While you are training the fish I would suggest to set the timer to run several times each morning and afternoon, and for longer than one second. I'd set it to run probably 2-3-4 times for a brief durartion in the morning, maybe every 10 minutes, and the same in the afternoon. This helps train them to associate the sound of the feeder and the feed hitting the water.
As long as you feed them every day, they will learn about the feed and the sound of the feeder...and the sound and sight of your approach and presence. The more often you feed them, the faster they learn. Once you see fish rippling their way 100 feet and more to get to you and the feed you will realize that there isn't much way to actually sneak up on a fish and catch him (litarally) by surprise. In a 10 acre lake they can hear you from any locaion and they always know when you are there in a boat. As the most important fisherman that ever lived, Mr. Buck Perry, said, "When you try to sneak up on a fish....that's when you scare them."
My .02 anyway.
