DCN Wireless 2.32 Release Notes
4.5.2 Microphone will be reset to default after a
de-init.
When a de-init wired is activated at the WCCU the
microphone is always set to microphone mode
"open" with 2 active microphones.
4.5.3 Wireless Unit Data is cleared when
performing de-init wired.
When a de-init wired is activated at the WCCU the
wireless unit data (like microphone gain) is cleared.
4.5.4 Activated microphone of chairman 1 does
not return after using priority button by
chairman 2.
In a DCN-Wireless system it's possible to use more
than one Wireless Discussion Units as Chairman
(refer to chapter 12.4.1 of the Installation & User
Manual).
In case chairman priority is set to 'Temporarily Off'
in WCCU menu 4G and when more than one
Chairman Unit is used, it's possible that when the
microphone of chairman 1 is active and chairman 2
presses the priority button, the microphone of
chairman 1 does not switch on again, when
chairman 2 releases the priority button (even
though delegate microphones do come on again).
4.5.5 Abort system control with DCN-SWSMV
can cause acoustic feedback.
The audio volume of the DCN-Wireless system can
be controlled from the DCN-SWSMV, but this is not
the same volume control as on the WCCU (refer to
figure 12.1 of the Installation & User Manual).
When the audio volume in the WCCU is too high
and the master volume control of the DCN-SWSMV
is used to reduce the audio volume to prevent
acoustic feedback, the acoustic feedback will occur
when the DCN-SWSMV is aborted.
This is normal system behavior; it is mentioned here
to remind the user.
4.5.6 Long time needed for upgrading Wireless
Access Point (DCN-WAP).
The Download and License Tool can be used for
upgrading. When "Down Load Optical" is selected,
all applicable device connected to the optical
network will be upgraded. In case the DCN-WAP is
connected, it will take more than 30 minutes to
upgrade the DCN-WAP.
Bypass: In case the DCN-WAP does not need to be
upgraded, do not connect the DCN-WAP when
selecting "Down Load Optical".
This is normal system behavior; it is mentioned here
to remind the user.

4.5.7 Text "starting" remains on WCCU
In a system with an Audio Expander and an
Integrus transmitter, the text "starting" can remain
on the display of the WCCU 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.
4.5.8 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.
4.5.9 No audio on Loudspeakers or Headphones
of Wireless Discussion Units, or one of the
enabled Microphones not working
After starting the DCN-Wireless system it might
occur (seldom) that there is no audio on
Loudspeakers or Headphones of Wireless
Discussion Units, or one of the enabled
Microphones not working. (This does not occur
during operation, but only after startup)
•
A temporarily solution is to restart the
system
•
The permanent solution is to use a DCN-
WAP with HW-version 1.20 (or higher),
refer to chapter 2.2.4.
4.5.10 Sometimes Wireless Discussion Units
(WDUs), do switch 'off' after Out Of Range
or Sleep-mode
Wireless Discussion Units can be Out Of Range of
the system for 15 minutes, in case they detect the
correct system within this period the connect again.
The DCN-Wireless system can be in Sleep Mode, in
case the WDUs detect that the system has 'waken
up', they 'wake up' as well.
In both situations the WDUs might switch off and do
not recover, this is solved in release 2.32.
