The present invention relates to a novel process for preparing sulfamoyl-substituted phenethylamine derivatives, specifically, 5-{2-2-ethylamino-propyl}-2-methoxy-benzene sulfonamide of the formula. An interconnection point is provided at the chip in the form of a bump contact in weldable material. The first panel has a battery holder configured to retain at least one battery therein. A break point is determined for each action type at which a response time exceeds a predetermined threshold.
