How the Shock-Free No-Bark Ball with Dual Sonic Technology works
Motorola's No-Bark Ball is a quick, easy and fair way to reduce excessive barking
behavior. Whenever the No-Bark Ball detects that your dog is barking, it releases
an unpleasant high-pitched ultrasonic sound to interrupt its barking.
You can choose from three levels of correction (Level 1 - low ultrasonic sound,
Level 2 - medium ultrasonic sound, Level 3 - high ultrasonic sound) to match
your dog's personality. Our goal is to limit excessive barking, not to attempt to
eliminate or suppress all barking.
Important guidelines when using the Shock-Free No-Bark Ball with
Dual Sonic Technology
• Even though most humans cannot hear the ultrasonic sound, do not place
the No-Bark Ball close to the ear.
• Do not allow children to operate the system.
• All pets within the hearing range will be affected by the ultrasonic sound.
• Do not drop the No-Bark Ball.
• The No-Bark Ball is designed for use with dogs to control excessive barking
behavior only. Do not use it for any other purposes that are not described in
this User's Guide.
• For best results, use indoors.
