GETTING STARTED
1. Check the Current Calculation Mode
Be sure to check the status indicators that indicate the
current calculation mode (DEG, BIN, STAT and CPLX)
and display formats setting (Floating mode).
Note! If you get into trouble, hold + to reset
the calculator.
2. Key Symbols
The "D" key is colored in gray.
To use a function printed above a key in gray,
