Whenever the LEDs are lit differently after the startup test is completed, they indicate a
malfunction. Refer to the following paragraph for troubleshooting.
LED Condition Description and Recommended Response
DL LED Blinks Green A blinking green DL LED indicates a low input signal at
the Donor antenna. As a result, the Mini-Repeater
cannot provide a sufficient power output.
Most probable cause Low input
signal at the Donor antenna.
Corrective action Check the
Donor antenna output power, and try aim it to obtain
maximum signal from the BTS.
DL LED Is Constantly Lit In
Orange
A constant orange DL LED indicates two optional
operational statuses: Donor power input too high or low
isolation in the system.
Most probable cause Donor
power input is too high.
Corrective action Lower the
input power by either setting the antenna to receive
less power, or by adding an attenuator at the BASE
connector.
Caution! Turn off (disconnect from mains) the repeater
before connecting
the attenuator. Once installed, turn the power on.
Second most probable cause Isolation of
the system, or internal problem. If the UL Led is also lit
in Orange, the most probable cause is low isolation of
the system.
Corrective actions Verify the
isolation of the system
If the isolation is satisfactory, the Repeater is faulty.
Replace the unit.
DL LED Is Constantly Lit In
Red
A red DL LED indicates a major malfunction.
Most probable cause Repeater
failure
Corrective action Replace
the unit
Power LED Is Constantly Lit
In Red
A red Power LED indicates a major malfunction.
Most probable cause Repeater
failure due to overcurrent of
PAs or PLL out of lock
Corrective action Turn off
the Repeater (this action causes a reset of the
function), and turn it on anew. If the fault resumes,
replace the unit
Power LED Is Lit In Orange
No failures, OK
