show the start-up text. – The DCN signal is re-generated too
many times (refer to DCN design, page
64).

each 100 m (refer to DCN design,
page 64).
– Depending on menu setting 8L, the
microphone LED on top of the
loudspeaker of the Concentus delegate
units and Concentus chairman units is
flashing or continues red. The contribution devices have the same
address. Make sure that each active device
in the DCN has a unique address (refer to
Initialization, page 178 and to DCN-CCU2
and DCN-CCUB2 Central Control Units,
page 183 > Double unitID).

headphones. The audio routing mode of the central
control unit is Insertion and you did not
connect a device between audio input 2
and audio output 2 of the central control
unit (refer to DCN-CCU2 and DCN-CCUB2
Central Control Units, page 183).
