How to set up HoneyGuaridan A36 automatic pet feeder machine?(subtitle included)

We have been used HoneyGuaridan feeder machine for three years. It's really convenient for us. I don't have to worry about my bunnies can't get their pellets on time. And since rabbits always have to eat unlimited hays, I need to control their pellets amount, this machine helps me a lot.
Also, lots of people ask us how to train Jujube to recognize my voice when we are in the park or beach, I have to say because of this feeder machine can record my voice to call Jujube's name. I am not sure if she thoughts food is coming when I am calling her, but she definitely always run back to me no matter where we are.
