 |
| The electronic device for deterring harmful birds (BS-20L) offers a variety of operating modes and functions to adapt to the diverse needs of the user. |
| Operating modes | Description | |
| Manual |
 |
In this mode, the user has the freedom to choose a specific song from the list of available songs, ranging from C1 to C10. Once the desired song is selected, the bird deterrent will begin playing only that track, using the times set through the menu. These times, including the Operating Time (OT) and Pause Time (PT), can be adjusted by the user to ensure optimal device operation. |
| Automatic |
 |
Provides greater convenience to the user. In this mode, the deterrent is preset with a series of programs, identified from P1 to P9, which automatically configure the device with the right timings based on our accumulated experience over time. By choosing one of the preset programs, the user can activate the deterrent without having to manually adjust the operating and pause times. The only operation required in this mode is the possible adjustment of the volume, which can be increased from 12 to 14 to ensure effective deterrence of harmful birds. |
| Custom List |
 |
This mode offers the user the possibility to create a personalized song list, composed of 2 to 5 tracks, which will be played sequentially. However, unlike the automatic mode, the user has complete control over the playback times of each song, which can be manually adjusted through the device menu. This allows the user to maximize the customization of the deterrent, adapting it to their specific needs for deterring harmful birds. |
| Operating mode | Description | |
| Daytime Operation |
 |
This mode activates the sound deterrent during the day and automatically deactivates it at sunset. Ideal for protecting environments during daylight hours. |
| Night operation |
 |
In this mode, the sound deterrent is active during the night and automatically turns off at the first light of day. Great for protecting environments during nighttime hours. |
| Continuous Operation |
 |
This mode keeps the sound deterrent active continuously for the entire duration of 24 hours. Ideal for situations where constant protection is required, day and night. |
