Function Description
The Canon MP41DHII is a printing calculator designed for various arithmetic operations, including addition, subtraction, multiplication, and division. It features specialized functions for business and financial calculations.
Key Functions:
- Decimal Point Selector Switch: Allows users to designate the decimal point position for calculated results. Options include floating decimal point (F), add-mode (+), and fixed decimal positions (0, 2, 3, 4, 6).
- F (Floating Decimal Point): Prints or displays all effective numbers up to 14 digits.
- + (Add-Mode): Performs addition and subtraction with an automatic 2-digit decimal, convenient for currency calculations.
- Rounding Switch: Used for rounding up (↑), round-off (5/4), or round-down (↓) to the pre-selected decimal digits in the result.
- Grand Total / Rate Set Switch:
- Grand Total (GT): Accumulates totals in the grand total memory. Pressing
☑ prints subtotal with "GT+", GT prints intermediate grand total with "G◇", and successive presses of GT print the grand total with "GЖ".
- Rate Set: Sets or recalls the TAX rate.
- Item Count Switch (ITEM): Counts and prints the number of calculation items up to 999.
- "n+" position: Counts the number of times
+ and – keys are pressed.
- "n+/–" position: Counts
+ key presses and subtracts – key presses.
- Memory Item Count: In "n+" position, counts
M+ and M- key presses. In "n+/–" position, counts M+ key presses and subtracts M- key presses.
- Print Out of Item Count: When PRINT switch is "ON" and ITEM switch is "n+" or "n+/–", the number of items (up to three digits) can be printed on the left side of the paper by pressing
☑ or ☑ for item count, and M+ or M- for memory item count.
- Power / Print Switch:
- POWER OFF: Turns power off.
- POWER ON / PRINT OFF: Turns power on; entries and results appear on the display but are not printed.
- POWER ON / PRINT ON: Entries and results appear on the display and are printed.
- Tax Calculation Function:
- TAX+: Adds the tax amount to the displayed figure.
- TAX-: Deducts the tax amount from the displayed figure.
- The entered tax rate remains stored even when the calculator is turned off, but is deleted if the plug is disconnected.
- Cost-Sell-Margin Calculation Function: Calculates cost, selling price, and profit margin. Users enter values for any two items to obtain the balance value.

- Non-Add / Subtotal (#): Prints information (dates, serial numbers) that does not affect calculations on the left side of the paper. Also obtains intermediate results.
- Total (☑): Obtains addition and subtraction results.
Overflow Function:
- Indicated by "E" on the display, a dotted line printed, and locked keyboard.
- Occurs when:

Maintenance Features
General Maintenance:
- Environment: Do not use or leave the calculator in direct sunlight. Avoid areas with rapid temperature changes, high humidity, dust, and dirt.
- Cleaning: Use a dry cloth to clean the casing. Do not use water or detergents.
