speed controller problems
 

hey guys!
I recently bought my first programable speed controller after a recommendation.
It is the expert ComPro TMM 4016-3s HELI.

Once we turn the transmitter on with the throttle on max, and then turn the speed controller on (as per the manual), the controller beeps and flashes constantly at a constant rate. This is the first error in the manual but the trouble-shooting is hopeless! It says to shorten or lengthen the throttle throw (which we have done and doesnt help) or that there is a current overload.

Has anyone had similar problems and would know how to fix it?

Thanks!
