Usage conditions apply
This handheld electronic scientific calculator has a metal and plastic case and an array of thirty-five rectangular plastic keys. The ten digit keys and decimal point key are white. The keys for total, four arithmetic functions, three trigonometric functions, three inverse trigonometric functions, natural logarithms, exponents, clear, pi, square roots, inverses, and exchange are colored turquoise. The enter exponent, CHN, and four memory keys are orange. A mark behind the keyboard reads: Unisonic 796. The radian/degree and on/off switches are to the right of this. Behind the keyboard is an eight-digit green vacuum fluorescent display. This display also could show a five-digit mantissa and two-digit exponent (with signs for both).
A power jack is on the top edge.
The back of the calculator has a sticker giving calculation examples. It reads in part: 796-A. It also reads in part: SERIAL NO. (/) 002305 (/) MADE IN JAPAN. Below this is a compartment for four AA batteries.
