How to choose the right length of contact points?
Two series of contact points are supplied with your product.
The length of the contact points must be sufficient to have proper contact with the dog's skin in order to ensure good barking detection and good transmission of the stimulations.
If you have a long-haired dog and the short contact points fitted to the collar in the factory are inadequate, remove and replace them with the long ones supplied with the product.
When changing the contact points, do not use a key to tighten or loosen them; it could damage some components. A moderate manual screwing is sufficient.
