3.4.1.1 The Number Pad Editor
The number pad editor is a small window that resembles the number pad on a keyboard. The
window’s title indicates the parameter being edited (the first octet of an IP address in the figure
below).
When the number pad editor is invoked, the softkey interface changes as shown on the
right side of the figure.
If a parameter already has a value when the editor is invoked, the number pad editor is
initialized with this value. Use the Clear button to erase the value entirely.
The <- button (the backspace button) erases the last digit.
The EXP button is used to enter numbers in scientific format.
The +/- button toggles the sign of the mantissa when it is pushed before the EXP button
and toggles the sign of the exponent when pushed after the EXP button.

Number pad buttons can be clicked with the mouse.
Note the white rectangle on
the button. It indicates

Use the down and right
arrow keys to move the
focus to a different button.
Press the PUSH softkey to
push the focused button.
Softkey short cut for the

parameter value you
entered, press Apply.

your edits and leave the
parameter unchanged.
With a keyboard you can directly enter a value.
