The BORHOOD D219 features an intuitive control panel on its top surface. Once plugged in, the device will activate. You can select different modes and power levels to suit your needs.
4.1 Control Panel Overview
The control panel includes buttons for power, mode selection, and flashing light activation. Indicators show the current output power (Small, Medium, Large) and the active repelling wave type (Ultrasonic, Pressure, Electromagnetic).
4.2 Repelling Modes
The device offers three primary repelling modes, each utilizing a different type of wave:
- Ultrasonic Wave: Emits high-frequency sound waves that are generally inaudible to humans but highly irritating to pests.
- Pressure Wave: Generates varying pressure pulses that disorient and disturb pests.
- Electromagnetic Wave: Creates an electromagnetic field that interferes with the nervous system of pests.

5. Maintenance
- Cleaning: Wipe the device regularly with a dry, soft cloth to remove dust. Do not use water or any cleaning solutions directly on the device.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not turning on | No power supply; faulty adapter; device malfunction | Check if the power adapter is securely plugged into both the device and the wall outlet. Try a different outlet. If the issue persists, contact customer support. |
| Reduced effectiveness against pests | Obstructions blocking waves; device placed incorrectly; pests have adapted | Ensure the device is placed in an open area without obstructions. Consider relocating the device to a different spot. Try switching between different repelling modes (Ultrasonic, Pressure, Electromagnetic) to prevent pest adaptation. Allow sufficient time (up to 4 weeks) for full effectiveness. |
| Audible sound from the device | Pressure Wave or Electromagnetic Wave mode active; normal operation for some modes | The ultrasonic wave is generally inaudible to humans. However, the pressure wave and electromagnetic wave modes may produce a subtle sound. This is normal. If the sound is excessively loud or unusual, contact customer support. |
