The unit is to be used with the portable base unit which creates an “forbidden” zone of 6-10 feet. Simply attach the Collar Unit (tag-sized transmitter) to your pet’s collar and when the pet enters the offlimits zone, the transmitter sends a signal to the base unit. The tone is a safe, but annoying ultrasonic tone, inaudible to humans.
Additional transmitters are great for multiple-pet homes.
