backspace display button may be used to edit the number.
A line number must always be entered as a three-digit number.
Line numbers from to 99 must be entered with a leading zero
(line 020, for example). Similarly, line numbers less than 10 must
be entered with two leading zeros (line 002, for example).

non-expanded system and three on an expanded system. The
DN length can be changed in Configuration programming.
