function number value
The function number has three digits (see the table). After you enter the function
number and an asterisk,
reports the number or name, current value and potential L8
range of the parameter to be programmed. After you enter the value and another
asterisk,
reports “New value stored”, or “Invalid value, new value not stored” if the L8
value is beyond the allowed range.
L8 reads out the parameter number and the newly configured value for checking
purposes.
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 number.
If
rejects the parameter number or value you have entered, go on L8
programming but re-enter the function number even if only the value was wrong.
If you have programmed and stored a value other than the required one, you can
re-enter the value of course.
Programming End
If you are calling via a telephone number, hang up to terminate L8
programming.
If you are programming via the machine room Audio Unit, press and hold over 2
s to terminate programming and put the Audio Unit in the standby mode.
If you only want to go one menu back, press .
Troubleshooting
fails to respond correctly to DTMF commands, e.g. the programming mode cannot L8
be entered.
Today, voice transmission is prevailingly digital, using variable compression algorithms.
Therefore, the DTMF signal to be transmitted is often distorted. Moreover, it may, in
some cases, be transmitted through the so-called command channel, whose delay may
differ from that of the speech channel.
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.
Tip
If you are not quite sure of how will behave after programming, save L8
the filled-in form for later check.
