- Description
- This handheld electronic calculator is similar to those of the TI SR-51 family. It has a black plastic case with an array of forty small rectangular plastic keys. In addition to ten digit keys, a decimal point key, and a change sign key (all in white), the calculator has a total key and four arithmetic function keys (all in gold). The remaining keys are brown. One is for on/clear, one is for off, and another, marked "2nd," is pushed to activate the “dual function” indicated on the keyboard above most of the brown keys. The calculator has a variety of statistical, business, and mathematical functions, and limited memory.
- Text above the keys reads: TEXAS INSTRUMENTS (/) TI Business Analyst. Behind this is an eight-digit LED display. The jack for a charger/adapter is on the right side of the calculator.
- Text on the back of the calculator (there is no sticker) reads: TEXAS INSTRUMENTS (/) electronic calculator (/) SERIAL NO. (/) 9818968 LTA4976 (/) ASSEMBLED IN USA. An empty battery pack inside the middle of the back is marked: TEXAS INSTRUMENTS BATTERY PACK BP-7.
- There are no screws to easily take apart the calculator. The device has a black plastic zippered case with a loop.
