The Alero front panel is the only side that should be visible in a typical setup. Here, the user can monitor the most essential
statuses in three groups of LEDs as shown in FIG. 4.
The table below provides descriptions of the front panel LEDs used to determine the state of the unit and operation of the
microphones.
