The first number depicts the cycles, the second number how many flares will be ejected each cycle and the last number is the time in seconds between cycles.
There are 2 notable exceptions though. if the first digit is set to 5 or 7 the actual cycle quantity is 12 resp. 15. 0 equals continuous release.
And if the third digit is 7, 9 or 0 the actual time between releases is 0.25; 0,5; 0,125 seconds.
The program, i.e. the three digits, only help the pilot to reduce his attention needed for the release of flares in a preprogrammed fashion.
The system is solely programmed through the pilot's input, it's not linked with the laser warning receiver.
