Desk Accessories
The Organizerís desk accessories are a set of valuable
utilities for everyday use. The Calc (Calculator) can perform
calculations on figures entered 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. In addition, it has a powerful currency
/ units conversion function.
Using the arithmetic calculator
1. Press to enter the Main Menu and select CALC, then
press .
2. Perform the calculation using the numeric and
mathematical symbol keys on the keyboard, just as you
would with a regular electronic calculator.
To quit the Calc application, simply change to any other
application by pressing the corresponding key.
To clear an entered value, press once. To clear an
entire calculator operation, press twice.
Calculations are performed in the order of entry, not
according to algebraic operator precedence, ie., the
calculation 8 + 2 x 3 is performed as: (8 + 2) x 3 not 8
+ (2 x 3). This is just as for a regular electronic calculator.
An M shown on the display indicates that a value is
stored in the calculatorís memory. Press
twice to
clear the memory.
Press to change the sign of a displayed value.
Press to erase the last digit typed.
An E shown on the display indicates an error, usually
an overflow error (when no more digits can be
displayed). When this happens, the calculator will
usually ignore any subsequent input until the error is
cleared. press
to clear the error.
For further information on other calculator operations,
see p.37.
When E appears
When any of the following situations occur, the error indicator
E is displayed and calculations are suspended. Press

clear the error.
