Feature:1. Advanced: generate electromagnetic wave and ultrasonic wave at the same time.2. Frequency: change constantly and intermittently, but not periodically.3. Adjustable wave band: 1 band(25-70KHz) and 2 band(10-70KHz) for different situations.4. Comfortable: with nightlight function, soft blue light can also boost the repelling effects.5. Safe: use physical method, non-toxic, no harm to human beings or pets.6. Powerful: the effective conservation range is about 150 square meters under open environment.7. Suitable for using in household, office, supermarket, hotel or storehouse, repelling pests effectively.Specification:The product adopts the latest microelectronic technology that can produce extremely low frequency electromagnetic wave and high-frequency wave intermittent alternately, which can deter unwelcome pests, like mouse. The wave makes the pests feel uncomfortable and the nightlight makes the them be scared, so the pests will flee away.Features:Advanced: generate electromagnetic wave and high-frequency wave at the same time.Frequency: change constantly and intermittently, but not periodically.Adjustable wave band: 1 band(25-70KHz) and 2 band(10-70KHz) for different situations.Comfortable: with nightlight function, soft blue light can also boost the repelling effects.Safe: use physical method, non-toxic, no harm to human beings or pets.Powerful: the effective conservation range is about 150 square meters under open environment.Suitable for using in household, office, supermarket, hotel or storehouse, repelling pests effectively.Specifications:Color: WhiteMaterial: ABSVoltage: AC 110-230VPlug Type: US / EU(Optional)Power: 6WElectromagnetic Wave Frequency: 0.8Hz-8HzWave Frequency: 1 Band: 25-70KHz; 2 Band: 10-70KHzconservation Range: About 150 square meters under open environmentItem Size: 90 * 60 * 33mm / 3.54 * 2.36 * 1.3inItem Weight: 83g / 2.93ozPackage Size: 12.5 * 9.5 * 7.2cm / 4.92 * 3.74 * 2.83inPackage Weight: 136g / 4.8ozNote:1. This product cannot be used in these countries like Norway, Poland, Austria, Spain and France.2. Please choose 1 band High-frequency Wave if you raise pets at home, because 12-20KHz high-frequency wave would have some effects on pets.3. It's normal reaction when you find the mouse more active for first use. After using for 2 weeks, you can see obvious effect.Package List:1 * Electronic Pests Repeller1 * User Manual(English).Package List:1 * Electronic Pests Repeller1 * User Manual(English)
