The PetSafe Wireless Fence requires no buried wires like conventional containment systems, making it ideal for persons who travel or relocate frequently. The IF-300 uses a centrally-located transmitter which is installed indoors to send a circular radio signal through the walls of the house and outside into the lawn. Installation time from box to a fully-functioning system is typically less than 30 minutes! The radius of the circular containment area is adjustable from 5 feet up to a maximum of 90 feet from the transmitter. An additional IF-100 Transmitter may be purchased to create a separate containment area, or overlap two transmitters to create a larger containment area.

As the dog approaches the boundary of the circular pattern, the collar will beep to warn the pet. If it continues to approach the boundary, the collar will administer a correction to the pet. If your pet leaves the containment field, he will receive a correction for 27 seconds or until he returns to the containment area. The IF-275 receiver allows you to choose from 6 levels of correction strength [1 (low) to 5 (high) plus beep only mode] to match the receiver to each pet's temperament. In the event of a power failure, the collar is designed to recognize the signal deterioration as a power failure and will not administer a correction.
