Clamp it into position if you dont have any im-mediate plans to play records.O PLATTER/RUBBER PLATTER MATWhen the tonearm is moved and power is supplied to

21、 theturntable, the platter will start rotating at the set rotationspeed. The rubber platter mat stabilizes the records andalso absorbs external vibration.
