3.7 Keypad Operation
All of the menu screens that require numeric entry use a common
keypad control. An example of the gain entry keypad is shown
below.
New values are entered using the numeric keypad buttons.
Some entries accept a decimal point and polarity. Click the "Positive
and negative" button to switch the positive and negative values of
the numbers.
The DEL button erases the current entry.
The "ESC" button exits the editing window without saving any
changes.
The ENTER button checks the value according to the maximum and
minimum limits and applies the new value if it is within acceptable
range. If the entered value is outside either of the applicable limits,
the entered number and the violated limit are marked in red and as
shown in the example below.
The system will prompt the current maximum and minimum values
that can be set in red font.
