Hi
It's relatively easy to set. With your transmitter radio turned off all you have to do is press and hold the program button on the ESC's on & off switch when you turn the ESC to ON. When the ESC beeps let go of the program button and you will then hear one more beep . By default you are now ready to select the Battery Mode options. To do that press and hold the program button, you will here one long beep followed by 1, 2, or 3 sort beeps. If you hear only one beep Lipo mode is selected, if you hear 2 beeps NiMh mode is selected, if you hear 3 beeps No Cut-off (5v Min) mode is selected. If the ESC is on a setting that you do not want then all you have to do is push the program button, don't hold just push and it will cycle to the next option in the list, and when your at the option that you want to use all you have to do is press and hold the program button. After you have selected and set the option that you want to use the ESC automatically moves to the next category which would be Running Mode. You can also cycle threw each of the category's by just pushing the program button, don't hold just push and it will cycle to the next category. There are 6 category's, and there will be 1 beep for category 1, 2 beeps for category 2, and so on up to category 6. And to select a category all you have to do it press and hold the program button to enter that category. And if you want to exit the program mode just turn the ESC Off. Hi hope this helps you.
