Game Feeders

I have a question that I hope some one can help me with. I was given a Kenco tornado wild life feeder that was brand new but the instructions were lost. Does any one know how to program one of these. My understanding is that you can program for feeding times and possibly patterns. The unit I have has a photo cell and there is a test button along with a chip board. I had some one tell me that the programming was determined by how many times you pushed the test button. Any Idea's would be greatly appreciated.

Hold the test button down for as long as you want each of the three motors to throw feed. ie, holding it down for 5 seconds will throw feed for 5 seconds from the first motor, the 5 seconds for the second, etc.............total of 15 seconds will be thrown. You cannot program the throw times. The photoelectric eye will turn it on at dawn and dusk.
