led circuits in a stepped fashion a constant wait time interval of 120 msec as shown in step 141 is provided between each activation as can be seen upon execution of step 55 all yellow leds y1 y8 are illuminated after a second wait interval step 155 of 400 msec each of the yellow led circuits y1 y8 are sequentially deactivated in ascending numeric order as shown in steps 156 170 a constant wait time interval of 120 msec as shown in step 157 is provided between each deactivation upon executing steps 140 171 to illuminate the leds according to this pattern the microprocessor then compares the number of the current enabled target area with a stored number indicative of the last target in the sequence to determine if the current target area is the last target as shown in module 172 if the current target area is not the last target in the sequence the microprocessor selects the next target area in the sequence to be enabled and initiates execution of the first green pattern for that target area steps 173 174 if the current target area is the last target in the sequence the microprocessor executes the 34 win 34 routine for that target area fig1 shows the routine for illuminating the target area according to the 34 win 34 pattern with flashing red green and yellow leds the steps labeled 176 185 show the sequential activation deactivation of the g1 g4 r1 r4 y1 y8 led circuits in a stepped fashion a constant wait time interval of 50 msec as shown in step 177 is provided between each activation deactivation module the microprocessor continuously executes steps 176 185 until an operator start signal is.
