Introduction
The Kenko KK-82MS-5 is a scientific calculator designed to assist with a wide range of mathematical and scientific calculations. Featuring 240 functions and a 2-line display, it is suitable for students and professionals requiring advanced computational capabilities. This manual provides essential information for setting up, operating, and maintaining your calculator.
Setup
1. Battery Installation
The Kenko KK-82MS-5 calculator typically uses a standard button-cell battery. To install or replace the battery:
- Ensure the calculator is turned off.
- Locate the battery compartment cover on the back of the calculator.
- Use a small screwdriver (if necessary) to open the compartment.
- Insert the new battery, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
Note: The battery is not covered by warranty. Always dispose of used batteries responsibly.
2. Initial Power On
Press the ON button to turn on the calculator. If the display does not appear, check the battery installation.
Operating Instructions
The KK-82MS-5 calculator offers 240 functions. Familiarize yourself with the key layout and the use of the SHIFT and ALPHA keys to access secondary functions printed above the primary keys.
1. Basic Operations
- Arithmetic: Use +, -, ×, ÷ for addition, subtraction, multiplication, and division. Press = for the result.
- Clear Entry/All: Use DEL to delete the last entered digit. Use AC to clear all calculations and memory.
- Replay Function: The REPLAY button allows you to scroll through previous calculations and edit them.
2. Scientific Functions
Access secondary functions by pressing SHIFT followed by the desired key.
- Trigonometry: sin, cos, tan for sine, cosine, and tangent. Use SHIFT + sin (asin), cos (acos), tan (atan) for inverse functions.
- Logarithms & Exponentials: log (base 10), ln (natural log). Use SHIFT + log (10^x), ln (e^x) for exponential functions.
- Fractions: Use the fraction key (often denoted as a b/c or similar) to input and calculate with fractions.
- Powers & Roots: Use x² for squaring, ^ for general powers, and √ for square roots.
3. Memory Functions (9 Memories)
- Store: Press STO followed by a memory variable key (A, B, C, etc.) to store a value.
- Recall: Press RCL followed by a memory variable key to recall a stored value.
- Memory Plus/Minus: Use M+ to add the displayed value to the independent memory, and M- to subtract it.
4. Statistics
To enter Statistics Mode:
- Press MODE and select the STAT mode (refer to your calculator's display for the specific number).
- Input data points, typically by entering a number and pressing M+ or a dedicated data entry key.
- Once data is entered, use the appropriate SHIFT + STAT functions to calculate mean, standard deviation, regression, etc.
Maintenance
- Cleaning: Wipe the calculator with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the calculator in a cool, dry place, away from direct sunlight and extreme temperatures. Use the protector cap to prevent damage to the keys and display.
- Battery Care: If the calculator will not be used for an extended period, it is advisable to remove the battery to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
