There is a seperate level indicator for the original signal, channels 1...6 and for the talk-
back-channel (service). The system's levels should be set so that the yellow "0dB" –
LED lights up at level peaks, the red „+3dB“ – LED should not light up.
4.4 Operating the interpreter conference terminals
The interpreter-unit IS6IU is used to monitor the original signal and simultaneously in-
terpreting via a pre-selected output-channel.

In the seven-segment display the number of the preselected channel, choosen via the
pre-selection-switch, is shown.

By pressing a pre-selection push-button the output-channel is choosen. The number of
the choosen channel is shown in the display. At the same time the yellow LED in the
pressed push-button lights up.
The selection takes place when the push-button „CHANNEL SWITCH B“ is pressed,
where for confirmation a yellow LED lights up.
The red LEDs at the busy – indicator („CHANNEL BUSY“) are showing the occupied
output-channels (also the own channel).
At the central unit in the associated section Sektion „INTERPRETER BOOTH 1..6“ the
yellow LED belonging to the channel lights up.
4.4.1.2 Channel A
After pressing the push-button „CHANNEL SWITCH A“ the output channel, which is as-
signed from the central unit, is activated. For confirmation the yellow LED in the push-
button lights up and the yellow LED in the push-button „CHANNEL SWITCH B“ goes
out. At the busy-indication the red LED of the activated channel lights up. At the central
unit the yellow LED of the activated channel lights up too. The LED of the channel acti-
vated before goes out.
4.4.1.3 Interrupt A
If at a connected, optional service-conference terminal the switch „BASIC FLOOR“ is
activated, all connected conference terminals are being forced to switch to the channel
assigned from the central unit and „A“ is shown in the 7-segment-display. At all confe-
rence terminals the LED’s in the push-buttons „CHANNEL SWITCH A“ and „CHANNEL
SWITCH B“ as well as the LED’s in the pre-selection push-buttons are going out. At the
busy-indication the activated channels are lighting up an at the central unit the yellow
LED’s of the allocated channels are lighting up.
4.4.2 Check-in of conference terminal
To turn on the conference terminal the push-button „MICRO“ hast to be pressed. For
