Checking the system and detecting problems – “System”

The “System” submenu provides information on the current status of your confer- ence system and any errors that have occured.

After switch-on, the central unit automatically performs a self-test. If errors are detected during the self-test, the error icons K to N indicate the type of error encountered. When the error icons M to N appear, the display panel changes from orange to red.

The central unit also checks the conference system for errors during a running conference and, if necessary, shows the following icons to indicate these errors.

To ensure trouble-free operation of your conference system:

￿Carry out the following steps before starting the conference.

This allows you to diagnose and remedy errors in your conference system at an early stage.

￿Set up your entire conference system.

If you do not yet know the final number of participants, take the maximum number of participants as a starting point. Connect the corresponding number of conference units to the central unit.

￿Switch the central unit on.

The central unit performs a self-test.

If the number of participants increases after an error-free self-test, we strongly recommend you to perform a new self-test before starting your conference.

If an error or a warning occurs, proceed as follows:

￿Eliminate the error (see the following tables).

￿After error elimination, perform a manual self-test by selecting “Yes” in the “Start Self-Test” menu item:

Main Menu

Start Self-Test

Select and call up the “Start Self-Test” menu item

Select the desired setting; apply the setting

The central unit now checks if the reported error still occurs. If the error has been eliminated, the corresponding error icon will go off after the self-test.
