KEMO M094N Repeller 4x Speaker 10-40kHz

M094N emits pulsating aggressive ultrasonic waves that animals perceive as very disruptive and uncomfortable. The device can repel rodents, dogs, cats, insects, birds, therefore it contains a rotary controller, which allows the transmitted frequency to be smoothly adjusted from lower audible through medium at the threshold of audibility, up to ultrasound up to 40kHz.

In vehicles, it is installed higher in the engine compartment (it is not waterproof). In EU countries, it is fundamentally required that devices for repelling horses be installed so that they can only be switched on when the vehicle's engine is off, never when the engine is running, therefore it is connected to a permanent PLUS pole and a MINUS that appears only after the ignition is turned off, a 200mA fuse (not included) should also be included on the plus wire of the unit.

Values indicating which frequencies can be used for individual animals to achieve the best results:
Birds approx. 10 kHz: position 3 - 4
Rodents approx. 24 - 32 kHz: position 7 - 8
Insects approx. 27 - 35 kHz: position 8 - 10
