17.1 Calculator
Using the calculator on the Braille Sense OnHand you can do simple
math equations as well as complex scientific calculations. The results
and formulas will be displayed in Braille, and spoken by the Braille
Sense OnHand. While using the calculator, you can refer to the “help”
menu by pressing “Space-h (dots 1-2-5)”. The “help” menu is very
useful as you can quickly access hot key information for the various
programs on the Braille Sense OnHand.
When you want to use the calculator you can press “c (dots 1-4)” from
within the “Utilities” menu. When using the calculator on the Braille
Sense OnHand, you need to type using computer Braille when
calculating or inserting your formulas. You can initialize your
calculation line by pressing “Backspace-c (dots 1-4)”. If you insert
numbers or a function into a result, the result will disappear; and if you
put in operators, you can get to the next step. In addition, you can keep
your result in the calculator’s memory, and you can recall it when you
need the result. You can use the function and operators via the
calculator menu or you can use the hot keys depending on which
method works best for you.
