Features Your Nexxtech 12-Digit Dual Power Metal Top Desk Calculator can be powered from two different sources, so you can use it almost anywhere. Its built-in solar panel provides power when you expose the calculator to light. When there is not enough light, the supplied battery provides power. Your calculator’s features include: Large 12-Digit Display — makes calculations easy to read. Adjustable Display — tilts forward for easy viewing. Backspace Key — deletes the last number entered. Mark-Up Key — helps you easily determine cost, final price, and profit margin. % Key — simplifies calculation of percentages. Four Function Memory — lets you add to, subtract from, recall subtotals in, and clear all numbers from memory. Automatic Shut-Off — conserves battery power by automatically turning off your calculator about 8–10 minutes after the last entry. Grand Total Key — makes complicated calculations easier. Square Root Key — lets you quickly compute the square root of a number. .. A Look at Your Calculator F 0 2 3 4 A — lets you select how many digits appear after the decimal (see “Setting the Number of Decimal Places” on Page 5). Memory Keys — let you save, add to, and subtract from numbers in memory (see “Memory Calculations” on Page 8). 5/4 — lets you select how calculation results are rounded (see “Rounding” on Page 5). +/– — lets you change a number to positive or negative (see “Using the Special Function Keys” on Page 4). — deletes the last digit entered (see “Using the Special Function Keys” on Page 4). GT (Grand Total) — provides the sum of all memorized numbers (see “Grand Total” on Page 7). MU (Mark-Up) — lets you calculate selling prices and profit margins (see “Mark-Up Calculations” on Page 8). .. Operation TURNING ON THE CALCULATOR Press ON/AC to turn on the calculator. The calculator automatically turns off after about 9 minutes if you do not press any key. Note: The calculator clears all previous entries when it turns off. USING THE SPECIAL FUNCTION KEYS Press +/– to change the displayed number from positive to negative or from negative to positive. Press to delete the last digit entered (for example, when you press the wrong number key). Press 00 to enter two zeros at once. CLEARING ENTRIES To clear an incorrect entry and continue the current calculation, press CE once (0. appears), then enter the correct value and continue your calculation. To clear the display and begin a new calculation, press ON/AC (0. appears), then begin the new calculation. To clear an incorrect operator key (+, –, ., .) entry during a calculation, simply press the correct operator key and continue your calculation. ROUNDING 5/4 .determines how the calculator rounds numbers to the right of a decimal point (depending on the F 0 2 3 4 A setting — see “Setting the Number of Decimal Places”). rounds off the rightmost digit of the calculation result to the next highest number. 5/4 rounds off the rightmost digit of a calculation result to the next hig...
