Operation Manual
Conference System
Check whether each sub system
operates correctly in single CCU
mode (refer to DCN-CCU2 and DCN-
CCUB2 Central Control Units, page
183).
Disturbance on the optical network
caused by connecting a device in a
running system could cause a
problem. If the problem persists:
switch off and on one by one all
devices connected with the optical
network, starting with the master
CCU (refer to Optical network design,
page 77).
The WAP contains an incompatible
Software version. Download the
software version as used on the CCU
to the WAP via the DLT program.
a bad signal of the wireless
discussion units is notified.
Move the unit closer to the WAP.
Check for other WiFi networks.
a low battery for a wireless
discussion unit is notified.
Replace or charge the battery.
In case of heavy disturbance on
2.4GHz, the system informs the
operator with a bad signal warning
on display CCU or in DCN-SWSMV. In
case more investigation is needed, it
is possible to analyze the logging file
of DCN-SWSMV.
