Introduction
Thank you for purchasing the Graphic Scientific
Calculation.
This unit is a totally new type of advanced programmable
calculator. Besides versatile scientific functions, graph
functions also make it possible to produce a wide variety of
useful graphs.
Manual calculations can be easily performed following
written formulas (true algebraic logic). A replay function is
provided that allows confirmation or correction when key
operation errors occur. Programs can also be input by
following true algebraic logic, so repeat and/or complex
calculations are simplified.
All of this power built into a compact configuration that folds
up to slip right into your pocket.
Be sure to carefully read this manual and keep it handy for
future reference.
Important–Reset your calculator before using it for the
first time!––––––––––––––
Important––Always back up data!––––––
This product features electronic memory that is capable of
storing large volumes of data. You must also remember
