65-500 OWNER’S MANUAL — Please read before using this equipment.
Thank you for purchasing the RadioShack Translucent Calculator 3-Pk. Its compact size lets
you conveniently use it to perform calculations almost anywhere. There are three calculators,
so you can leave one at home, one at the office, or any place else.

the display when:
• A calculation result exceeds eight digits
(overflow error). See “Estimating
Calculation Results”.
• A memory calculation result exceeds
eight digits to the left of the decimal
point. The memory contents remain
unchanged.
• You try to divide by 0.
• You try to calculate the square root of a
negative number.

If you perform a calculation that results in an
overflow error, follow these steps to estimate
the correct result to eight significant digits.
1. Count the number of digits to the left of
the decimal point.
2. Remove the decimal point.
3. Add as many zeros to the right of the
number as there were digits to the left of
the decimal point. For example, if
;HHEHý ;HHEHý ;HHEHý ;HHEHý
'$&'*(&,* '$&'*(&,* '$&'*(&,* '$&'*(&,*
appears, the approximate
answer is 101,420,640. If ;HHEHý ;HHEHý ;HHEHý ;HHEHý

answer is 31,970,347,000.

Operation
If you do not press a key for about five to ten
minutes, the calculator automatically turns off
and you lose any pending calculation.
Care
Keep the calculators dry; if they get wet, wipe
them dry immediately. Use and store the
calculators only in normal temperature
environments. Handle the calculators carefully;
do not drop them. Keep the calculators away
from dust and dirt, and wipe them with a damp
cloth occasionally to keep them looking new.
If your calculators are not performing as they
should, take them to your local RadioShack
store for assistance. Modifying or tampering with
the calculator’s internal components can cause
a malfunction and might invalidate their
warranty.
