Abstract

An appliance comprising a programmed digital processor having an integral test procedure and input and output terminals for connection to further parts of the apparatus, including input means and display means. In order to test the input and output terminals of the signal processor and the connections to further parts of the apparatus, further connections are provided from input and/or output terminals of the signal processor, via a plurality of gates which are activated by the signal processor via a further terminal thereof, to other input and/or output terminals of the signal processor. When the test procedure is activated, an indicator indicates whether or not the tested terminal and/or connection is in good order.
