Cenocco Home CC-9097: 2 in 1 Advanced Ultrasonic and Electromagnetic Pest Repeller Protect your family from pests and the diseases and nuisances associated with them with Cenocco CC-9097, an advanced 2 in 1 ultrasonic and electromagnetic pest repeller. This pest repellent uses the latest in ultrasonic technology. High-pressure sensor, not a powerful ultrasound that a normal speaker can't hear. Unheard by humans or pets, their sounds beat the eardrums of the tiny critters that invade your home. Like a loud siren, the sounds attack the pests intermittently to drive them out. The device works by changing the existing electromagnetic field in your home or workplace. It sends a short burst or pulse of electromotive force through existing wiring, while also being imperceptible to people or pets and driving pests from their hiding places and out of your building. Plug the product into the power outlet and check that the power is turned on. The red light is on when the device is working. The yellow light is for the electromagnetic function and the green light is for the ultrasonic function. The flashing amber light indicates that the electromagnetic function is working properly. The flashing green light indicates that the ultrasonic function is working properly. Leave the appliance on 24 hours a day, 365 days a year.
