•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 C to clear the arithmetic calculator screen to zero before beginning each calculation. If the screen is already cleared, pressing C will 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.
To change the exchange rate and the operator
1. While the currency converter screen is displayed in the Calculator Mode, hold down A until the exchange rate starts to flash on the display. This is the setting screen.
2. Use the keypad to input the exchange rate and the operator ([⋅]or [÷]) you want to use.
• To clear the displayed exchange rate to zero, press C.
3. Press A to exit the setting screen.
To check the current exchange rate and operator setting
1.While the currency converter screen is displayed in the Calculator Mode, hold down
A until the exchange rate starts to flash on the display. This is the setting screen.
• The setting screen will also show the current exchange rate and operator setting.
2.Press A to exit the setting screen.
To perform a currency conversion calculation
1.While the currency converter screen is displayed in the Calculator Mode, use the keypad to input the value from which you want to convert.
2.Press [=PM] to display the conversion result.
3.Press C to clear the conversion result.
•An E (error) indicator appears on the display when the result of a calculation exceeds 8 digits. Press C to clear the error indicator.
•Pressing [=PM] while a calculation result is displayed will apply the conversion rate again to the displayed value.
