Maintenance

1. Cleaning

To clean your calculator, use a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals or solvents, as these can damage the casing or display.

When not in use, store the calculator in its protective hard case to prevent scratches and damage. Keep it away from extreme temperatures, direct sunlight, and high humidity.

3. Battery Replacement

If the display becomes dim or calculations are inconsistent, it may be time to replace the batteries. Refer to the 'Battery Installation' section under Setup for instructions.

Troubleshooting

• Display is blank: Check battery installation. Replace batteries if necessary. Ensure the calculator is turned on by pressing ON/OFF.
• Incorrect calculation results: Verify that all input values are correct. Ensure you are in the correct calculation mode. Clear previous entries using CLR WORK or CLR TVM as appropriate. Reset the calculator if persistent issues occur (refer to the manual for specific reset procedures, usually a small reset button or key combination).
