An electronic fence system capable of guiding animals under training to
return to a predetermined restricted area. The electronic fence generates
electric shocks as the animals attempt to leave the predetermined
restricted area and restrains the electrical shock when the animals
return to the predetermined restricted area. The electronic fence
includes a transmitter and a receiver. The transmitter transmits RF
signals having a plurality of control signals such that different shock
levels are generated responsive to the location of the animals within the
predetermined restricted area. The receiver sets a shock wave level,
selectively controls the generation of the electric shock and a
high-frequency beep, automatically restrains the generation of the
electric shock when an escaped animal returns to the predetermined
restricted area, and generates an audible alarm and turns lamps on and
off to indicate the location of the animal when it escapes from the
predefined restricted area.
