My tbi pro ultrasonic repeller makes a weird noise when the light is red. Is That normal? After a while that noise becomes annoying. The light constantly switches from green to red.
Switch the device so that only the green indicator is on and see how the device operates. If the problem persists, please let us know and we will replace the device.
