The manual settings (pulse, low, medium and high) can be used with any of the attachments or in-bowl tools. Attach the food processor bowl to the base unit and add your ingredients, then add the lid. The attachment and lid need to be locked in place for the machine to operate. To do this, ensure that the attachment and lid are aligned, and turn to lock until you hear a click. When correctly assembled all icons will be lit and the screen will display \'00:00\'. If you see four dashes on the screen display, then the attachment or lid are not properly locked in place. Touch the speed name to select the required speed. The machine will start to process the ingredients and the light above the selected speed will begin to flash. To change speed, press the new speed required. To stop the appliance, press the current speed again.
