The unit is activated by the dogs barking, or can be manually operated with the push of a button to emit a loud ultrasonic tone only dogs can hear. This unit is not waterproof; when operating outside place in a protected area such as under eaves, awnings, or other overhangs, shielding it from rain or moisture.
