Calculadora de secretária Casio DE-12E-WE básica 12 dígitos branca

The Casio DE-12E-WE is a basic 12-digit desktop calculator in white, designed for everyday personal and professional use. It provides essential functions such as currency conversion, tax calculation and profit calculation, and uses dual power (solar with battery backup) for reliable operation. The calculator features an extra-large display and an ergonomic key layout developed to match natural finger movements and improve typing comfort.

Advantages

The DE-12E-WE offers an extra-large display that makes numbers easier to read and durable anti-fade keys produced by two-colour injection molding so markings do not wear off. Ergonomic step keys and specially shaped key caps follow the contours of the finger for more comfortable input. Large rubber feet prevent slipping during use. A display symbol shows the current arithmetic operation, and silent touch keys reduce noise. Three-key rollover stores key operations in a buffer to prevent missed inputs during fast entry. Dual power (solar and battery) ensures operation in different lighting conditions.

Suitable for

• Everyday desktop calculations at home or office
• Small business tasks: tax, profit and currency calculations
• Situations requiring clear numeric display and frequent input

How to use

Place the calculator on a stable, flat surface and ensure sufficient light for solar operation; the battery will supply power when light is insufficient. Use the ergonomically shaped keys for numeric input and standard arithmetic functions. Use the dedicated keys for tax, currency conversion and profit calculations as required; consult the printed markings on the keys and the included quick guide for specific key sequences. Check the display for the function command sign (+, −, ×, ÷) that indicates the current operation.

Recommendations

To preserve key markings and ensure long life, avoid exposing the calculator to extreme temperatures or direct sunlight for extended periods and store it on a flat surface when not in use. Clean the surface and keys with a dry or slightly damp cloth; do not use strong solvents.
