8.6 Indicator
Each microphone has a green led built within the enclosure which is only visible and may be
controlled during commissioning and (operational performance) testing.
The microphone contains an internal buzzer which is used during audio testing. This sounds
when the green led is ON and is normally OFF.
8.7 Errors
If errors occur these will be indicated on the display of the Bridge Control Unit.
8.8 Configuration
The microphone adopts the input that the microphone is connected to on the NW6031 Audio
Hub. For example, Input 1 will have the description āAudioHub PN4001 Channel 1ā when the
system is probed initially.
8.9 Operating instructions
After commissioning of the VDR system, the microphone does not require (crew) operating
instructions. Microphone tests may be performed manually from the Bridge Control Unit.
