- Sensitive Keys & Durable Sliding Cover: Features responsive buttons for quick and accurate input. The ergonomically designed sliding cover protects the calculator from damage and offers a comfortable grip.
- Battery Powered: Operates on an LR44 battery, ensuring reliable performance even in dim lighting and providing extended service life.
Setup
Battery Installation
The Dexin Scientific Calculator KK-82MS-B is powered by an LR44 battery. To install or replace the battery:
- Locate the battery compartment cover on the back of the calculator.
- Carefully slide or unscrew the cover to open the compartment.
- Insert the LR44 battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
- Replace the battery compartment cover securely.
Note: Ensure the calculator is turned off before replacing the battery. Dispose of used batteries responsibly.
Operating Instructions
Basic Operations
To turn the calculator ON, press the ON button. To turn it OFF, press SHIFT then AC (OFF).
Enter numbers using the numeric keypad. Use the +, -, ×, ÷ buttons for standard arithmetic operations. Press = to display the result.
Scientific Functions
The calculator provides 240 functions. Many functions are accessed by pressing the SHIFT key followed by the desired function key (indicated in yellow above the keys) or the ALPHA key (indicated in red above the keys).
- Trigonometric Functions: Use sin, cos, tan for sine, cosine, and tangent. Press SHIFT then sin⁻¹, cos⁻¹, tan⁻¹ for inverse trigonometric functions.
- Roots and Powers: Use √ for square root, x² for squaring. For n-th roots or powers, use SHIFT with the appropriate function.
- Fractions: Use the ab/c button for fraction input and conversion.
- Logarithms: Use log for common logarithm (base 10) and ln for natural logarithm (base e).
- Angle Modes: To change between Degrees (D), Radians (R), and Gradients (G), press MODE multiple times until the desired mode appears on the display.
- Statistical Calculations: Access statistical modes via the MODE button. Refer to the on-screen indicators for 1-variable and 2-variable statistics.
For detailed instructions on specific functions, please refer to the function labels on the calculator keys and the corresponding secondary functions indicated above them.
Maintenance
Cleaning
To clean your calculator, gently wipe the surface with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the device. Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the display and casing.
Storage and Protection
Always use the durable sliding cover when the calculator is not in use to protect the keys and display from dust, scratches, and impacts. Store the calculator in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity. Avoid dropping the calculator or subjecting it to strong vibrations.
Troubleshooting
If you encounter issues with your Dexin Scientific Calculator, please refer to the following common problems and solutions:
- Calculator does not turn on: Check if the LR44 battery is correctly installed and has sufficient charge. Replace the battery if necessary.
- Display is dim or blank: This may indicate a low battery. Replace the LR44 battery.
- Incorrect results: Ensure you are in the correct angle mode (Degrees, Radians, or Gradients) for trigonometric calculations. Verify your input and the sequence of operations. Clear the calculator's memory by pressing SHIFT then CLR (Clear) and select the appropriate clear option.
- Keys are unresponsive: Ensure no debris is lodged under the keys. Gently press the keys to ensure proper contact. If the issue persists, the calculator may require professional servicing.
If the problem persists after trying these solutions, please contact customer support for further assistance.
