FEATURES

Your 8-Digit Pocket Calculator is small, yet it has the features you use the most. It includes the four basic math functions (addition, subtraction, multiplication, and division), plus it has percentage, square root, and memory functions. Its other features include:

Dual Power — the solar cell powers the calculator when there is enough light, and the replaceable battery powers the calculator when the light is dim.

Large 8-Digit Liquid Crystal Display —makes it easy to read calculation results.

Automatic Power Off — conserves battery power by turning off your calculator if you do not press a key for about 7 minutes.

ERRORS

Your calculator displays ERROR and does not allow fur- ther calculations if you:

•try to take the square root of a negative number.

•try to divide by zero.

•perform a calculation that results in an answer greater than 99,999,999.

In this case, you can determine the approximate answer by counting the number of digits displayed to the left of the decimal point, putting that many zeros on the right side of the number, then deleting the dec- imal point.

For example, if the calculator displays ERROR 3423.8381, the approximate answer is 342,383,810,000. To clear the error and continue the calculation with the displayed number, press CE.

To clear the entire calculation, press ON/C.

5 ⋅ 5 ⋅ 5 ⋅ 5 + 2 + 2 = 629	5 x = = = + 2 = =	629.

+/– — Press to change the displayed num-

ber from positive (+) to negative (–) or from negative (–) to positive (+). MINUS– ap- pears when the value is negative.

For addition, subtraction, and division, the value you enter before pressing = is the constant. For multiplication, the value you enter before pressing ⋅ is the constant.

Memory Calculations

Note: If you press an incorrect operator key (+, –, ⋅, or ÷), simply press the correct one and continue with your calcu- lation.

To store a value in memory, first press (memory recall/ clear) twice to clear the memory, then press ON/C to clear all calculations.
