Casio MS-120EM Blue Desktop Calculator

The Casio MS-120EM Blue is a desktop calculator with a 12-digit tilt display designed for everyday office and home use. It operates on dual power—battery and solar—so it remains functional in varied lighting conditions. The compact form and blue finish provide a tidy, modern appearance while delivering basic arithmetic, percentage, and memory functions commonly required for bookkeeping, invoicing, and general calculations.

Advantages

The dual power system extends operational time and reduces interruptions caused by low light, while the 12-digit tilted display improves readability from a seated position. The layout includes dedicated keys for percentage, memory recall, and a clear key for quick correction of entries. The blue casing resists dirt and complements office decor without excessive bulk, and the overall construction balances durability with a light footprint suitable for a desktop.

Suitable for

• Basic bookkeeping and accounting tasks
• Invoice preparation and price calculations
• Schoolwork and study exercises involving arithmetic
• Retail cash desk support and quick on-the-spot calculations

Key specifications

• Display: 12-digit tilting LCD for improved viewing angle
• Power: Dual power (battery and solar) for reliable operation
• Functions: Basic arithmetic, percentage, memory functions, clear
• Design: Compact desktop format with blue housing
• Keys: Full-size numeric and function keys for tactile input

How to use

Place the calculator on a flat surface and tilt the display to a comfortable viewing angle. Enter numbers and use the arithmetic and function keys to perform calculations; use the percentage key for percent-based computations and the memory keys to store or recall intermediate values. When ambient light is sufficient, the solar cell supplies power; otherwise the battery ensures continuous operation. Replace the battery according to the manufacturer’s guidance when the display dims or performance decreases.

Recommendations

Keep the calculator on a stable, dry surface and avoid prolonged exposure to direct sunlight to preserve the casing color and prevent overheating. Clean the keys with a soft, slightly damp cloth and avoid using strong solvents. Store in a drawer or desk compartment when not in use to reduce dust buildup and extend service life.
