Fitting the Collar
Proper collar fit is crucial for effective and safe operation. Position the collar high up on your dog's neck, close to their head, ensuring the receiver box is directly beneath the chin. Avoid placing the collar on the broader part of the neck, as it may loosen during movement.
Adjust the collar so that you can comfortably slide two fingers between the collar and your dog's neck. The fit should be snug enough to ensure consistent skin contact with the electrodes without restricting breathing.

WARNING: Do not cut the part of the Collar Belt that has the embedded antenna. Doing so will damage the antenna and may result in decreased Collar Receiver range.
