3.10.2 Numeric Entries
When entering values in numeric field, the required numeric value is simply typed using the
keypad and press Enter.
The default value that is initially displayed disappears upon the first numeric key press. Once a
numeric key is pressed, the Up and Down buttons are nonfunctional; they resume their normal
functions once the Enter or Exit buttons are pressed.
To delete an alphanumeric character, use the left arrow key.
To enter a negative value, press the minus key (-) on the keypad; this toggles the value between
negative and positive.
