Calculator
The calculator in your phone provides basic arithmetic and trigonometric functions; calculates
the square, the square root, and 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. Press * for additional functions. Scroll to,
and select, the desired operation or function. 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.

Stopwatch

You can measure time, take intermediate times, or take lap times using the stopwatch. During
timing, the other functions of the phone can be used. To set the stopwatch timing in the
background, press the end key.
Using the stopwatch, or allowing it to run in the background when using other features,
increases the demand on battery power and reduces the battery life.
Select Menu > Organizer > Stopwatch and from the following options:
Split timing — to take intermediate times. To start timing, select Start. Select Split every
time that you want to take an intermediate time. To stop timing, select Stop.
To save the measured time, select Save.
To start timing again, select Options > Start. The new time is added to the previous time.
To reset the time without saving it, select Reset.
