User set-up

5. 1

Public areas

5.1.1 Hall displays
Put the hall displays in a position where users can easily
see the display. Do not put the display in direct lighting
or sunlight. The following has an effect on the visibility
for the specified system:
• The distance that is necessary to see the display.
• The character size of the displays.
• Contrast and intensity of the lighting conditions.
The supplier of the hall display recommends all
necessary adjustments.
5.1.2 Public areas and Walkways
Keep public areas clear of system and extension cables
and connections.
5.2

Headphones/headsets

Put headphones and headsets with:
• Interpreter desks.
• Concentus delegate and chairman units.
• Channel selectors.
• Discussion units.
• Integrus receivers.
Acoustic feedback between the connected headphones
or headsets and the microphone occurs when:
• The volume level is set too high.
• The headphones are too close to enabled
microphones.
You must tell the users to keep sufficient distance from
the microphones or not to set the volume level higher
than is necessary. Refer to section 6.7.
