Options: Pause Control
How you operate the Roberta, there are three controls on all models: on/off, forward/reverse and a speed control knob. For spinning you would normally set the wheel to forward and then turn it on. You will adjust the speed as you begin spinning to achieve the yarn twist you require. For the remainder of the time you are spinning, there will be no need to adjust the speed. To stop spinning, you turn the wheel off.
If you have the optional Pause Control, it works in the following manner: it acts as an on/off switch only. It is set to the "on" position all the time, meaning your wheel is operating. If you want to temporarily turn your wheel off, just push the switch with your foot and hold it. When you remove your foot, the wheel begins to spin again. Such a switch allows you to start and stop spinning without having to use your hand or the on/off switch that is on the wheel. This switch is not a speed control. When you have finished spinning, you must turn off the wheel using the switch on the wheel.
