The LEDs provide the following information on status and possible faults:
Color Description Corrective Action
Green Normal (UL or DL) operation -
Red Power failure (in UL or DL)
Corrective action: Turn off the Booster (this action
causes a reset of the function), and turn it on anew.
If the fault resumes, replace the unit.

Mute - either user- or system-
initiated.
(System initiated mute may be
due to isolation problem or
temperature).
Check gain of the booster, if gain is minimum, then it
is an isolation problem. Improve isolation.
