impedance of coax will put an extra load on your Booster, shorten its life span and decrease the system
performance.
9.3. Booster Settings
Please check very carefully all cable connections are correct and firm before running operation test and then
carry out following tests.
9.3.1. Switch on power
After power is on, check firstly the alarm and power LEDS.
z Status and definition of POWER indicators:
z Status and Definition of ALARM LED indicators; Alarm LED only works for downlink signals.
Status
ALARM
Green
It is working in linearity
Warning: Input signals may be not enough, so please check on coverage
effect, do not do anything if it is good coverage; otherwise please adjust the
Booster system to get better coverage.
Orange
A little bit stronger input signals or slight self oscillation have occurred.
Solution: Please adjust antennas or use MGC to reduce the Booster gain, till
you find “edge point” with green LED (I.E. the Alarm LED must stay at green
color, and at the edge of turning Orange), and let the Booster work at this point.
MGC is the last measure to take as it will shorten the coverage.
Red for 5
seconds and
then off
There are strong input signals or severe self oscillations (loop), please enlarge
the distance or make use of barriers between antennas, or adjust the antennas’
angles, and last step is to adjust the Booster by DIP switch.
Remark: Please note that Alarm LED works on Booster downlink signals only. I.E. the Booster input
signals from CELL TOWER.
Single system Booster only has one set of power and alarm LEDS, while dual system have two sets
