How to Change the Frequency on an Invisible Fence Collar

An invisible fence keeps dogs and cats inside the yard without a traditional fence. Pets receive a mild shock and typically learn to avoid the boundaries after three or four training sessions. Pet owners get peace of mind that their pets won't run away or be hit by a car, and pets have the freedom to run around the yard without supervision. While the collar is not designed to harm animals, not all pets will respond to the shock the same way and you may want to adjust the frequency.

The desired frequency depends on the size of the dog. Larger dogs typically need 10k, while smaller breeds usually respond to the lower 7k frequency, but each dog is different and you may not know until you test the system yourself.

Instructions

    • 1

      Examine the receiver to determine the frequency. Some collars come with only one frequency (most brands are 7k or 10k), while others are adjustable.

    • 2

      Use a screwdriver to open the invisible fence transmitter.

    • 3

      Locate the switch, "SW1," that toggles between available frequencies. Refer to the owner's manual if the switch cannot be located or you have difficulty opening the transmitter.

    • 4

      Flip the switch to desired frequency. Double check that it matches the frequency on the collar.

    • 5

      Replace the cover.
