Sanyo ICC-807D Handheld Electronic Calculator

Description
This hefty handheld electronic calculator has a metal case and eighteen indented square plastic keys. These include ten digit keys, a decimal point key, four arithmetic function keys, a clear display key (CK), a clear all key (CA), and an arrow key pushed to show digits not indicated on the display (the display shows eight digits in the result, but calculations are to sixteen digits). The addition and subtraction keys also serve as total /difference keys.
The keyboard also has a switch that may be set at 0, 2, or 4 to indicate the placement of the decimal point. A mark below it reads: DECIMAL P. Behind the keyboard is a light that indicates when the battery is low. A tag next to it reads: SANYO. Behind this is the eight-digit gas discharge display. An on/off switch is on the right side and a jack for a power adapter at the back edge.
A tag on the back of the calculator reads: SANYO MODEL ICC-807D (/) ELECTRONIC CALCULATOR (/) INPUT DC 7.5 V (/) DC 7.5V, DC 2.5W (/) SERIAL NO. 77123492 T (/) SANYO ELECTRIC CO., LTD. MADE IN JAPAN.
