•Arithmetic and currency conversion calculation input and result values can be up to eight digits for positive values, and seven digits for negative values.

•Exiting the Calculator Mode causes all currently displayed values to be cleared.

How the Cbutton affects the current screen in the Calculator Mode

•Pressing C while the current screen (arithmetic calculator or currency converter screen) shows a value other than zero will clear the screen to zero, without changing to the other screen.

•Pressing C while an E (error) indicator is displayed clears the E (error) indicator, but does not clear the current calculation to zero.

•Pressing C while the current screen (arithmetic calculator or currency converter screen) is cleared to zero, will switch to the other screen.

Performing Arithmetic Calculations

You can perform the following types of arithmetic calculations in the Calculator Mode: addition, subtraction, multiplication, division, arithmetic constants, powers, and approximate values.

To perform arithmetic calculations

When the calculator screen is displayed in the Calculator Mode, you can use the keypad to input calculations just as you do with any standard calculator. See the examples below for details.

•Be sure to press Cto clear the arithmetic calculator

screen to zero before beginning each calculation. If the screen is already cleared, pressing Cwill switch to the

currency converter screen.

• While you are inputting a calculation, values are displayed in the value input area, and operators are displayed in the operator area of the display.

•To perform a constant calculation, input the value you want to use as a constant and

then press one of the arithmetic operator keys twice. This makes the value you input a constant, which is indicated by the n indicator next to the operator symbol.

•An E (error) indicator will appear whenever the result of a calculation exceeds 8 digits. Press C to clear the error indicator. After that, you will be able to continue the calculation using an approximate result.

•The following table describes how to correct input errors and how to clear the calculator after you finish using it.

Currency Conversion Calculations

You can register a single currency exchange rate for quick and easy conversion to another currency.

•The default conversion rate is ⋅ 0 (multiply the input value by 0). ⋅ represents the multiplication operator and 0 is the exchange rate. Be sure to change the value to the exchange rate value and the operator (multiplication or division) you want to use.
