1. Equipped with a sensitive PIR sensor, it can effectively prevent other animals from entering. Its main functions include repelling insects, deterring pigeons, rats, parasites, cats, and providing balcony protection against pigeons. 2. Ultrasonic modes: - Mode 0: Off. - Mode 1: 13.5 kHz - 19.5 kHz. Deters animals such as rats, dogs, foxes, and minks. - Mode 2: 19.5 - 24.5 kHz. Targets animals including cats, raccoons, and skunks. - Mode 3: 24.5 kHz - 45.5 kHz. Drives away bats, birds, rodents, etc. - Mode 4: Flashing strong light. Deters raccoons, wild boars, minks, etc. - Mode 5: Variable frequency with LED flashing to keep animals and birds away. 3. Cat repeller parameters: - Solar panel: Polycrystalline silicon, 5.5V, 90mA, 3.12*1.70 inches, 45.5kHz. - Charging voltage: USB 5V 1A, fully charged in 3 hours. 4. Notes: - When using the device for the first time, please charge the battery with a USB cable. - The effect of repelling animals does not take place immediately. It may take 10 to 30 minutes, and it takes 15 days to achieve its full deterrent effect. It is recommended to change the frequency regularly. - The device is protected with an IP66 rating, but do not immerse the product in water. If the device is overturned, falls to the ground, or gets splashed in heavy rain, it may be damaged. - If certain functions (such as ultrasonic waves, flashing lights, or sound signals) do not work, the battery may be depleted after a period of time. Try charging the battery.
