may take a few seconds.
The display shows: “

—> Then the cable NIT is generated, added and sent to
all QAM Cassettes. The other QAM Cassettes also
add this new cable NIT. The status of all QAM Cas-
settes in the NIT menu changes to “

Notes:
– The cable NITs of the other Cassettes remain acti-
vated. When it is reactivated (“

generated NIT is added again. If you have changed
parameters in the meantime, you must select “
Make
”
to generate a new, up-to-date NIT.
– All QAM Cassettes must be equipped with a TP
module, be set and ready for reception. Cassettes
without TP modules are not taken into consideration
during the NIT setting. If the NIT is activated (“
on
”)
and parameters are modified and saved, a warning
appears in the display:
“
Rebuilt NIT !!!
”.
