Refer to Sections 4.2.2 and 4.3.2.
The LED rings on the GN 15/30/50 Installation Modules
will be powered from the phantom supply. (See also Sec-
tion 4.3.1.)
To obtain an open channel indication, the installation tech-
nician may connect the LED ring to an external power
source. In this mode, the LED ring will light much more
brightly to draw the required attention to the open micro-
phone.
