- MR (Memory Recall): Recalls the value stored in memory to the display.
- MC (Memory Clear): Clears the memory content.
3.3 Special Functions
- % (Percentage): Used for percentage calculations. For example, to calculate 10% of 200, enter 200 × 10 %.
- √ (Square Root): Calculates the square root of the displayed number.
- GT (Grand Total): Accumulates the results of all calculations performed since the last GT clear. Pressing GT displays the grand total.
- MU (Mark Up): Used for profit margin calculations.
- → (Backspace): Deletes the last digit entered.
- +/- (Sign Change): Changes the sign of the displayed number (positive to negative, or negative to positive).
4. Care and Maintenance
To ensure the longevity and optimal performance of your Catiga CD-2325 calculator, follow these care guidelines:
- Cleaning: Wipe the calculator with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using strong chemicals or solvents.
- Storage: Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Impact: Do not drop the calculator or subject it to strong impacts, as this can damage internal components or the display.
- Liquid Exposure: Keep the calculator away from liquids. If it gets wet, turn it off immediately, remove the battery, and allow it to dry completely before attempting to use it again.
- Battery Replacement: Replace the AAA battery promptly when the display becomes dim or erratic, even in well-lit conditions.
5. Troubleshooting
If you encounter issues with your calculator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim. | Insufficient light for solar power; low battery. | Move to a brighter area or replace the AAA battery. |
| Incorrect calculation results. | Incorrect key input; previous calculation error not cleared. | Press 'AC' to clear all entries and memory, then re-enter the calculation carefully. Use 'C' or 'CE' to clear the last entry if a mistake is made. |
| Keys are unresponsive. | Dust or debris under keys; internal malfunction. | Gently clean around the keys. If the problem persists, ensure the battery is properly installed and charged. |
