My Transmitter Has Red and Black Buttons, How Do They Work?
The red button is for continuous stimulation. If the remote trainer has two red buttons, they deliver continuous stimulation at different levels, with the bottom being the lowest, the upper the next level (medium), and both buttons together the third level (high). All continuous settings have a safety timeout feature, the length of which varies by model. The black button delivers momentary stimulation. If the remote trainer has one red button and two black buttons, then the two black buttons deliver momentary stimulation at different levels, with the bottom being the lowest, the upper the next level (medium), and both buttons together the third level (high).
