- PIR Motion Sensor: Detects movement and body heat of animals within its range.
- Ultrasonic Speaker: Emits high-frequency sounds inaudible to humans but irritating to animals.
- Sensitivity Knob: Adjusts the detection range of the PIR sensor.
- Frequency Knob: Selects different ultrasonic frequencies to target various animal species.
- Mounting Pole/Stake: For ground installation.
- Battery Compartment: Located at the back of the device.

Setup and Installation
Follow these steps to set up your animal repellent:
- Unpack the Device: Carefully remove all components from the packaging. Ensure the main unit, mounting pole sections, and ground stake are present.
- Assemble the Mounting Pole: Connect the pole sections together. Attach the main unit to the top of the assembled pole.
- Insert Batteries: Open the battery compartment on the back of the unit. Insert the included batteries, ensuring correct polarity. Close the compartment securely.
- Choose a Location:
- Select an area where animal activity is observed.
- Ensure the solar panel receives direct sunlight for several hours daily to maintain battery charge.
- Position the device so the PIR sensor faces the area you wish to protect.
- Avoid placing it behind large obstacles that could block the sensor or sunlight.
- Install the Device:
- Ground Installation: Gently push the ground stake into the soil until the unit is stable and at the desired height. Do not force it into hard ground; pre-dig a small hole if necessary.
- Wall Mounting: (Optional) Use the mounting holes on the back of the unit to secure it to a wall or fence using appropriate screws (not included).

Operating Instructions
Once installed, adjust the settings to suit your needs.
- Power On: The device typically activates automatically once batteries are inserted and it detects motion. Some models may have an ON/OFF switch; refer to the specific product label if present.
- Adjust Sensitivity (Left Knob):
- Turn the left knob (labeled "Sensitive" or similar) to adjust the detection range of the PIR sensor.
- Rotate clockwise for a wider and more sensitive detection range.
- Rotate counter-clockwise for a narrower and less sensitive detection range.
- Adjust as needed to avoid false triggers from small movements or distant objects.
- Select Frequency (Right Knob):
- Turn the right knob (labeled "Freq" or similar) to select one of the 5 available ultrasonic frequencies.
- Each frequency setting is designed to target different animal species. Experiment with different settings to find the most effective one for the animals you wish to repel.
- The device may also emit a flash light when motion is detected, especially in low-light conditions, to enhance deterrence.
The PIR motion detector is designed to react only to body heat, minimizing unwanted activations from non-living objects like leaves or branches.

Maintenance
- Cleaning: Periodically wipe the solar panel and the PIR sensor window with a soft, damp cloth to ensure optimal performance. Do not use abrasive cleaners.
- Battery Check: While the solar panel charges the battery, prolonged periods of low sunlight may reduce effectiveness. If the device seems less responsive, check the battery charge or replace batteries if necessary.
- Seasonal Storage: If storing the device for an extended period, remove the batteries and store the unit in a dry, cool place.
