2. Operating Instructions
2.1 Keypad Layout

Figure 3: Keypad Overview
This image focuses on the main keypad of the Sharp EL-1607R, detailing the arrangement of numeric keys (0-9, 00), arithmetic operators (+, -, x, ÷), percentage (%), memory keys (*M, +M, -M, M+), Grand Total (GT), and clear keys (CE/C).
2.2 Basic Arithmetic Operations
- Addition (+): Enter the first number, press +, enter the second number, press =.
- Subtraction (-): Enter the first number, press -, enter the second number, press =.
- Multiplication (x): Enter the first number, press x, enter the second number, press =.
- Division (÷): Enter the first number, press ÷, enter the second number, press =.
2.3 Memory Functions
The calculator includes independent memory functions:
- M+: Adds the displayed value to memory.
- M-: Subtracts the displayed value from memory.
- *M (Memory Recall/Clear): Press once to recall the memory content. Press twice to clear the memory.
- OM (Memory Clear): Clears the memory content.
2.4 Grand Total (GT)
The GT key accumulates the results of all calculations performed using the = key. Press GT to display the grand total. Pressing GT again clears the grand total memory.
2.5 Percentage Calculations (%)
To calculate percentages, enter the number, press x, enter the percentage value, then press %. For example, to calculate 15% of 200: 200 x 15 % =
2.6 Decimal and Rounding Selectors
Located above the numeric keypad, these sliders control decimal places and rounding behavior.
- Decimal Selector (F, 6, 3, 2, 1, 0, A):
- F (Floating): Decimal point floats automatically.
- 6, 3, 2, 1, 0: Sets the number of decimal places.
- A (Add Mode): Automatically adds a decimal point two places from the right for addition and subtraction.
- Rounding Selector (5/4, Cut, Up):
- 5/4 (Round Up/Down): Rounds up if the next digit is 5 or greater, otherwise rounds down.
- Cut: Truncates the number at the selected decimal place.
- Up: Always rounds up at the selected decimal place.

This image highlights the slider switches for decimal point selection (F, 6, 3, 2, 1, 0, A) and rounding control (5/4, Cut, Up) on the Sharp EL-1607R, located above the main numeric keys.
2.7 Item Count (IC)
The IC switch (often combined with P) enables or disables the item count feature, which tracks the number of entries in a calculation series.
2.8 Clear Entry / Clear All (CE/C)
The CE/C key has dual functionality:
- Press once to clear the last entered number (Clear Entry).
- Press twice to clear the entire calculation and reset the calculator (Clear All).
3. Maintenance
3.1 Cleaning
To maintain the calculator's appearance and functionality:
- Wipe the exterior with a soft, dry cloth.
- For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner.
- Do not use strong solvents or abrasive cleaners.
- Avoid spraying liquids directly onto the calculator.
3.2 Replacing Consumables
Refer to sections 1.2 (Paper Roll Installation) and 1.3 (Ink Roller Installation/Replacement) for detailed instructions on replacing these components.
4. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Calculator does not power on. | No power supply or loose connection. | Ensure the power cord is securely connected to both the calculator and a working electrical outlet. |
| Printing is faint or unclear. | Ink roller needs replacement. | Replace the ink roller as described in section 1.3. |
| Paper does not feed correctly. | Paper roll incorrectly installed or jammed. | Reinstall the paper roll correctly (section 1.2). Check for any paper jams and clear them carefully. |
| Incorrect calculation results. | Incorrect decimal or rounding settings. | Verify the decimal and rounding selector settings (section 2.6). Clear all calculations using CE/C twice. |
