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.
