• You may need to trim the hair in the area of the
Contact Points. Never shave the dog’s neck;
this may lead to a rash or infection.
• Always remove your dog’s Receiver Collar
before performing any Transmitter testing.
• The Receiver Collar should not be on your
dog when the system is tested. Your pet may
receive an unintended correction.
• The Boundary Width of the system must be
tested whenever an adjustment is made to
the containment field to prevent unintended
corrections to your pet.
• If you use a collar and leash for training, be
sure the extra collar does not put pressure on
the contact points.
