Setting new standards in hygiene
Hygiene in schools and colleges is a vitally important issue. Now Canon?s anti-bacterial scientific calculator helps eliminate potential health care problems, thanks to an approved inorganic antimicrobial agent* applied to the plastic key tops. This reduces the growth of bacteria that can build up on calculator keys ? especially in active school surroundings. This makes the F-789SGA an excellent choice for Primary, High School and University student use.
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.
