Abstract
An interface module for a digitally programmable hearing instrument is detachably connected to the programming system by a cable and plug arrangement and has three large contact surfaces on an insertion module body that fits into a battery receptacle of the hearing instrument so that programming signals from the programming system can be fed to control the response of the hearing instrument. The interface module contains an electronic circuit unit that is detachable so that various interface circuits, such as a decoder, a processor, a level matching circuit, or an impedance matching circuit can be selectively included in the interface module. Each interface module can be color coded so that it can be associated with the proper left-ear or right-ear hearing instrument.
