Alarm LED: Indicates the strength of received signal from the tower. Flashing
Alarm means that the booster is receiving a strong signal in one or more of the
bands. Alarm LED shall remain "Green" or "Slow Flashing Green". Slow flashing
green indicates that everything is working well and the booster is working at
nearly the optimum output power to achieve the best possible coverage.
LED Status
Green @ ALC≤0
Slow Flashing
Green@ ALC =
1~14dB
Alarm LED
Quick Flashing
Green@ ALC =
15~21dB
Quick Flashing
Red @
ALC≥22dB
Measures: The below actions are recommended to eliminate "Quick Flashing
Green" and "Quick Flashing Red".
1. Adjust the antennas' directions or locations to lower downlink received
signal level.
2. Slowly reduce the downlink gain using the Manual Gain Controls.
3. If the above methods don't work, reduce the booster's gain with an
external attenuator in line with the outdoor antenna or replace with
lower gain antenna.
Target: The overload issues are fixed when the Alarm LED is "Green"or "Slow
Flashing Green". Please note that a "Green" LED indication may result in smaller
coverage area. This can be improved by adjusting the outdoor antenna to receive
a stronger signal.
Meaning
Output power is not
maximum.
Full output power
Output power is too
high.
The booster
automatically shuts off
for protection from
excessive downlink signal
from tower.

Solution methods
Check coverage, leave as
is if it's good; if coverage
is not good, increase
downlink signal Level.
