8-Digit Pocket Calculator
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.
