Detailed Features

Energy-saving efficiency

The F-789SGA features a practical dual power source. Solar power ensures maximum energy saving, whilst back-up battery power means this calculator never lets you down whatever the light conditions. The ‘auto power-off’ function switches the calculator off when not touched or not in use after 7 minutes, saving even more energy. Also this calculator has a replaceable battery for a long life, typically four years, unlike some calculators that have to be disposed of after single battery use.

High-end scientific calculator

The F-789SGA is the first high-end Textbook Style Display model in Canon’s scientific category. It comes with 605 advanced functions, including 79 built-in constants and 172 patterns of unit conversion. The metallic silver upper case and thin body reflect a professional image. The LCD display measures 60mm by 25mm. As well as students, it is suitable for teachers, engineers and other professionals.

Powerful memory functions

Additional functions include 19 memories, up to 4x4 Matrix calculations and Equation operation – this is one of the most powerful specifications on the market. All of these functions simplify complicated calculations.

Sustainable design

The F-789SGA calculator is part-manufactured from recycled Canon product material to make the top case, bottom case, battery cover and hard case of the calculator. This maximises resource efficiency and minimises wastage.
