KEMO M071N repellent 4 speakers 10-40kHz

M094N sends aggressively pulsating ultrasonic waves which animals perceive as very disturbing and uncomfortable. The device can drive off rodents, dogs, cats, insects, birds, therefore includes a turning control button, that allows to adjust the transmitted frequency continuously from the lower audible frequencies up to ultrasound 40kHz.

In vehicles it is installed in higher levels in the engine compartment (the unit is not waterproof). In the EU it is essentially required that the electric repellent devices must have been installed so that they can be active only when the car engine is turned off, never while the engine is running. Therefore the unit must be connected to permanent PLUS pole and to MINUS which appears only while the engine is turned off. Also 200 mA fuse (not included in the package) must be added to plus cable of the unit.

Values indicating which frequencies may be used with each animal in order to achieve best results:
Birds approx. 10 kHz: control position 3 - 4
Rodents approx. 24 - 32 kHz: control position 7 - 8
Insects approx. 27 - 35 kHz: control position 8 - 10
