Note
The initial default calculation mode is the COMP Mode.
Mode indicators appear in the upper part of the display, except for the BASE indicators, which appear in the exponent part of the display.
Engineering symbols are automatically turned off while the calculator is the BASE Mode.
You cannot make changes to the angle unit or other display format (Disp) settings while the calculator is in the BASE Mode.
The COMP, CMPLX, SD, and REG Modes can be used in combination with the angle unit settings.
Be sure to check the current calculation mode (SD, REG, COMP, CMPLX) and angle unit setting (Deg, Rad, Gra) before beginning a calculation.
