*For a single calculation, calculation error is ±1 at the 10th digit. (In the
case of exponential display, calculation error is ±1 at the last significant
digit.) Errors are cumulative in the case of consecutive calculations, which
can also cause them to become large. (This is also true of internal
consecutive calculations that are performed in the case of ^(x
y
),

y , x!,

, nPr, nCr, etc.)
In the vicinity of a function’s singular point and point of inflection, errors
are cumulative and may become large.
Power Supply
The type of battery you should use depends on the model number of your
calculator.

The TWO WAY POWER system actually has two power supplies: a solar
cell and a G13 Type (LR44) button battery. Normally, calculators equipped
with a solar cell alone can operate only when relatively bright light is
present. The TWO WAY POWER system, however, lets you continue to use
the calculator as long as there is enough light to read the display.
• Replacing the Battery
Either of the following symptoms indicates battery power is low, and that
the battery should be replaced.
•Display figures are dim and difficult to read in areas where there is little
light available.
•Nothing appears on the display when you press the 5 key.
