Unisonic CB-14 Handheld Electronic Calculator

<< >>
This handheld electronic calculator has a metal case with plastic trim and twenty-three rectangular plastic keys. These include ten digit keys, a decimal point key, a total key, four arithmetic function keys, and four memory keys. In addition, the calculator has orange clear and clear entry keys as well as keys for exchange, change sign, square root, squares, and inverses. A mark above the keyboard reads: Unisonic CB-14. Behind this is a nine-digit vacuum fluorescent display.
The jack for a power adapter is on the bottom edge.
The back of the calculator has two clips at the top for attaching it to a leatherette case. It also has a sticker with calculation examples. This reads in part: CB-14. It also reads: SERIAL NO. (/) 179247 (/) MADE IN TAIWAN. At the base is a compartment for three AAA batteries.
The case not only holds the calculator but has space for six credit cards and a pen (this example has no pen).
