The operation of the blender is very simple. Turn the round button to "on" (must light lights!) Then you have 3 buttons! 1 button (left) "P" when you press, is to mix by suddenly pressing, it mixes, you let go, it stops! / the 2nd button (middle) is to mix the ice, you press 1 once, and he makes his program during a given time / the 3rd button (right) is to make milkshakes or smoothies, you press 1 once he makes his program during a given time! To operate your blender manually, turn the round button to the right and choose the speed yourself, the blender stops to "Off" / Another very important thing (although snap the bowl in the direction of a clock hand until you hear "CLIC" !!! I myself have tried! Well, I'm an individual, like you. hoping that my explanations were clear - Regards and good recipes!
