5.2 Errata
5.2.1 Quick Reference Card DCN-IDESK
The message functionality operates as follows:
When the interpreter desk receives a message, the
message is displayed directly on the display. When
pressing the message button the message will be
erased from the display.
The message is not displayed when pressing the
message button again.
5.2.2 Integrus Manual: standby function
When switching off the DCN Next Generation CCU,
the Integrus transmitter indicates “Network Error”
and not “standby”. However, the radiators do switch
to the standby mode. When the DCN Next
Generation CCU is switched on again, the Integrus
transmitter and the radiators return to the “on”
mode.
5.3 Known limitations
5.3.1 System: reset of units after connecting
new units to a trunk
When a device to a LBB 4114/00 or LBB 4115/00,
which is connected to the DCN-CCU Central
Control Unit, it can happen that all units in that
same trunk reset. After reset the units come back to
default settings. The units in the trunk will not reset
if a unit is connected to a Tap-off outlet of a LBB
4115/00 Splitter protected.
If it is important that the channel selectors are not
reset to default in above described situation: use
the auto restore function of the channel selector.
See the Installation and User Instruction for how to
set the auto restore function.
If it is important that you can connect and replace
each unit during operation, without the above
described reset behavior: power the units with the
DCN-EPS Extension Power Supply Unit. The DCN-
EPS Extension Power Supply Unit is less prone to
the inrush current
5.3.2 Use of Developers Toolkit
The developers toolkit provided on this CD-ROM
can only be used with Windows 2000.
5.3.3 Text “starting” remains on CCU
In a system with an Audio Expander and an
Integrus transmitter, the text “starting” can remain
on the display of the CCU after start up. On the
display of the Audio Expanders 'No Network' is
flashing.
Switch the network mode of the Integrus transmitter
to enabled and the problem will be solved.
5.3.4 Network mode disabled results in faults
When the network mode of a transmitter is set to
disabled, while connected to a DCN Next
Generation system, noise on the loudspeakers in
the DCN Next Generation system can occur.
Switch the network mode of the Integrus transmitter
to enabled and the problem will be solved.
