LN Programming 3.1

Note
 You are recommended to change it to secure your equipment against
unauthorised access.
 If you forget your password, contact the manufacturer to recover your
data.
Programming Procedure
Having entered the programming mode, you can change any programmable value(s)
in any order. Proceed as follows: enter the function number and then the value. Use
an asterisk as a separator or Enter. In general, the function has the following format:
function number value
The function number has three digits (see the table). After you enter the function
number and an asterisk, LN reports the number or name, current value and potential
range of the parameter to be programmed. After you enter the value and another
asterisk, LN reports “Value stored”, or “Invalid value” if the value is beyond the
allowed range.
Warning
 A drawback of some telephone sets is that, after you press a button, i.e.
send a DTMF signal, they go “deaf” for a fraction of a second. In that case,
you cannot hear the whole text and are recommended to use another
telephone.
Programming Error
If you make a mistake during entering (the function number or value) and have not
entered an asterisk yet, you can cancel the whole number by pressing
and re-enter
the digits.
If LN rejects a parameter number or value you have entered, go on programming but
re-enter the function number even if it was the value not the number that was wrong.
If you have programmed and stored a value other than you intended to, you can re-
enter the value of course.
Programming End
Having stored all values to be changed, terminate programming by pressing . LN
sends a hang-up signal and hangs up. If you do not use the character, LN hangs up
later without affecting the stored values (the values are stored immediately after
being entered).
If you are not quite sure of LN’s programming behaviour, save the filled-in form for
later check.
Troubleshooting
LN fails to respond correctly to DTMF commands, e.g. the programming mode cannot
be entered.
