The operating method is based on the simultaneous application of FM and AM, and is distinguished by passing through three operating states, specifically a warm-up phase, an impressing phase and the continuous operation. In the warm-up phase, the f002_hor is selected as fundamental frequency of the AM, or an AM is dispensed with. The impressing phase is distinguished by a temporally changing AM deviating from the conditions of the continuous operation and having an AM degree different from zero. In the continuous operation, constant conditions of the AM in the case of which the f002_hor is reached as fundamental frequency of the AM, and the AM degree is at 20 to 25% are characteristic.
