HOW THE SYSTEM WORKS
The Pet Containment System consists of three primary components: FENCE TRANSMITTER,
RECEIVER, and BOUNDARY WIRE (antenna).
Fence Transmitter
The Fence Transmitter has been designed to operate with a boundary wire up to 4000 feet or 25 acres,
and plugs into any standard outlet. The transmitter produces a very low frequency radio signal. The
magnetic field it generates is carried by the boundary wire which serves as an antenna. The range or
width of the magnetic field (i.e. the distance from the boundary wire to activate the receiver) can be
adjusted from a few feet up to thirty feet by the boundary width control knob located on the transmitter.
Receiver with Collar
The UL-250 Receiver contains electronics to detect the magnetic fi eld carried by the containment
boundary wire, translates them, and delivers a static correction. The static correction is delivered
through two contact points that touch the dog’s neck.
There are two sets of contact points that can be used on your receiver. The longer contact points
should be used on dogs with long hair.
The UL-250 Receiver is enclosed in a waterproof case and is mounted on a polypropylene collar. The
collar will fi t a dog with a neck size varying from 9 to 22 inches.
Laying out the System
Basic Planning Tips:
• The boundary wire must make a continuous loop back to the transmitter.
• Make a layout that is suitable for your yard. Sample layouts are provided.
• Always round the corners of your boundary with the wire. Sharp corners will distort the signal.
• Use a double loop layout to contain your pet on one side of your home. Ref: Fence front yard
only below.
• When installing a double loop, the wire must be spaced three to five feet apart to avoid canceling
the signal.
• The transmitter will transmit a signal from approximately two to thirty feet on either side of the
boundary wire. Be sure to leave enough area so that your dog can move about freely within the
safe area boundaries.
