This hidden A-200 fencing system is among the most reliable, cost-efficient pet containment systems available
today. A buried wire transmits a harmless radio signal. When you dog approaches the boundary, the signal
causes the dog's collar receiver to deliver a warning beep first. If your dog continues closer to the boundary, the
system will issue a mild shock. If your dog continues further, the system will issue stronger shocks until your
dog returns to within the boundary your have set up. Your dog will naturally seek to avoid correction, and is
content staying within established boundaries.
How does it work?
• The transmitter box plugs into a standard power outlet out of the weather, it is NOT waterproof.
• The boundary wire must make a complete loop with both ends connected to the transmitter. A
radio signal travels along the wire and creates a field which becomes the 'Correction Zone'.
The width of this can be altered by a dial on the transmitter. The signal is picked up by the dog's receiver collar
as he approaches the edge of this zone. He will hear a warning beep and then receive a static pulse if he does
not retreat into his pet area as trained. This mild stimulation is harmless; you have probably felt a similar
sensation occasionally from touching a car door or brushing against someone.
The Collar Receiver can be set on different levels to suit the temperament of your dog. If set on level '2' or
higher, the correction level will automatically increase the longer he remains in the 'Correction Zone' to prevent
lingering and draining the battery.
You should change the battery in your dog's collar receiver. If you have a dog that likes to test the boundaries
often, be aware that the battery may run out sooner.
Install an Electronic Pet Fence
• Electronic pet containment is a dog training system that that uses a small electric charge to keep
your dog in the yard. A transmitter plugs into a standard outlet and emits a signal that travels along
underground wires. A hidden boundary is created, and a receiver on your dog's collar sounds a warning tone
when the dog wanders near the boundary. If the dog doesn't back away, the receiver will respond with a mild
but definite static correction. It's harmless, but just uncomfortable enough to make the dog learn the new
customized boundaries and remain in the "safe" part of the yard.
• No one can see the boundaries you've set up, but your dog knows they're there. You can use these
systems to create boundaries your dog can't jump over or dig under, so they are sometimes used to keep dogs
out of flower beds and swimming pools as well confining them to their own yards.
• The charge your dog will feel from the receiver on its collar is slightly stronger than that the shock
you get from static electricity. It's designed to get your dog's attention, not to hurt it. And after it is trained,
your dog will respond to the audio signal and will rarely experience the shock.
• Electronic containment is a good solution if you are willing to install the wires that form the
system's boundaries, and invest the time necessary to train your dog to respect those boundaries. However,
there are situations in which it may not be appropriate. Electronic containment is not recommended for guard
dogs, vicious dogs or dogs with health problems. Consult your veterinarian if you have any questions about
the suitability of one of these systems for your pet.
• Electronic containment systems are not guaranteed to work for every dog. Some dogs may simply
refuse to respond to the signals from the transmitter. An aggressive dog might be willing to accept the shock if
it's determined to leave the yard. Some systems have come up with solutions to the stubborn dog problem.
There are special collars with stronger corrections and others that emit the corrective shock and/or spray
citronella in front of the dog's face to keep it in place.
Before You Begin
• As with any project, careful planning will make the job much easier. Before you purchase a system,
determine how much area you'll want to cover. Most basic systems include a transmitter with the potential to
enclose an area of about 5 acres. Higher powered transmitters are also available to enclose even larger areas.
Additional wire is necessary for such big jobs. A system will typically come with 1000' of wire, enough to
enclose roughly 1 acre.
• Using graph paper, plot your yard and draw in the area you want to cover. In most cases, corners
must be rounded because right angles confuse the transmitter. The wire forming the fence boundary must
make a continuous loop back to the transmitter.
• Your transmitter must be located indoors in a dry, protected area. A garage is a good choice. Make
sure the transmitter is not located near a breaker box and avoid potential interference problems by installing
the transformer away from appliances such as water heaters or air-conditioning units.
• Most systems recommend that you bury the wires 1" to 3" underground. The wires don't have to be
underground to work, but if they are above ground, it's easy to trip over them or to cut
• them with a lawnmower or trimmer. Test your wires above ground before burying them. You'll
need to determine how close you want your dog to be able to get to the boundary without receiving a warning.
The distance you determine can be adjusted on the indoor transmitter. Some systems will work up to 30 feet
from the boundary and as close as a foot. Just make sure that your dog has room to roam and play without
