3. Use the barrier like walls to
increase the isolation.
4. Reduce the booster’s gain by
external attenuator or replace
with lower gain antenna if the
above methods don’t work.
Problem
Resolution
The signal booster has no power.
Check that the AC outlet is working.
The booster’s power is on but the phone is
not connected into the network and still
cannot communicate.
Try to fasten the connections between the
different parts of the system.
Change the direction of donor antenna or its
installation position.
Use barriers (like buildings) to block signals of
other operators.
Good downlink signal with poor
communication quality.
Check whether there’s interference.
Consult the operator whether the signal
source base station works well.
The power is on but the coverage is not
good.
Firstly check the “ISO”, “ALC” and other LCD
indication, take actions according to the
description of Booster Commissioning
(Page14, Page15 and Page16).
The Manufacturer's rated output power of this equipment is for single carrier operation.
For situations when multiple carrier signals are present, the rating would have to be
reduced by 3.5dB, especially where the output signal is re-radiated and can cause
interference to adjacent band users. This power reduction is to be by means of input
power or gain reduction and not by an attenuator at the output of the device.
La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne
son fonctionnement avec porteuse unique. Pour des appareils avec porteuses
multiples, on doit réduire la valeur nominale de 3, 5 dB, surtout si le signal de sortie est
