						When the floor channel volume is set to a high level or when several
		N				participants speak simultaneously, feedback noise (loud hissing) can
						occur. This can cause hearing damage.

￿Reduce the floor channel volume (see page 48, page 93 or page 101).

￿Make sure that the “Audio Gain Reduction” function is activated (see page 32). This function reduces the gain per active micro- phone by the selected level and thus prevents feedback noise.

￿Increase the distance between the individual conference units to at least 50 cm.

￿ Turn the jog dial

–to the right to increase the volume or

–to the left to reduce the volume.

The volume of the conference units’ loudspeakers can also be set via the central unit’s operating menu (see page 32) or the “Conference Manager” software (see page 93).

Adding conference units to the conference system during operation

You can add conference units to the conference system during operation.

When adding conference units to the conference system, observe the maximum number of conference units in order to ensure safe operation (see page 13).

All delegate units are ready for immediate use. The chairman units have to be re-initialized. Note that this will interrupt the conference (see page 30 or page 88).
