Instructions
Push the button on the receiver. A light on the receiver will flash or a sound will be audible, depending on the brand of receiver you have. Soon after, the light will flash or the sound will beep several times. This indicates the receiver̵7;s current level of correction.
Push the button on the receiver and push it again with 5 seconds. The light or sound on the receiver should flash or chime more times than previously. That would be the new, higher level of correction for the collar. Example: Push the button and a light flashes once, followed by two more flashes, indicating a level 2 correction. Push it again within 5 seconds, and it will flash three times indicating an increase to a level 3 correction. After the top correction level, the receiver reverts back to level 1.
Adjust the distance from the boundary wire to trigger a warning alarm. Most transmitter boxes (usually found in the house or garage) have a knob or lever to use to change the distance the receiver's warning beep will first sound. Give the dog an audible warning no less than 2 feet from the wire. The more distance from the wire the alarm begins, the more time the dog has to realize he should turn around to avoid being shocked.
How to Adjust the Shock Level of an Invisible Fence
The shock level of an invisible fence is controlled by the receiver on the dog's collar. Most collars have five or more correction levels: from the lowest which is usually only a warning beep with no shock at all, to the highest for dogs with a high tolerance for correction. If your dog̵7;s receiver has any button on it, whether easily visible or sunken and requiring a pen or pencil to push to operate, the level of correction is adjustable. If not, the receiver will require a technician from the manufacturer to make all changes.
