If you choose Degrees, all arguments of the trigonometric functions will be considered to be in degrees and the inverse trigonometric functions will give results expressed in degrees.
If you choose Radians, all arguments of the trigonometric functions will be considered as being in radians and the inverse trigonometric functions will give results expressed in radians.
If you choose Gradians, all arguments of the trigonometric functions will be considered to be in gradians and the inverse trigonometric functions will give results expressed in gradians.
The unit of angles is displayed in the top banner of the screen as deg, rad or gon.
If you choose Decimal, the numerical values will be displayed according to calculator presets so that they are as appropriate as possible for each application.
If you choose Scientific, the numerical values will be displayed in scientific form. A sci indicator then appears in the top banner of the screen to indicate that your results are displayed in scientific notation.
If you choose Engineering, the numerical values will be displayed in engineering form. An eng indicator then appears in the top banner of the screen to indicate that your results are displayed in engineering notation.
You can choose the number of digits to display for the results by directly modifying the value in the section Significant figures. The maximum number of digits that can be displayed is 14.
You may choose the editing mode of mathematical expressions: in one line (linear) or in two dimensions (natural).
If you choose Real, complex results will not be displayed.
If you choose , complex results will be displayed in rectangular form.
If you choose , complex results will be displayed in polar form. In this case, the argument in the exponential will always be given in radians, even if the angle unit is set to Degrees.

A message appears indicating that the activation of the exam mode will erase the data. Choose Confirm and press ok.
You are now in test mode.
Enabling the test mode deletes all recorded data: calculation history, variables, function list, statistical series, Python scripts, etc.
When the test mode is active, the selected features will be disabled and a symbol appears in the yellow band at the top of the screen.
You may only exit the test mode by connecting the calculator to a computer via a USB cable. As soon as you connect the machine, a message will appear that prompts you to exit exam mode. Highlight Confirm and press the ok key.
