Power On/Off

• To turn on: Press the ON key.
• To turn off: Press SHIFT then AC (OFF).

Basic Calculations

Enter numbers using the numeric keypad. Use the +, -, ×, and ÷ keys for standard arithmetic operations. Press = to display the result.

Multi-Function Keys and 2-Line Display

The calculator features a 2-line display, showing both the input expression and the result simultaneously. Many keys have multiple functions, indicated by colored labels above or below them. These functions are accessed using the SHIFT and ALPHA keys.

• SHIFT: Activates the yellow-labeled functions. Press SHIFT, then the desired key.
• ALPHA: Activates the red-labeled functions (variables, constants). Press ALPHA, then the desired key.
• MODE: Changes the calculator's mode (e.g., COMP, STAT, EQN). Press MODE repeatedly to cycle through options.
• CLR: Clears specific data or settings. Press SHIFT then CLR to access clear options.
• DEL: Deletes the character at the cursor position.
• AC: Clears all input and returns to the initial state.

Advanced Functions

The 82Ms-A supports 240 functions, including trigonometric (sin, cos, tan), logarithmic (log, ln), power (x², x³), roots (√, ³√), fractions (a b/c), and statistical calculations. Refer to the specific key labels and their SHIFT/ALPHA functions for detailed usage.

• Trigonometric Functions: Use sin, cos, tan keys. For inverse functions (sin⁻¹, cos⁻¹, tan⁻¹), use SHIFT with these keys.
• Logarithmic Functions: Use log (base 10) and ln (natural logarithm) keys.
• Power and Root Functions: Use x² for squaring, SHIFT then x² for square root (√). For other powers and roots, use x³ or SHIFT then x³ (³√).
• Fractions: Use the a b/c key to input and convert fractions.

Maintenance

Cleaning

To clean the calculator, use a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Do not use strong solvents, alcohol, or abrasive cleaners, as these can damage the casing and display.

Storage

Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the batteries to prevent leakage.
