5.2Errata

5.2.1Quick 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.

5.2.2Integrus 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.

5.3.1System: 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

5.3.2Use of Developers Toolkit

The developers toolkit provided on this CD-ROM can only be used with Windows 2000.

5.3.3Text “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.

5.3.4Network 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.
