which do not have a mechanical end stop, whereby the user could identify that the upper or lower end of the value range of the parameter to be set has been reached.
