Step 4. Booster Commissioning
Overview: The booster has an intelligent startup system; booster commissioning is an
automatic process able to guarantee system optimal performance.
As soon as you finish booster system installation, plug it in a power supply to power on the
booster. It will start working and checking the receiving signal strength and the isolation to
ensure best system performance. Automatic adjustment will take about 3-5 seconds.
After the booster starts, check if the coverage is improved as you wish. The booster
commissioning is completed.
In case the coverage is not enough, please check the following conditions.
The rated output power is reached, but the coverage is not enough or the signal in some

areas are not improved:
 Check whether the indoor antenna is installed correctly or not, try to change the
antenna position to improve coverage.

Check if it is necessary to adjust the direction of the indoor antenna.

Check whether it is necessary to add more indoor antennas since barriers block the
signal.
The rated output power is not reached.

Change the position or direction of the outdoor antenna to get a stronger receiving
signal and higher output power.

Alarm Status: indicates if the booster has enough isolation between outdoor and indoor
antennas in order to avoid loop back or so-called self-oscillation. Hiboost is an ideal
mechanism. Smart AGC, to avoid interference with operator mobile networks. "Alarm"
long-team up on LCD display means not only device is powering on, but also ISO function is
working great and self-oscillation has been eliminated.
