Your KST1000 can be configured for fixed or random start delays in the main menu. With the left and right buttons, you can scroll the fixed start delay. Scroll all the way left to turn off the fixed delay. The random line allows you to add random time to the start delay. Again, scroll right and left to change the maximum randomized time. This combination of fixed and random delay will result in a random delay between 2.0 and 3.0 seconds. To change the lower bound, make the adjustment in the start delay line. To change the upper bound, make the adjustment in the random line.
