“Option Settings” is a dialog box, which contains the following: “setting 
list,” a “Confirm” button, and a “Cancel” button. You can move between 
the three items by pressing “tab (“Space-4-5”)” or “shift-tab (“Space-1-
2”)”. The “setting list” consists of “Radian” and “Degree,” in which you 
can move by pressing “Space-1” or “Space-4.” 

If you select “Radian,” you can get the PI value while using the 
trigonometric function. If you select “Degree” and activate PI, you will get 
a wrong answer. You can activate the “Option Settings” if you press 
“Enter” on it, or if you press “o (dots 1-3-5)” in the menu. Of course, you 
can open the menu by pressing “Space-m (dots 1-3-4). Or, in your 
calculation line, you can activate the “Option Settings” by pressing 
“Enter-o (dots 1-3-5).” 

When running the “Option Settings,” if you press “Enter” on what you 
want in the setting list while moving with “Space-1” or “Space-4,” or if 
you press “Enter” on “Confirm” on what you want in the setting list, while 
moving with “tab (“Space-4-5”)”,” you will set the option. 

This is used to exit the calculator. You can quit a calculation if you press 
“Enter” on “Exit Calculator,” or if you press “z” in the menu. Of course, 
you can open the menu by pressing “Space-m (dots 1-3-4). Or, in your 
calculation line, you can exit by pressing “Space-z (dots 1-3-5-6)”. 

The following are examples for each of the math functions that you can 
perform when using the calculator on the Braille Sense U2.
