POWER
Green
On = Power on
Off
– Power off
FAULT
Red
On = Internal voltage regulator fault, over-temperature
fault, or PLL phase lock fault
Off = No faults
TEMP
Red
On = Over-temperature fault
Off = No over-temperature fault
When power is first applied, an LED test will be performed and all LEDs will illuminate for 1 second.
The POWER LED will illuminate whenever power is applied to the unit.
The FAULT LED will illuminate when an internal regulator is not producing the proper voltage, the internal
temperature is too high, or the PLL has lost phase lock. The unit will be muted while the fault condition
exists.
The TEMP LED will illuminate when the internal temperature is too high. The unit will be muted while this
fault condition exists.
