press [MODE] followed by the appropriate key.  An M appears on the display
when you press [MODE].

[.]  Enters/exits the Engineering Display mode.  (ENG appears/disappears
     on the display.)  In this mode, calculation results are displayed
     using exponents of 10 that are multiples of 3

[0]  Enters the Unit Calculation mode.  UNIT appears on the display, and
     calculations using seven types of units, such as watts, can be
     carried out.

[1]  Enters Normal Calculation mode.  Pressing [MODE][1] cancels the Unit,
     Base-n, Com[lex, Standard Deviation, or Linear Regression mode.

[2]  Enters Base-n Calculation mode.  Binary/octal/decimal/hexadecimal
     calcualtions or conversions and logical operations can be performed
     in base-2, 8, 10, or 16.

[3]  Enters Complex Calculation mode.  CMPLX appears on the display.

[4]  Sets the angular mode, used for trigonometric calculations, to
     degrees.  D appears on the display.

[5]  Sets the angular mode to radians.  R appears on the display.

[6]  Sets the angular mode to grads.  G appears on the display.

[7]  Sets the display to show a specified number of decimal places.  FIX
     is displayed.

[8]  Sets the display to show the specified number of significant digits.
     SCI is displayed.

[9]  Cancels the FIX or SCI setting.

[+]  Enters Standard Deviation Calculation Mode.  SD is displayed.
