Right of the keyboard are square keys (and an addition bar) marked with a star (for totaling), an S (for subtotals), a subtraction sign, an addition sign, and a “#” (for non-add). The machine prints these symbols, except in the case of addition. Subtracted numbers are in red. There also is a repeat lever. Behind the keyboard and the dials to the left is a lever controlling the printing mechanism. This mechanism and the narrow paper tape, fixed carriage, and motor are at the back. There appear to be 11 keys in the printing mechanism.
