ADDITIONAL INFORMATION
Accuracy/Display – Your calculator has
an eight digit display. In a standard cal-
culation, each calculation is carried out
internally to ten digits and is rounded
to an eight digit value. A 5/4 rounding
technique is used to add one to the
least significant digit in the display if
the next non-displayed digit is five or
more. If this digit is less than five, no
rounding occurs.
Errors – When you make an incorrect
entry, or the answer is beyond the
range of the calculator, it will display
the word “Error.” To clear an error condi-
tion you must hit the
o button.
At this point you must determine what
caused the error and rekey the problem.
An error will also occur if you enter a
mathematical impossibility such as divi-
sion by zero.
Clear All – Your calculator is equipped
with a special two-key sequence,
C x
to clear all Memory registers to their
default values.
Battery Information – Your calculator is
powered by a single 3-Volt Lithium CR
2032 battery. This should last upwards
of 800 hours of actual use (one year
plus for most people). Should the dis-
play become very dim or erratic, replace
the battery.
