System consisting of a household appliance and an external apparatus
First Claim
1. A system for the parameterization, error analysis and remove maintenance of a household appliance, comprising:
- a household appliance;
an external apparatus;
means associated with the appliance and external apparatus for exchanging therebetween electromagnetic radiation in one of the visible light and infrared wavelength ranges by respectively continuously transmitting a first search code in sequences separated by a pause interval and consisting of a plurality of code words differing from each other code and comparing the first search code with a second search code;
means responsive to conformity between the first and second search codes for issuing a response signal after sequentially receiving at least five code words.

Abstract
A system for connecting a household appliance to an external apparatus for the purpose of parameterizing, error diagnosing and remotely maintaining the former by an exchange of electromagnetic radiation signals consisting, on the one hand, of separated sequences of first search codes made up of a plurality of code words differing from each other transmitted to receive an answer signal consisting of a single code word and generated in response to a predetermined number of transmitted first search codes being in conformity with second search codes stored at the device receiving at least a predetermined number of sequences of the first search code.
