Operating Instructions

1. Basic Operations (Adding Machine Logic)

The CATIGA CP90A operates as an adding machine, which differs from a standard calculator. All operations are treated as additions to a running total. Subtraction is performed by adding a negative number.

• Addition: Enter the first number, press [+]. Enter the second number, press [+]. The display shows the running total.
• Subtraction: Enter the first number, press [+]. Enter the number to subtract, press [-]. The display shows the running total.
• Subtotal: Press [*] to display and print the subtotal without clearing the running total.
• Grand Total: Press [GT] to display and print the final total and clear the memory.

• Date & Time: Press the [Date/Time] button to print the current date and time on the tape. Refer to the full manual for setting the date and time.
• Rounding Switch: Adjusts how calculations are rounded (e.g., up, down, or 5/4 rounding).
• Decimal Switch: Sets the number of decimal places for calculations.
• Backspace Memory: Corrects the last entered digit.
• Percent Key: Performs percentage calculations.
• Key Memory: Stores and recalls values from memory. Use [M+] to add to memory, [M-] to subtract from memory, [M*] to recall memory, and [M0] to clear memory.
