Persistent Status and Error information
Automatic safety precautions are built into the amplifier system. In the case of a catastrophic system event, a shutdown circuit is
incorporated that will disable all emissions should the uplink input or downlink input be overdriven or should an oscillation or output
overpower event occur. The amplifier will periodically attempt to recover from the detected condition automatically. Warning light
indicators are as follows:

overpower event occur. The amplifier will periodically attempt to recover from the detected condition automatically. Warning light
indicators are as follows:
UL PWR:
Indicated by a red LED. Uplink power has been affected by a system event and
will need to be addressed by either the system software or a technician to
be reset to original system settings, using the GUI or text menu interface.
See the event log to determine the nature of the fault.

DL PWR:
Indicated by a red LED. Downlink power has been affected by a system event
or condition, such as insufficient antenna isolation, and will need to be
addressed by either the system software or a technician to be reset to original
system settings, using the GUI or menu driven user interface. See the event log
to determine the nature of the fault.

OSC:
Indicated by a red LED. An oscillation event has occurred or is occurring. The
system has been affected by the event and the problem will need to be
addressed by the system software or a technician to be reset to original ystem
settings. This is an indication of a major fault.

SHUT DWN:
Indicated by a red LED. The RF stages of the unit are disabled due to an
unresolved system event such as oscillation, effectively taking the unit off
unresolved system event such as oscillation, effectively taking the unit off
the air. The problem will need to be addressed by a technician before the on
air operation can be restarted. The repeater is not equipped with an ON/OFF
power switch. Hard power down will require that the unit be unplugged.

D/L SIGNAL
STRENGTH:
STRENGTH:
Indicated by a green LED bargraph. This indicates the relative signal strength
being received from the cell site. Note: the last bar of the bargraph will turn
red in the event of very strong adjacent channel interference.

red in the event of very strong adjacent channel interference.
Alarm:
Indicated by a red LED. The unit has sensed an alarm condition. This LED may
light alone or in conjunction with one of the other indicator LEDs. In both cases the
cause(s) can be reviewed by going to the System Health menu.

cause(s) can be reviewed by going to the System Health menu.
AGC:
When Illuminated, this yellow LED indicates that automatic gain control is active
and has reduced the gain of the unit in order to prevent very strong input
signals from overloading the amplifier. The amplifier will periodically evaluate
input signal and attempt to recover from this condition.
