Angular Measurement Units
You can confi gure the angular measurement units (degrees,
radians, gradients) by pressing the button followed by
the 4, 5, or 6 buttons. Afterwards press the button.
The values 4, 5, and 6 represent degrees, radians, and gra-
dients respectively.
Once the angular measurement unit has been confi gured,
the confi guration will remain until it is manually changed.
This confi guration will be saved even if the calculator is
powered off.
When the calculator is in Base-N mode, you will not be able
to adjust the angular measurement unit.
