The pedal has 4 different operating positions, cor-
responding to 4 different rotation speeds:
• Pedal raised (unstable position): slow anticlock-
wise rotation. If the pedal is kept raised for more than
4 seconds, rotation gets faster (always anticlockwise).
• Pedal in the rest position (stable position): turntable stopped.
• Pedal gently pressed downwards (unstable position): slow clockwise rotation.
• Pedal pressed entirely downwards (unstable position): fast clockwise rotation.
