DCN-DIS Discussion Unit
Problem Hint
– Not possible to initialize the DCN
Discussion Units. – The DCN signal is re-generated too
many times (refer to DCN design,
page 64).
– The trunk is too long (refer to DCN
design, page 64).
– The DCN signal is not re-generated
each 100 m (refer to DCN design,
page 64).
– Depending on menu setting 8L, at two or
more units the microphone indicator ring
is flashing or continues red. The LEDs of
the microphone buttons are off. 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).
– Unit fully operational but no audio to the
loudspeaker or 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).
– Although the system powers the trunks,
units are not operational. The DCN contains a defective extension
cable. Find the defective extension cable
and replace it. The defective extension
cable can be anywhere in the DCN.
– A unit does not operate as expected. The discussion unit is not in the correct
mode. Refer to DCN-DIS and DCN-WD
discussion units, page 208 > Discussion
unit Modes.
