*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 ^(xy), xy , x!, 3 , 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 5key.
