Dogtra T & B (Train & Beep): In "Run" mode the T & B beeps every five seconds when the dog is running and every two seconds when the dog is on point. In "Point" mode, the collar gives a double beep every two seconds when the dog is on point. If you wish to control when it beeps, use the "Locate" button and this collar will only beep when you press the button. Then it will beep for as long as you hold the button down. The beeper function is selected with a slide switch on the side of the transmitter. After selecting the beeper mode, just move the slide switch to "stimulate" and the collar will "beep" plus work like a Dogtra 500 with "nick" and "constant" stimulation.
