Remark:
• When increasing the downlink gain make sure the isolation is adequate
to prevent system oscillation
• Recommended ways to increase output power: Adjust the outdoor
antenna direction / location, or replace with higher gain antenna to
increase received signal strength from the tower.
Note:
The slow flashing ISO and Alarm status indicates that ISO and ALC
functions are working properly and the problems of self-oscillation and strong
downlink signals are fixed. In most cases, there is no need to take any additional
measures except for deep self-oscillation or excessively strong signals from the
tower. The self-adaptive ALC and isolation gain processing system automatically
solve most problems.
After all the LEDs are indicating properly check whether the coverage is good. If
it is good, the booster installation is complete. If the coverage is not good take
the following actions:
1. If the signals in most areas have not been improved, please check below:
• The weak downlink signal leads to the low output signal level.
Change the direction of outdoor antenna or its installation position
or replace the outdoor antenna with a higher gain antenna to
increase the received signal level.
• Check whether it is necessary to add more indoor antennas since
barriers such as walls block signal penetration. Also, check whether
the booster’s power is maximized. Install more indoor antennas or
replace amplifier with a booster of higher power level.
2. If the signals in a small part of the building have not been improved,
please check the following
• Check whether the indoor antenna is installed correctly or not. Try
to move the antenna location to improve coverage.
• Check if it is necessary to adjust the pointing direction of the
indoor antenna.
• Check whether it is necessary to add one or more antennas to
enhance the coverage of special areas.
