Abstract
Abstract An apparatus for use in adjusting a secondary adjustment device of a hearing aid consists of an adaptor that can be so placed on the hearing aid that the adjustment device of the hearing aid becomes coupled to corresponding moving elements on the adaptor. These moving elements are in turn coupled to their respective activation controls on a control desk through respective wires in a bowden cable, enabling the secondary adjustment device of the hearing aid to be adjusted by manipulating the activation controls at the control desk.
