Troubleshooting

Calculator Not Turning On:

• Check that there is adequate light falling on the solar panel. Solar calculators need sufficient light to power on and function.
• Make sure the calculator is not in direct shade or low-light conditions.
• Check the battery compartment for any loose or improperly inserted batteries if the calculator has a backup battery.

Display Issues:

• If the calculator’s display is dim or difficult to read, ensure that the solar panel is exposed to bright light.
• Clean the calculator’s display and solar panel with a soft, lint-free cloth to remove any dirt or smudges that might affect visibility.
• If the display remains blank or distorted, it could indicate a more serious internal issue, and you may need to contact customer support or the manufacturer.

Calculation Errors:

• Ensure that you are entering numbers and operations correctly. Double-check your input.
• If you are getting incorrect results, it may be due to an order of operations issue. Some calculators use algebraic notation, which means they don’t follow the traditional “PEMDAS” order. Check the user manual for guidance on the calculator’s specific order of operations.

Buttons Not Responding:

• If specific buttons are not responding, check for debris or foreign material lodged under the buttons. Gently clean the keypad using a soft brush or compressed air.
• Ensure that the calculator is not locked or in a mode that disables certain buttons. Consult the user manual for information on locking and unlocking the calculator.

Memory Issues:

• If you are experiencing problems with memory functions (M+, M-, MR, MC), make sure you are using them correctly according to the calculator’s instructions.
• Verify that you are storing and recalling values accurately.

Calculator Freezing or Crashing:

• In some cases, calculators may freeze or become unresponsive. Try turning the calculator off and then on again.
• If the issue persists, consider resetting the calculator to its factory default settings, which can often be done by pressing a combination of buttons specified in the user manual.

Battery Replacement (if applicable):

• If your calculator has a backup battery, and you suspect it is low or depleted, replace it with a fresh battery according to the manufacturer’s instructions.

Contact Customer Support:

• If you have tried all of the above troubleshooting steps and the issue persists, it may indicate a more significant problem with the calculator’s internal components. In this case, contact the manufacturer’s customer support or refer to the warranty for repair or replacement options.
