Feature: 1.Easy installation, just insert the bar into the earth 2.It is weather-proff allowing it to work all year-round and in virtually all weather conditions 3.Use solar power to recharge the batteries so it is always working 4.The animal repeller is use ultrasonic wave. 5.The Passive InfraRed sensor (PIR) detects motion and triggers the ultrasonic speaker emitting a tone that people cannot hear but chases away common outdoor pests like dogs, cats. 6.It is a safe and humane way to keep unwanted animals away Specification: Name: Animal Repeller Color: Green Unit dimension: 15(W)x8.5(D)x37(H)cm Power supply: 4 x ‘AA’ NiCD rechargeable batteries Power consumption: Standby = 0.8mAh, working = 15mAh Ultrasonic frequency: 18-40 Khz Coverage area: 30 feet @ 1100 = 2425 square feet Working Principle: The product uses infrared pyroelectric sensor,the sensor is associated with reaction sensitivity and movement direction of the animals.It is not sensitive to radial movement but most sensitive to transverse movement. Therefore,if the animal is stationary or close to the product Straightly without crossing movement,infrared sensors will be unable to work on animals because of Induction failure Usage: 1.Connect the repeller head, pole sections, connecting part and ground stake. 2.The unit is now ready for installation. The location should allow adequate sunlight to keep the batteries fully charged. 3.Turn power switch to ‘ON’ position 4.For best results, kepp the repeller head roughly 9-10 inches above
