A stylus is placed in the link next to a digit and pulled down to the bottom of the column to enter the digit. Sums appear in seven windows above the chains. There is a clearance knob on the right side and a bent metal piece that can be used to prop up the instrument. The green leather case is stored with the instrument. The stylus is missing.
