1. The device is on but the sound or the flashing light never turn on.
A. Both the sound and the light have a setting that forces them to stay OFF even when the infrared beam is triggered. Please double check that the top two switches are set to "SENSOR" mode and not "OFF"
2. The sound or the flashing light never stop.
A1. Both the sound and the light have a setting that forces them to stay ON even when the infrared beam is not triggered. Please double check that the top two switches are set to "SENSOR" mode and not "CONT."
A2. The Sensitivity Switch is set too high and the device is being triggered by random motion. Please turn this down.
3. This sound is annoying me or my neighbor.
A. This device is designed to be audible to startle birds, but you can adjust the "Sonic Frequency" slider a little over halfway toward the right to go into an inaudible-to-humans sound. This is less effective for startling birds but at least it won't bother you or your neighbor.
4. It's not working on pigeons or ducks!
A. Honestly, pigeons and ducks are 50/50. Some customers report great success and others get none. We suspect that an adjustment to settings would help the unlucky customers and we are available on Amazon to assist.
