Setup

1. Unpacking and Inspection

This adding machine uses thermal paper, eliminating the need for ink cartridges.

1. Open the paper roll cover located at the top rear of the machine.
2. Place the new thermal paper roll into the compartment, ensuring the paper feeds from the bottom of the roll.
3. Pull a small length of paper out and feed it through the printer slot until it emerges from the front.
4. Close the paper roll cover. The machine features an easy-to-load paper mechanism for convenience.

Operating Instructions

Understanding the Adding Machine Logic

The CATIGA SP-2401 is an adding machine, not a standard algebraic calculator. This means operations are entered differently, and the machine maintains a running total.

Figure 3: Visual Explanation of Adding Machine Operations

• Addition: To calculate 4 + 2 = 6, enter 4 + 2 +. Then press the * (Subtotal) key to display and print the subtotal. The machine adds each entry to a running total.
• Subtraction: To calculate 4 - 2 = 2, enter 4 + 2 -. Then press the * (Subtotal) key. (This treats the operation as 4 plus negative 2).
• The * key acts as a Subtotal function. It displays and prints the current subtotal without finalizing or clearing the grand total.
• The GT (Grand Total) key will display and print the final accumulated total and clear the machine for a new calculation series.
