How the System Works
The Guardian

Underground Fence
pounds. The system works by producing a radio signal from the Fence Transmitter through up to 2000
feet of Boundary Wire. The Boundary Wire is buried or attached to a fi xed object to enclose the Pet
Area. You temporarily defi ne this Pet Area with Boundary Flags for a visual aid in training your pet.
Your pet wears a Receiver Collar with Contact Points that touch his neck, and, once trained, is allowed
to roam freely in the Pet Area. When your pet reaches the Warning Zone, the Receiver Collar gives a
warning beep. If your pet continues into the Static Correction Zone, a safe Static Correction will be
delivered through the Contact Points to get his attention until he returns to the Pet Area.
Key Definitions
Fence Transmitter: Transmits the radio signal through the Boundary Wire.
Pet Area: Area within the Warning Zone where your pet can roam freely.
Warning Zone: Outer edge of the Pet Area where your pet's Receiver Collar begins to beep, warning
him not to go into the Static Correction Zone.
Static Correction Zone: Zone beyond the Warning Zone where your pet's Receiver Collar will emit
a Static Correction, signaling him to return to the Pet Area.
Boundary Width: Combination of the Warning Zone and the Static Correction Zone.
Receiver Collar: Receives the radio signal from the Boundary Wire.
Correction Level Button: Adjusts the level of Static Correction your pet receives in the
Static Correction Zone.
Receiver Indicator Light: Indicates the level of correction at which the Receiver Collar is set.
This light also serves as a low battery indicator.
Contact Points: Deliver the safe Static Correction when your pet moves into the Static Correction Zone.
Power Jack: Where the Power Adapter plugs into the Fence Transmitter. The Fence Transmitter is
powered by a standard 120-volt outlet.
Boundary Wire Terminals: Where the Boundary Wires connect to the Fence Transmitter in order
to complete a continuous loop.
Loop Indicator Light: Indicates that the Boundary Wire makes a complete loop, enabling the signal
to be transmitted.
Boundary Width Control: Adjusts the width of the Warning and Static Correction Zones.
Note: Adjusting the knob does not change the level of Static Correction on the Receiver Collar.
