ENERAL 

 

This section provides the maintenance and troubleshooting procedures for the 
Mini-Repeater.  

8.2 P

ERIODIC 

M

AINTENANCE

 

There is no periodic maintenance required for the Mini-Repeater. As long as it 
is installed in a shaded area not subject to extreme temperatures and with 
adequate ventilation, it will provide long term, problem-free operation.

Mini-Repeater Deko2119 provides two modes for failure display:  

•

 

Status Leds in Mini-Repeater

Alarms screen in Deko-RMS Workstation  

The following paragraphs provide first a description of the LED alarms in the 
Mini-Repeater, then a description of the Alarm functions in the Deko-RMS

ROUBLESHOOTING

 

8.4.1 Status LEDs Indications 

The Mini-Repeater includes three LEDs (DL, Power, UL) on its front panel 
(see Figure 2).  Check the following normal LEDs status on the front panel of 
the Repeater:  

•

 

At turn on, the LEDs show the built-in test 
procedures: the LEDs turn from Orange to Red to 
Green.   

•

 

During normal operation, all LEDs are green  

•

 

LEDs in Red signify major malfunction.  Orange 
displays high input power.  Blinking Green shows 
low power transmission.  

Whenever the LEDs are lit differently after the startup test is completed, they 
indicate a malfunction.  Refer to the following paragraph for troubleshooting.  

8.4.2 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.
