Calculator Operation
Jumping Between Calculator Mode and Normal Operation
If you want to return keyboard functionality to the coax screen without losing the
calculator display, press the F12/F24 key. Make the changes to the coax screen, then
press the Alt and F12/F24 keys to return to Calculator mode.
Even though the 104-key keyboard does not have a numeric keypad, you can still use the
calculator. All operations have alternative methods of entry from the main keypad as
described in the following pages.
Decimal Calculator
Use the decimal and numeric keys on the numeric keypad or the main keypad to enter
numbers for calculation.
After entering a number, enter the mathematical symbol designating the operation to be
performed. On the 104-key keyboard, you must use the main keypad.
+ for addition
- for subtraction
* for multiplication
÷ or / for division
If you want to enter a negative number, enter the number and then press the +/- key
indicated on the calculator simulation.
Press the = key on the calculator simulation (or on the main keypad) to display the result
of your computation in the calculator’s Results field.
Setting the Decimal Place
You can set from 0 through 9 decimal places on the calculator or you can choose to not
specify the number of decimal places.
If you select 0 through 9 decimal places, only the number of decimal places you select is
displayed in the Results field of the calculator. You can enter numbers for calculation
with more decimal places than can be displayed in the Results field. If the result of the
calculation has more decimal places than can be displayed in the Results field, the system
rounds off the answer before it is displayed.
You can also choose to not specify the number of decimal places. If you do not specify
the number of decimal places, the calculator displays as many decimal places as necessary
for the answer.
Note: The calculator can display a maximum of 13 digits in the Results field. If a
calculation causes a result larger than the Results field maximum of 13 digits,
the overflow symbol ? is displayed. Press C/E (Clear Entry [Clear on the
104-key keyboards]) to continue with calculations.
