Introduction
The P3 P7825 Under Hood Animal Repeller is designed to deter unwanted animals such as rodents, cats, and squirrels from nesting in or damaging vehicles, garages, barns, and sheds. This battery-powered device emits ultrasonic waves and features an LED indicator to help protect your property.
Safety Information
- Keep the device away from children and pets that are not the target of deterrence. While ultrasonic frequencies are generally harmless to humans, prolonged exposure at close range is not recommended.
- Do not immerse the device in water. Although it is water-resistant, it is not waterproof.
- Ensure proper battery installation to avoid damage to the unit.
- Do not attempt to open or modify the device, as this will void the warranty and may cause malfunction.

Troubleshooting
- Device not turning on: Check if the batteries are installed correctly and are not depleted. Replace batteries if necessary.
- LED not blinking: If the device is on but the LED is not blinking, the batteries may be low or depleted. Replace them.
- Pests still present: Ensure the device is placed in an optimal location with an unobstructed path for the ultrasonic waves. Consider adding additional units for larger areas or if the area has many obstacles. It may take some time for pests to be fully deterred.
