The Flair FC 400 is a grey electronic desktop calculator designed to handle daily tasks in an office, school, or home environment. Its large 12-digit display ensures that long strings of numbers remain clearly visible, while the dual power system combining solar energy and battery backup means you won't be interrupted by a sudden loss of power during your work. This model supports basic arithmetic along with more specialized functions like percentage calculations, square roots, and a grand total feature. To help you manage complex sequences, it includes memory keys for adding and subtracting values (M+, M-) and recalling or clearing them via the MRC button, all while tracking up to 112 calculation steps through its auto replay capability. Measuring 105 x 160 mm, the device fits comfortably on a desk without taking up too much space, making it a practical tool for anyone who needs reliable numerical processing for bookkeeping or study.
