This humane and safe product was developed by veterinary technicians.

Mounting locations:
The best place to locate the Bark Free system is slightly above and facing the dogs. The Bark Free will detect barking up to 25 feet away, so mount the unit for dogs within the 25 feet. Be sure that your dogs cannot reach the unit, they may chew it up. Also be sure that extension cords are not within their reach. The Bark Free can be mounted or placed free standing in a desirable location. If using indoors, place Bark Free in a room where the dog is often known to bark. Note: If you place the unit in a room and your dog is in another room, Bark Free can be effective but results may not be as significant.
Bark Free is weather resistant, but not waterproof. It comes with a vinyl cover to protect against rain, sprinkler systems, and other sources of water. Direct expo¬sure to water will temporarily reduce the sensitivity of the microphone and speak¬ers. Outdoors, Bark Free may be triggered by loud sounds other than barking. Try to avoid mounting in damp and high wind areas. If water enters the unit through the speaker holes, lay the unit down to allow water to drain out. If the unit stops working when wet, it will resume operation when dry. Controls can be used without removing the vinyl raincoat. This clear cover is resistant to heat, cold, and ultravio¬let light. The bracket includes mounting slots and screws for fastening unit to a tree or post.

Bark Pick-Up Sensitivity Adjustments:
This adjustment allows you to control how loud the bark must be to trigger the cor¬rection tone, while eliminating any false triggering. Make this adjustment on a calm day if the system is mounted outdoors. To adjust the sensitivity, first set the audible sound selector (located above the sensitivity switch) to audible. This lowers the correction tone frequency, so that you hear the tone. Move away from the unit and listen. If you do not hear the tone each time you hear barking, adjust to the higher sensitivity level or move the unit closer to the dog. If you hear the tone without hearing the barking, adjust to the lower sensitivity level. Larger dogs react better to lower tones while smaller dogs have a better reaction to higher tones. When you have the sensitivity adjusted, reset the switch to “ultrasonic” (if desired). Use the lowest possible sensitivity setting that will respond consistently to barking. If it is set to high other sounds, may trigger the unit. The “Novel Stimulus” aspect of the tone will then be lost and your dogs will learn to ignore Bark Free. Also be sure that the background noise level is not to high or it will cause continued triggering. You can correct this by reducing the sensitivity level.
Note: Do not try to instigate barking from your dog to find out if Bark Free will stop them from barking. A dog will always bark if harassed. Test Button:
Pushing the test button will lower the ultrasonic frequencies to an audible human level. This way you can hear the different ultrasonic features. To avoid hearing damage, do not use the Test button for long periods of time and do not allow chil¬dren to play with the test switch.

Power:
The Bark Free is powered by a 12V center pin (+) DC adapter, included. Use the 50’ extension cord if needed, also included. Note: The transformer case is not weather resistant and must be plugged indoors if not using a weather resistant outdoor case. A protected casing is available at your local hardware store.
