Marten and rodent repellent KEMO M094N for car

It emits pulsating aggressive ultrasound waves that animals perceive as very disturbing and uncomfortable. The device can drive away rodents, dogs, cats, insects, birds, therefore it contains a rotary control, which can be used to smoothly adjust the transmitted frequency from lower audible to medium at the limit of audible, up to ultrasound up to 40kHz.
In vehicles, it is installed higher in the engine compartment (not waterproof). In EU countries it is fundamentally required that tick repellers are installed so that they can only be turned on when the car engine is turned off, never when the engine is running, therefore it is connected to a permanent PLUS half and a MINUS that appears only when the ignition is turned off, perhaps also insert a 200mA fuse (not included in the package) on the plus wire of the unit.
