Calculator
The calculator in your phone provides basic arithmetic and trigonometric 
functions, calculates the square and the square root, the inverse of a number, 
and converts currency values.
Note: This calculator has limited accuracy and is designed for simple calculations.
Select Menu > Organizer > Calculator. When 0 is displayed on the screen, 
enter the first number in the calculation. Press # for a decimal point. Scroll 
to the desired operation or function or select it from the Options. Enter the 
second number. Repeat this sequence as many times as it is necessary. To start 
a new calculation, first select and hold Clear.
To perform a currency conversion, select Menu > Organizer > Calculator. To 
save the exchange rate, select Options > Exchange rate. Select either of the 
displayed options. Enter the exchange rate, press # for a decimal point, and 
select OK. The exchange rate remains in the memory until you replace it with 
another one. To perform the currency conversion, enter the amount to be 
converted, and select Options > To home or To foreign.
Note: When you change base currency, you must enter new exchange rates 
because all previously set exchange rates are cleared.
