Once a unit of angular measurement is set, it remains in effect until a new unit is set. Settings are not
cleared when power is off.
●
You cannot specify the unit of angular measurement (degrees, radians, grads) while the calculator
is in the BASE-N mode. Such specifications can only be made if you first exit the BASE-N mode.
