This ultrasonic generator produces very loud and aggressive ultrasonic sounds pulsating like a siren, which many animals perceive as extremely unpleasant and, therefore, try to avoid them as far as possible (very often, but not always!). The generator should be used to keep away rodents, insects, crawling parasites, game and birds. If larger areas shall be exposed to ultrasound up to 2 additional loudspeakers L020 may be connected (not enclosed). The audio frequency may be adjusted between ultrasound (not audible to men) and loud + high sounds that are audible to men.
