Casio LC-825 Handheld Electronic Calculator

This compact handheld electronic calculator has an aluminum case with plastic trim and an array of brown plastic keys. In addition to digit keys, a decimal point key, and a total key in a central block, there are four keys for arithmetic functions to the right of the digit keys. A column on the left has percentage, square root, C (clear entry), and AC (all clear) keys. Above these is a power switch and three memory keys. Text behind the keyboard reads: CASIO LC-825 ELECTRONIC CALCULATOR. Text below the keyboard reads: LIQUID CRYSTAL. The eight-digit yellow liquid crystal display is above the keyboard.
A mark on the back reads: BM CASIO LC-875 (/) 1.5Vx2(DC) 0.0003W (/) CASIO COMPUTER CO., LTD. (/) made in Japan. Unscrewing two screws at the base of the back makes it possible to change the two squat batteries. A sticker on the inside back of the case reads: 0642719.
The calculator fits in a brown leatherette case. A mark on the outside of the case reads: CASIO (/) ELECTRONIC CALCULATOR.
The Casio LC-825 was advertised in the Chicago Tribune December 13, 1978, but apparently was not a great success.
