need some help with esc..

[Romster]

I got it set-up.
I checked my transmitter Throttle and it was in Reverse mode and I programed it back to Normal throttle. An I got all the beeps. So I put back the red jumpier.
So when I turn on the Esc and press throttle the Esc makes these weired sounds and the motor is not turning.
what should I do..
