Safety

• Avoid Extreme Temperatures: Do not expose the calculator to extreme temperatures, whether hot or cold. Prolonged exposure to extreme conditions can damage the calculator’s internal components and affect its performance.
• Protect from Direct Sunlight: While the calculator is designed to harness solar power, prolonged exposure to direct sunlight may cause overheating and damage the unit. Store it in a shaded area when not in use.
• Prevent Moisture Exposure: Keep the calculator away from moisture, water, and liquids. Moisture can corrode the internal circuitry and lead to malfunctions.
• Proper Battery Use: If you are using AAA batteries as a backup power source, insert them correctly following the polarity markings inside the battery compartment. Use high-quality, fresh batteries, and replace them when depleted. Dispose of old batteries in accordance with local regulations.
• Avoid Dropping or Impact: Handle the calculator with care and avoid dropping it or subjecting it to impact. Physical damage can harm the calculator’s components and affect its accuracy.
• Keep Away from Dust and Debris: Dust and debris can accumulate over time and affect the functionality of the calculator. Clean the calculator’s surface and solar panel with a soft, dry cloth regularly to prevent dust buildup.
• Do Not Disassemble: Do not attempt to disassemble the calculator yourself. Disassembling the unit can void the warranty and may lead to damage. If there are issues that require internal inspection or repair, contact the manufacturer or authorized service centers.
• Proper Storage: When not in use, store the calculator in a clean and dry location, away from direct sunlight and extreme temperatures. Use the protective cover or case if provided to prevent scratches or damage.
• Keep Out of Reach of Children: Ensure that the calculator is stored out of the reach of children to prevent any misuse or accidental damage.
• Read the User Manual: Familiarize yourself with the user manual provided with the calculator. It contains important information about usage, maintenance, and safety guidelines specific to your model.

Maintenance

1. Cleaning: Regular cleaning helps maintain the appearance and functionality of your calculator. Here’s how to do it:
   • Use a soft, dry cloth to wipe the calculator’s surface. Avoid abrasive materials that could scratch the display or buttons.
   • In case of stubborn stains or dirt, lightly dampen the cloth with water or a mild cleaning solution and wipe gently. Ensure that no liquid enters the calculator’s openings.
2. Battery Replacement: If you’re using the AAA battery backup, you will need to replace the batteries as they deplete. To do this:
   • Turn off the calculator.
   • Open the battery compartment on the back of the calculator.
   • Replace the old AAA batteries with new ones, following the correct polarity (usually indicated in the compartment).
   • Close the battery compartment securely.
3. Solar Panel Care: The calculator’s solar panel is essential for charging the internal rechargeable battery and powering the device. To maintain its efficiency:
   • Keep the solar panel clean and free from dust, dirt, or obstructions. A dirty solar panel may reduce its ability to charge the battery effectively.
   • Ensure the panel is exposed to adequate light. Place it in well-lit areas or near a light source when not in use to maintain the charge.
4. Protecting from Extreme Conditions: To ensure the longevity of your calculator, protect it from extreme environmental conditions:
   • Avoid exposing the calculator to direct sunlight for extended periods, as this can potentially damage the display or the solar panel.
   • Keep the calculator away from extreme temperatures, as excessive heat or cold can negatively affect the device’s performance.

Troubleshooting

• Calculator Won’t Turn On: If you’re using batteries as a power source, make sure they are properly inserted, and they are not depleted. Replace the batteries if necessary. Ensure the calculator is exposed to sufficient light. It may take a moment to power on when switching from battery to solar power, especially if the batteries were previously depleted.
• Display is Dim or Flickering: If using solar power, ensure the calculator is exposed to bright, direct light. A dim display may be due to inadequate light conditions.
• Erroneous Calculations: Double-check your input to ensure you haven’t made any mistakes in your calculations. If you’ve used the memory functions (M+, MR), make sure you’ve cleared them or are using the correct stored values.
• Auto Power-Off is Too Quick: The calculator has an auto power-off feature to save energy. If it turns off too quickly, check the user manual for instructions on adjusting the auto power-off settings, if available.
• Unit Conversion Errors: Ensure you’ve selected the correct conversion mode and units. Refer to the user manual for guidance on unit conversion.
• Display is Not Clear: Clean the calculator’s display with a soft, dry cloth to remove any smudges or dust that might be obstructing the screen.
• Buttons Not Responding: Make sure the buttons are not obstructed or jammed. Clean around the buttons, and try pressing them with adequate force.
• Unresponsive Calculator: If the calculator becomes entirely unresponsive, attempt a reset if it’s a feature described in the user manual. If not, contact SamFansar customer support for further assistance.
• Errors Persist: If problems continue after trying the above steps, consult the user manual for more specific troubleshooting guidance.
