Haierc outdoor garden bird scare repeller HC1701
The device uses ultrasonic waves and a powerful white flashing LED strobe siren to repel a variety of animals.
That ultrasonic frequencies are generally beyond the range of human hearing.
Therefore, if you do not hear any sound when the device is turned on, especially in modes 2 and 3, this should not be interpreted as an indication of a malfunctioning device or that the device is not working. The device is functioning as intended; the ultrasonic frequency is simply inaudible to humans. that when you set it to 4 or 5, the device will continue to alarm when the human body is in close contact with the device. When the human body leaves the device, it automatically goes to sleep.
Different animals, even of the same species, may have varied reactions to each mode of the repellent. Should you find a particular mode ineffective, we recommend trying others to find the most suitable one. This process might require some patience, as identifying the optimal setting can take time – typically around two weeks. Experimenting with various modes is key to achieving the best results with the animal repellent.
