- Additional functions:
- ---------------------
- Press <F1> function key to display a help window.

-
- The line above the display is the Status Line.
- The Status Line contains the information about the current mode of the
- calculator :
- - BINary, HEXadecimal, or DECimal mode of display ;
- - DEGree or RADian mode for trigonometric functions ;
- - °Celsius or °Fahrenheit mode ;
- - ( - number of open brackets entered ;
- - ) - number of close brackets entered.
-
- History window displays a list of intermediate results and operators used.
-
