Troubleshooting 

 

 

The repeater unit contains no user serviceable parts and should not 

require maintenance.  Two LEDs on the unit will indicate its current 

operating state.   

Indication Cause 

Action 

Power LED is off, 
status LED is off 

The repeater does not have 
power applied to it 

Check the power supply 
connection. 

Power LED is on, 
status LED is off 

The repeater is operating 
normally 

None. 

Power LED is on, 
status LED is 
amber and flashing 

The repeater has reduced 
its downlink gain to 
maintain network 
compatibility.  The signal 
received at the outdoor 
antenna may be too strong, 
or there is feedback 
between the indoor and 
outdoor antenna. 

Try relocating the outdoor 
antenna, or rotating it (if a 
directional antenna was 
used).  A RF pad may 
need to be installed at 
the outdoor antenna to 
reduce gain. 

Power LED is on, 
status LED is 
green and flashing 

The repeater has reduced 
its uplink gain to maintain 
network compatibility.  This 
is usually caused by a 
handset being used too 
close to the interior 
antenna. 

None.  The repeater will 
automatically return to full 
gain when conditions 
permit.  If the condition 
persists when no handset 
is nearby, relocate the 
indoor and/or outdoor 
antennas to get more 
isolation. 

Power LED is off, 
status LED is red 
and flashing 

The repeater is off-line due 
to a high temperature fault.  
The repeater will restart 
automatically when the unit 
cools down 

Determine the cause of 
the overheating (e.g., hot 
environment, inadequate 
airflow).  Possibly re-
locate the amplifier to a 
cooler location. 

Power LED is 
flashing, status 
LED is red 

The repeater has detected 
an internal fault and is off-
line. 

Interrupt power to the unit 
to see if it returns to 
normal operation, 
otherwise service is 
required.
