booster starts its initialization to check it is receiving signal and the isolation status
to ensure its best performance. This will take around 3-5 seconds.
After the booster start up, please check whether the coverage is good. If it is good,
the booster system installation is complete.
You can check the output power displayed in LCD. It may vary at 1 - 3dB difference
which is normal due to outdoor signal conditions. It would be perfect that the
output power reaches its rated one for largest coverage; but you can always leave
it even though it doesn't as long as the coverage is good enough for you.
In case the coverage is not enough, please take below measures as per below
conditions.
1. The rated output power is reached, but the coverage is not enough or the
signal in specific areas has not been improved.
2. The rated output power is not reached.
A) Please adjust outdoor antenna to get a stronger receiving signal in order to
get higher output power (not necessarily to reach rated value as long as the
coverage is enough).
B) Please observe the LCD display, if the reading gain is less than rated value
and "ISO" is flashing, it means the gain is reduced by ISO function for not
having enough isolation.
Measures:
One of below actions are recommended to eliminate ISO problems
and increase the gain:
Check whether indoor antenna is installed correctly or not. You may try to
move the antenna location to improve coverage.
Check if it is necessary to adjust the direction of indoor antenna.
Check whether it is necessary to add more indoor antennas since barriers
block the signal penetration.
Adjust antenna's directions or locations, or increase the distance between them.
Increase the vertical or horizontal distance between donor antenna (exterior
antenna) and server antenna (interior antenna).
Use the barrier, such as walls, to increase the isolation.
Change server antenna (server antenna can be changed to other antenna type
which has better directional antenna pattern, also you can let server antenna
and donor antenna point opposite directions).
Reduce the booster's downlink gain by the control button. Keep uplink
attenuation value and downlink attenuation value same, and then restart
the booster.
