Desk Accessories
The Organizer’s desk accessories are a set of
valuable utilities for everyday use. The Calc
(Calculator) can perform calculations on figures
entered by using the number keys. The Clock can
simultaneously display the day, date, and time in
any two cities of your choice. This chapter provides
all the information you need to enjoy full use of these
very useful applications.
The Calc (Calculator) Application
The Organizer provides a 12-digit calculator which performs
mathematical operations, including square root and percentage
calculations. The Calc application also provides support for
cost/selling price markup and margin calculations. In addition,
it has a powerful currency/units conversion function.
There are four different display options in the Calc application,
and the application always opens with the most recently used
display.
* To move between the different calculator modes, either
press [CALC/CONV] repeatedly until the desired mode
appears, or select VIEWS from the calculator menu and
then select the desired mode.
Using the arithmetic calculator
1. Press [CALC/CONV] to start the application.
2. Perform the calculation using the numeric and
mathematical symbol keys on the keyboard, just as you
would with a regular electronic calculator.
