Wodondog Invisible Wireless Dog Fence keeps your dog safely in your yard with adjustable radius coverage of the radio signal, 50-200M radius (coverage is reduced when the signal range is blocked by buildings), you can adjust it to the size of your yard, the system can be set up quickly, no wires are needed, after turning on the system After turning on the system, confirm the electronic signal boundary by testing, then train your dog to understand that when the collar makes a sound, it needs to return to the signal coverage (this is important, please don't give it to your dog without training). If your dog steps out of the transmitter's signal boundary, the receiver will beep 3 times and then begin a continuous shock for 3 minutes with a 1 minute pause. Repeat the electric shock for 3 minutes with a 1 minute pause until the dog walks back to the signal boundary. By adjusting the signal strength in levels 1-4, the receiver corresponds to a radius distance of 50-200m, i.e. level 1 is 50m and level 4 is 200m.
